Can you survive nuclear fallout? - Brooke Buddemeier and Jessica S. Wieder

Explore the possibility of surviving a nuclear explosion and dig into a scientifically supported plan of action in case of a detonation.



Nuclear weapons are some of the most powerful tools of destruction on Earth, and the full scope of a nuclear detonation is almost unimaginable. However, there is a scientifically supported plan of action that could save thousands of lives. What is this plan, and what exactly would it protect us from? Brooke Buddemeier and Jessica S. Wieder explore the possibility of surviving nuclear detonation.

6.836 -> The full scope of a nuclear detonation is almost unimaginable.
11.726 -> Hopefully, no one will ever experience another of these catastrophic incidents.
16.726 -> But there is a scientifically supported plan of action
20.621 -> that could save hundreds of thousands of lives
22.931 -> in the area surrounding a nuclear explosion.
25.911 -> So what is this plan,
27.411 -> and what exactly would it protect us from?
30.241 -> To create their destructive blast,
32.491 -> these weapons harness the power of nuclear fission–
35.951 -> in which an atom’s nucleus is split in two.
39.431 -> This process produces an incredible amount of energy,
42.871 -> and in some materials the neutrons produced by one fission
46.871 -> are absorbed by nearby atoms,
49.331 -> splitting additional nuclei.
51.581 -> These chain reactions can produce a range of explosive yields,
55.641 -> but let’s consider an explosion equivalent to 10,000 tons of TNT.
61.147 -> An explosion like this would create
62.997 -> a fireball capable of decimating a few city blocks
66.777 -> and a shockwave damaging buildings several kilometers away.
70.877 -> There is tragically nothing that can be done
72.998 -> to save those in the fireball’s radius.
75.938 -> However, for those in the shockwave and beyond,
79.347 -> our scientifically supported protocol could be life saving.
83.357 -> And though it may sound surprising,
85.297 -> the best way to stay protected before, during, and after a nuclear detonation,
90.567 -> is getting inside.
92.688 -> Similar to protecting yourself from tornadoes or hurricanes,
96.408 -> getting and staying inside a sturdy building would offer protection
100.328 -> from the explosion’s shockwave, heat, and radiation.
103.928 -> The shockwave of energy would travel
105.858 -> several kilometers beyond the fireball’s radius in the first few seconds.
110.708 -> Sturdy buildings within that range should be able to withstand the shockwave,
115.238 -> and staying in the centers and basements of these buildings
118.791 -> also helps provide protection from heat and flying objects.
123.758 -> Finding shelter is especially important if the fireball occurs close to the earth,
128.828 -> as it will pull thousands of tons of dirt and debris
132.29 -> several kilometers into the atmosphere.
135.27 -> As the fireball cools,
137.05 -> unstable atoms created by the nuclear fission mix with the debris
141.6 -> to produce the most dangerous long-term effect of a nuclear detonation:
145.8 -> radioactive particles called fallout.
149.303 -> These sand-sized particles emit ionizing radiation,
153.413 -> capable of separating electrons from molecules and atoms.
157.291 -> Exposure to massive amounts of this radiation can result in cell damage,
161.851 -> radiation burns, radiation sickness, cancer, and even death.
167.058 -> Created several kilometers up,
169.298 -> dangerous concentrations of this material
171.768 -> would be driven by upper atmospheric winds,
174.798 -> potentially leading to hazardous levels of fallout
177.768 -> in areas up to tens of kilometers downwind.
181.738 -> Thankfully, the same buildings that offer protection from the blast
185.466 -> are even better at guarding against fallout.
188.796 -> Radiation is reduced as it travels through space and mass.
192.993 -> So while a broken window and sealed window
195.473 -> both have the same minimal effect on radiation,
198.493 -> thick layers of steel, concrete, and packed earth
202.393 -> can offer serious protection.
204.733 -> And since fallout gives off half of its energy in the first hour
208.562 -> and 80% in the first day,
210.992 -> staying inside for 24 hours could dramatically improve the odds
215.072 -> of avoiding the most serious effects of radiation.
218.752 -> Following the blast there would be at least 15 minutes to find shelter
223.012 -> before the fallout begins.
225.092 -> Since the most hazardous fallout particles are the heaviest,
228.432 -> they sink through the air
229.962 -> and collect on streets and rooftops,
232.322 -> making ideal shelters underground or in the middle of high-rise buildings.
237.842 -> But if someone were to get caught in the fallout,
240.562 -> there are still measures they could take.
242.842 -> After finding a safe space,
244.472 -> they should remove their shoes and outer layers,
247.252 -> wash any exposed skin,
249.092 -> and store the contaminated clothing far away.
252.582 -> Once inside,
253.612 -> plan on staying there for at least 24 hours.
256.522 -> If the shelter is poor, or someone inside needs urgent medical attention,
260.792 -> try seeking outside help after an hour.
264.049 -> But ideally,
264.899 -> stay inside and stay tuned for more information from first responders.
269.909 -> While electric power, cