د اټومي وړانګو خوشې کول، د سرپناه سرپناه، او پوټاشیم آیوډیډ: د ګاما محافظت فزیک، د 7-10 تخریب قاعده، او د تایرایډ بلاک کول

بیړني شمیرې د هیواد له مخې توپیر لري. دا پاڼه 911 کاروي، د متحده ایالاتو او کاناډا لپاره شمیره. ډیری نور هیوادونه 112، 999، یا بل شمیره کاروي. د خپل هیواد لپاره شمیره ومومئ.

که ستاسو د 16 کیلومتره (10 میل) بیړني پلان کولو زون (EPZ) دننه د سوداګریز اټومي بریښنا فابریکې د یخولو حادثې له امله رامینځته شوی وي ، د صنعتي رادیولوژیکي خپریدو پیښه ("خندا بم") ، یا اټومي چاودنه چې د لوړې ارتفاع راډیو اکټیو پایله رامینځته کوي ، رادیولوژیکي اضطراري عمل ته اړتیا لري. د دروند کیمیاوي ګاز د خپریدو په څیر، چیرې چې زهرجن بخارونه په ټیټو پوړونو کې ډوبیږي، د ګاما وړانګو ته ننوځي (γ)** په مستقیم کرښو کې سفر کوي لکه د لوړې انرژي ایکس رے او په اسانۍ سره د لرګیو د پتلي کور سایډینګ او د موټرو شیټ فلز څخه تیریږي. په یوه پتلي فلزي موټر کې دننه د بندې لویې لارې په ترافیک کې د ناستې هڅه کول پداسې حال کې چې د راډیو اکټیو پلوم یا د رادیو بادل له سر څخه تیریږي اشغالګران د احتمالي غیر محافظت وړ وړانګو دوز ته رسوي.

د اټومي بریښنا فابریکه خوشې کول یا د راډیو اکټیو راوتلو پیښې ژوندي پاتې کیدل د روغتیا فزیک په دریو قوانینو تکیه کوي: محافظه، فاصله، او وخت (Get Inside, Stay Inside, Stay Tuned). د ځمکې لاندې تر ټولو ژورې خونې یا د څو پوړیزو کانکریټي ودانۍ په مرکز کې سمدلاسه په شا کیدو سره (چیرې چې کثافت ځمکه او معمار د 90 سلنې څخه تر 99.5 سلنې پورې د ګاما وړانګې جذبوي) ، د هوا له لارې د الفا او بیټا ذرات بندولو لپاره میخانیکي هوا بندول ، د عمر دقیق Iodtasium اداره کولKI)** یوازې هغه وخت چې د عامې روغتیا چارواکي د راډیو اکټیو آیوډین تصدیق کوي (I-131) خوشې کول، د ویښتو له کنډیشنر پرته د ویښتو د دوړو پاکول، او د 7:10 د زوال د خرابیدو اصول پلي کول، کورنۍ کولی شي د شدید وړانګو ناروغۍ او اوږدمهاله تایرایډ سرطان مخه ونیسي.

Phase 1: Understanding the 3 types of ionizing radiation and nuclear zones

To protect your family during a radiological emergency, you must distinguish between External Irradiation (gamma rays shining through walls like a flashlight beam from outside) and Internal Contamination (inhaling or swallowing microscopic radioactive dust particles that continue to irradiate your internal organs from the inside out).

Alpha, Beta, and Gamma radiation mechanics

  1. Alpha Particles (α, Helium Nuclei, e.g., Plutonium-239, Americium-241, Polonium-210):
  2. External Hazard: Almost zero. Alpha particles are heavy and travel only 2 to 5 centimeters (1 to 2 inches) in air; they are completely stopped by a single sheet of paper or the outer dead layer of human skin.
  3. Internal Hazard: Extreme. If alpha-emitting dust is inhaled into the lungs, swallowed in contaminated water, or rubbed into an open wound, it deposits massive ionizing energy directly into living mucosal cells, causing severe internal radiation injury and cancer.
  4. Defense: N95/P100 mask outdoors, shutting off home HVAC, eating only sealed food, and covering open cuts with waterproof bandages.
  5. Beta Particles (β, High-Speed Electrons, e.g., Strontium-90, Iodine-131, Cesium-137):
  6. External Hazard: Travels a few meters in air; penetrates the germinal layer of human skin, causing "Beta Burns" (painful radiation skin burns resembling severe sunburn or thermal blisters) if fallout dust sits directly on bare skin or hair for hours.
  7. Internal Hazard: High; if swallowed or inhaled, Iodine-131 concentrates in the thyroid gland and Strontium-90 mimics calcium to deposit inside human bone marrow.
  8. Defense: Removing contaminated clothing immediately, washing skin with soap and water, and staying indoors behind walls or glass windows.
  9. Gamma Rays (γ, High-Energy Photons, e.g., Cesium-137, Cobalt-60, Fission Fallout):
  10. بهرنی خطر: ډیری. د ګاما وړانګې د رڼا په سرعت سره د هوا له لارې په سلهاو متره واټن وهي او د انسان ټول بدن ته ژور ننوځي، د هډوکو میرو او د معدې د سټم حجرو ته زیان رسوي. د لرګیو پتلی دیوالونه، وچ دیوال، او د موټر دروازې په حقیقت کې د صفر محافظت وړاندیز کوي.
  11. دفاع: ** دروند ډله ایز محافظت** (د کانکریټ، بسته شوي ځمکه، خښتې، لیډ، یا اوبه) او فاصله د باندنیو بامونو او لانونو څخه چیرې چې دوړو دوړو ځای په ځای شوی وي.

د اټومي بریښنا پلانټ د بیړني پلان کولو زونونه (10-Mile vs. 50-Mile EPZ)

په متحده ایالاتو کې (د اټومي مقرراتو کمیسیون [NRC] او FEMA لخوا تنظیم شوي)، کاناډا (د کاناډا د اټومي خوندیتوب کمیسیون [CNSC])، انګلستان (د اټومي مقرراتو دفتر [ONR])، او په نړیواله کچه (IAEA)، سوداګریز اټومي بریښنا فابریکې دوه متمرکز بیړني زون فعالیت کوي:

  • د 16-کیلومتره (10-مایل) د Plume Exposure Pathway EPZ: د دې لپاره ډیزاین شوی چې اوسیدونکي د مستقیم بهرني ګاما افشا کیدو او د هوا له لارې رادیو اکټیو د تنفس څخه خوندي کړي. د 16-کیلو مترو (10-میل) ریډیس دننه اوسیدونکي مخکې توزیع شوي پوتاشیم آیوډیډ ترلاسه کوي (KI) ټابلیټونه، د ځانګړي ټون خبرتیا راډیوګانې، او د رنګ کوډ شوي سکټور د وتلو نقشې.
  • د 80-کیلومتره (50-مایل) د انزال د اکتشاف لاره EPZ: د خوشې کیدو وروسته په ورځو او اونیو کې د رادیو اکټیو د رادیو اکټیو له مینځه وړلو څخه د خواړو او اوبو رسولو خوندي کولو لپاره ډیزاین شوی (د ځایی پاڼي لرونکو باغونو سبزیجاتو مصرف منع کول، څړځای شوي لبنیاتو شیدو او د خلاصې سطحې اوبه).
  • د 4 NRC اټومي اضطراري طبقه بندي (له ټیټ څخه تر لوړ):
  • ** د غیر معمولي پیښې خبرتیا (NOUE): د نبات کوچنۍ بې نظمۍ؛ صفر خوشې کول هیڅ عامه اقدام ته اړتیا نشته.
  • خبرداری: د نباتاتو خوندیتوب تخریب؛ په ساحه کې د وړانګو احتمالي بدلون؛ بیړني عمله په تیاره کې ځای پر ځای شوي؛ هیڅ عامه اقدام ته اړتیا نشته.
  • ** د ساحې بیړني حالت (SAE): د نباتاتو د خوندیتوب دندو لویه ناکامي؛ د احتمالي وړانګو خوشې کول د فدرالي سایټ په حدودو کې ساتل کیږي؛ عامه سایرن کیدای شي د 16-km (10-mile) EPZ دننه غږ شي ترڅو د بیړني خبرتیا سیسټم (EAS) نشراتو ته غوږ ونیسي، او ښوونځي / روغتونونه د احتیاطي حرکت لپاره چمتو کوي.
  • عمومي اضطراري حالت (په لوړه کچه): اصلي یا نږدې د پام وړ اصلي تخریب یا د کنټینټ بشپړتیا احتمالي ضایع کیدو سره. عامه سایرن په دوامداره توګه غږیږي؛ چارواکي سمدستي د په ځای کې د پناه ځای یا د سکټور ځانګړي ویستل امر کوي، او اوسیدونکو ته لارښوونه کوي چې پوتاشیم آیوډیډ واخلي.KI) که I-131 موجود دی

مرحله 2: د ګاما محافظت فزیک او د 7:10 د ضایع کیدو قاعده

که چیرې اټومي چاودنه یا د ریکټور سخت کنټرول سرغړونه د راډیو اکټیو جریان خپروي، نو د خړوب شوي کثافات او انحطاط محصولات اتموسفیر ته لیږدول کیږي او د پیښې وروسته د 10 څخه تر 15 دقیقو ** د ښې شګې یا ایش په څیر بیرته ځمکې ته راښکته کیږي. ځکه چې فال آوټ ستاسو له ودانۍ بهر دوه افقي سطحې پوښي، د ودانۍ شاوخوا ځمکه/کوڅې او ستاسو په سر مستقیم چت، ستاسو هدف دا دی چې د امکان تر حده د خپل ځان او د چت او بهرنۍ ځمکې تر منځ څومره **فزیکي فاصله او کثافت ډله ** وساتئ.

نیمه ضخامت (TVL / HVLد پرتله کولو جدول

In radiation physics, one Halving-Thickness (Half-Value Layer) is the exact thickness of a material required to cut incoming gamma radiation intensity in half (50% reduction). Stacking multiple halving-thicknesses reduces radiation exponentially (10 Halving-Thicknesses = 99.9% reduction):

Shielding Material or Building Location 1 Halving-Thickness (50% Gamma Reduction) 1 Tenth-Thickness (90% Gamma Reduction) Typical Overall Protection Factor (PF) & Survival Assessment
Inside a Passenger Car or Bus Negligible (sheet metal) Negligible PF 1.1 to 1.5 (Almost Zero Protection): Never shelter inside a car; abandon vehicles and enter a heavy building or underground garage.
1-Story Wood-Frame House (Ground Floor) ~28 cm (11 inches) of solid wood ~91 cm (36 inches) of wood PF 2 (Reduces dose by 50%): Poor shielding; gamma rays shine straight through drywall and roof shingles.
Residential Basement (Below Grade, Wood House Above) 9 cm (3.6 inches) of packed earth 30 cm (12 inches) of packed earth PF 10 to 20 (Reduces dose by 90% to 95%): Surrounding earth blocks ground fallout; pile heavy books, water jugs, or soil against ceiling/windows above to block roof rays.
Concrete / Masonry Commercial Basement or Subway 6 cm (2.4 inches) of solid concrete 20 cm (8 inches) of solid concrete PF 50 to 200+ (Reduces dose by 98% to 99.5%): Optimal fallout shelter; thick concrete floor slabs above block roof fallout completely.
Middle Floors of a 10+ Story Concrete High-Rise (Interior Core) 6 cm (2.4 inches) concrete per floor slab 20 cm (8 inches) concrete PF 50 to 100+ (Reduces dose by 98% to 99%): Stay in interior hallways/restrooms at least 3 floors below the top roof and at least 2 to 3 floors above the street.
Water / Packed Books / Concrete Blocks (Improvised Trench) 18 cm (7.2 inches) of water / 9 cm (3.6 in) earth 61 cm (24 inches) of water PF 20 to 50: If your house has no basement, build an improvised "den" under a heavy dining table in the center of the house stacked on all sides and top with water cases, encyclopedia boxes, brick pavers, or bags of potting soil.

How to apply the 7:10 Rule of Fallout Decay (Time)

Fission products in nuclear fallout are intensely radioactive at first because unstable short-lived isotopes decay rapidly. Fortunately, that rapid decay means outdoor radiation levels drop dramatically over the first 48 hours according to the 7:10 Rule of Thumb:

For every 7-fold increase in time after a nuclear burst, the outdoor fallout radiation dose rate decreases by a factor of 10.

  • At T + 1 Hour (Reference peak fallout baseline): 100% dose rate (for example, an immediately lethal 1,000 Roentgens/hour [10 Sieverts/hour] outdoors).
  • At T + 7 Hours (\(1 \times 7\)): Dose rate drops by 10x to 10% (100 R/hr, still dangerous outdoors, stay inside).
  • At T + 49 Hours (~2 Days) (\(7 \times 7\)): Dose rate drops by 100x to 1% (10 R/hr, 99% of the initial gamma intensity is gone, allowing brief emergency evacuations along monitored corridors).
  • At T + 343 Hours (~14 Days / 2 Weeks) (\(49 \times 7\)): Dose rate drops by 1,000x to 0.1% (1 R/hr).

Practical takeaway: Never leave a basement or concrete fallout shelter during the first 24 to 48 hours to look for family or supplies unless your building is actively on fire or collapsing. Stepping outside for just 30 minutes during Hour 2 can deliver a higher total radiation dose than staying inside your basement for the next two weeks combined.


Phase 3: Potassium Iodide (KI), Exact dosing by age, mechanism, and deadly myths

During a nuclear power plant core accident or nuclear fission explosion, one of the primary volatile isotopes released into the plume is Radioactive Iodine (Iodine-131 یا I-131). When inhaled or swallowed via contaminated milk or water, I-131 is rapidly absorbed by the human thyroid gland (which uses iodine to synthesize metabolic hormones), especially in infants, children, and developing fetuses, leading to thyroid destruction and pediatric thyroid cancer years later.

How Potassium Iodide (KI) works (and what it DOES NOT do)

  • Mechanism of Action (Thyroid Saturation): Taking a pharmaceutical dose of stable, non-radioactive Potassium Iodide (KI) floods and saturates the thyroid gland with clean iodine for 24 hours. Because the thyroid is already 100 percent full, any radioactive I-131 you subsequently inhale cannot bind to the thyroid and is harmlessly excreted in your urine.
  • Optimal Timing Window: KI is most effective when taken 1 to 6 hours BEFORE or immediately upon exposure to a radioactive iodine plume. Taken 4 hours AFTER exposure, effectiveness drops to roughly 50 percent; taken 24 hours AFTER a single exposure, KI offers virtually zero benefit (and can actually prolong retention of I-131 already absorbed).
  • What KI DOES NOT do:
  • KI is NOT a general "anti-radiation pill."
  • KI offers zero protection against external gamma radiation.
  • KI offers zero protection to any organ other than the thyroid gland.
  • KI offers zero protection against any radioactive isotope other than Radioactive Iodine (it does nothing against Cesium-137, Strontium-90, Plutonium-239, Cobalt-60، یا Americium-241, meaning KI is useless during most industrial "dirty bomb" incidents that do not involve nuclear reactor fuel).

Official FDA / WHO Potassium Iodide (KI) 24-hour dosage table by age

FDA-approved over-the-counter Potassium Iodide tablets (such as Iosat, ThyroSafe, or liquid ThyroShield) come in 130 mg or 65 mg scored tablets (equivalent to 100 mg or 50 mg of elemental iodine). Administer one single dose every 24 hours only while official public health orders remain in effect:

Age & Physiological Group Threshold Thyroid Exposure (cGy / rem) Daily KI Dose (mg) Number of 130 mg Tablets Number of 65 mg Tablets Crushing & Mixing Notes for Infants/Toddlers
Newborns from Birth to 1 Month \(\ge 5\text{ cGy}\) (Highest Priority) 16 mg (16.25 mg) ⅛ tablet ¼ tablet Crush tablet into fine powder and dissolve precisely in breast milk, formula, or water; administer single dose only (monitor neonatal thyroid closely).
Infants & Toddlers (1 Month to 3 Years) \(\ge 5\text{ cGy}\) (Highest Priority) 32 mg (32.5 mg) ¼ tablet ½ tablet Crush and mix into 1 teaspoon of raspberry syrup, chocolate milk, formula, or applesauce to mask salty/metallic taste.
Children (3 Years to 18 Years) (under 68 kg / 150 lbs) \(\ge 5\text{ cGy}\) (High Priority) 65 mg ½ tablet 1 full tablet Adolescents weighing 68 kg (150 pounds) or more should take the full adult 130 mg dose regardless of age.
Pregnant or Breastfeeding Women (All Ages) \(\ge 5\text{ cGy}\) (High Priority) 130 mg 1 full tablet 2 tablets Protects both maternal and fetal thyroid; repeat doses should be minimized unless evacuation is impossible.
Adults (18 to 40 Years) \(\ge 10\text{ cGy}\) (Moderate Priority) 130 mg 1 full tablet 2 tablets Take once every 24 hours as directed by public health authorities until plume threat ends.
Adults Over 40 Years of Age \(\ge 500\text{ cGy}\) (5 Gy) 130 mg (Only if extreme dose \(\ge 5\text{ Gy}\)) 1 full tablet 2 tablets Adults over 40 have the lowest biological risk of radiation-induced thyroid cancer and the highest risk of KI-induced hyperthyroidism/cardiac side effects; routine KI is not recommended unless exposure threatens complete thyroid ablation (\(\ge 5\text{ Gy}\)).

Never swallow Betadine antiseptic, Lugol solution in random drops, or cups of iodized table salt

During nuclear scares, poison control centers are flooded with overdoses from two deadly myths: 1. Iodized Table Salt: Table salt contains only trace micrograms of iodine (~45 mcg per gram). To get a single 130 mg thyroid-blocking dose of potassium iodide, a person would have to swallow nearly 3 kilograms (6.6 pounds) of table salt at once, which causes fatal hypernatremic brain swelling, seizures, and cardiac arrest long before protecting the thyroid. 2. Topical Povidone-Iodine (Betadine): Never drink brown topical antiseptic solutions or paint them on skin to block radiation; they contain toxic detergents and non-absorbable complexes that cause severe gastrointestinal burns and renal failure.


Phase 4: Step-by-step radiation decontamination (People, Pets, Food, and Water)

Unlike chemical warfare nerve agents that absorb rapidly through intact skin to kill within minutes, radioactive fallout dust sitting on intact skin does not cause instant systemic poisoning, it acts like tiny grains of glowing hot sand emitting beta and gamma rays until washed away.

د شخصي او کورنۍ د پاکولو چک لیست

  1. Remove outer clothing outside or in the mudroom (90% reduction):
  2. Take off coats, hats, shirts, pants, socks, and shoes carefully without shaking the fabric (shaking creates an inhalable dust cloud).
  3. Place the clothing inside a heavy plastic bag, tie it shut, seal it inside a second bag, label it, and store it in the far corner of the garage or outdoors away from human living areas (even if it is radioactive, placing it 5 to 10 meters [16 to 33 feet] away behind a wall reduces its gamma dose to near zero through the Inverse Square Law of Distance).
  4. Shower or wet-wipe skin, hair, and body folds:
  5. If running tap water is available (municipal water inside underground pipes remains safe to wash with during the initial hours), take a warm shower using mild soap and plain shampoo with NO conditioner.
  6. Gently wash hair while leaning forward so rinse water does not run across your eyes and mouth.
  7. Gently blow your nose, wipe your eyelids and eyelashes with a damp clean tissue, and swab your outer ear canals with damp cotton swabs to remove trapped dust.
  8. If tap water is cut off: Use wet baby wipes, damp paper towels, or a clean cloth moistened with bottled water to wipe hair, face, neck, hands, and exposed skin thoroughly, then put on clean clothes stored inside a closed closet or drawer.
  9. Food and water safety rules inside the shelter:
  10. What is 100% SAFE to eat and drink: Any food or beverage that was inside a sealed can, bottle, jar, tetrapak, foil pouch, or closed cardboard box inside a cabinet, pantry, or refrigerator. Notice this critical physical distinction: penetrating gamma rays passing through a closed can of soup or bottle of water do NOT make the food or water radioactive (just as a medical X-ray does not make your body glow). Wipe the outside of the can or bottle with a damp soapy cloth before opening it so surface dust does not fall inside, then eat and drink the contents safely.
  11. Reserve your hot water heater and toilet cistern tanks: Your residential hot water heater tank holds 115 to 300 liters (30 to 80 gallons) of clean, uncontaminated potable water shielded inside a steel jacket, and your toilet upper flush tank (not the bowl) holds another 6 to 11 liters (1.5 to 3 gallons) of clean water (provided you have not used chemical blue drop-in cleaners). Turn off the main street water inlet valve to your house if a municipal surface-water contamination notice is issued so outdoor reservoir water does not flow into your hot water tank.
  12. What is UNSAFE to consume: Uncovered food sitting on counters, open garden produce, berries, leafy greens, and local pasture milk. Note that boiling tap water does NOT remove radioactive isotopes, in fact, boiling evaporates pure steam and concentrates heavy radioactive salts (Cs-137, Sr-90, I-131) in the remaining water (only reverse osmosis, distillation, or ion-exchange/activated carbon filtration removes dissolved radionuclides).

Phase 5: Recognizing Acute Radiation Syndrome (ARS) vs. psychological anxiety

During a radiological emergency, intense fear frequently causes psychosomatic nausea, hyperventilation, tachycardia, and trembling among people who received zero or negligible radiation exposure. Understanding the clinical timeline of Acute Radiation Syndrome (ARS) helps separate anxiety from true medical radiation injury:

  • Threshold Dose for ARS: Acute Radiation Syndrome only occurs when a person receives a high, penetrating whole-body dose exceeding 0.7 to 1.0 Gray (70 to 100 rads / 700 to 1,000 millisieverts) within a short period (equivalent to roughly 100 abdominal CT scans all at once).
  • Time to Vomiting (The Clinical Triage Clock):
  • If a person begins vomiting within 30 minutes to 2 hours after a confirmed high-exposure nuclear event (accompanied by fever, diarrhea, or headache), it indicates a severe whole-body dose (> 2 to 4 Gray) requiring immediate specialized hospital hematologic care (cytokine therapy such as filgrastim/Neupogen to stimulate bone marrow recovery).
  • If a person experiences mild nausea or anxiety with no vomiting after 4 to 6 hours, or was sheltered indoors outside the immediate blast/core zone, life-threatening Acute Radiation Syndrome is extremely unlikely.
  • Reporting to a Community Reception Center (CRC): When authorities open evacuation corridors, drive to a designated Community Reception Center (CRC) (or Emergency Reception Centre), where public health physicists will scan your family from head to toe using portal monitors and pancake Geiger-Mueller counters, verify decontamination, log your geospatial dose registry, and issue potassium iodide or Prussian Blue decorporation therapy if indicated.

Why should we go to an underground basement during a nuclear fallout alert when chemical gas guides say to go to the top floor?

Because chemical gases and nuclear radiation obey completely different physical laws. Most hazardous industrial gases (like chlorine or vinyl chloride) are heavy vapors that flow downhill and collect inside basements, whereas a wooden house upper floor blocks the gas if sealed with plastic. In contrast, nuclear fallout emits high-energy gamma rays that shine straight through wooden walls and roof shingles like X-rays. Because fallout dust coats your roof and the surrounding lawn, an underground basement places thick packed earth and concrete between you and the outdoor radiation, blocking 90 percent to 99 percent of gamma rays.

Why must you never use hair conditioner or "2-in-1" conditioning shampoo when washing off radioactive dust?

Hair conditioners and 2-in-1 moisturizing shampoos contain cationic (positively charged) polymers, quaternary ammonium compounds, and oils engineered to bind tightly to damaged keratin scales on human hair shafts. If you have microscopic radioactive fallout dust in your hair and apply conditioner, those conditioning polymers chemically glue and trap the radioactive particles onto your hair and scalp so water cannot rinse them out. Always wash with plain liquid dish soap, baby shampoo, or basic clarifying shampoo with zero conditioning agents.

Should I take Potassium Iodide (KI) pills right away during any radiation emergency or "dirty bomb" alert?

No, only take Potassium Iodide (KI) when public health or emergency management officials explicitly instruct your geographic zone to do so. KI is not a general anti-radiation shield; it only blocks a single radioactive element, Radioactive Iodine (I-131), from entering a single organ, your thyroid gland. Radioactive iodine is produced only inside nuclear power plant reactors and nuclear weapon explosions. An industrial radiological dispersal device ("dirty bomb") almost always uses Cesium-137, Cobalt-60, Ir-192, or Americium-241, against which Potassium Iodide provides zero protection while still carrying risks of allergic reaction or thyroid dysfunction.

If canned food or bottled water is exposed to gamma radiation during a nuclear event, does the food inside become radioactive?

No. Gamma rays passing through sealed cans, glass jars, or plastic water bottles do not make the food or water inside radioactive, just as getting a medical chest X-ray does not make your body radioactive. As long as the container remained tightly sealed so physical fallout dust could not fall inside, the food and water inside are 100 percent safe to consume. Simply wipe down the outside of the can, lid, or bottle with a damp soapy paper towel before opening it so surface dust does not transfer onto the contents.

Can I boil tap water to remove radioactive contamination after a nuclear release?

Never boil water to remove radiation. Boiling kills biological pathogens like bacteria and viruses, but radioactive elements are heavy chemical isotopes, they do not die when heated. In fact, boiling contaminated water evaporates pure water vapor into your kitchen air while concentrating the radioactive isotopes at an even higher density in the remaining pot of water. Instead, drink bottled water or tap the clean, uncontaminated water stored inside your home 150-to-300-liter (40-to-80-gallon) hot water heater tank after shutting off the main street water inlet valve.

What is the "7:10 Rule" of nuclear fallout, and how long do we have to stay inside our basement shelter?

The 7:10 Rule states that after a nuclear fallout event, for every 7-fold increase in time, the outdoor radiation dose rate drops by a factor of 10 due to the rapid decay of unstable short-lived isotopes. Compared to the radiation intensity at 1 hour after the burst (100 percent), at 7 hours the outdoor radiation drops to 10 percent, and at 49 hours (roughly 2 days) it drops to just 1 percent of its initial level. Because 99 percent of the intense gamma danger disappears within the first 48 hours, staying inside a basement or concrete shelter for the first 24 to 48 hours is the single most important life-saving action you can take.
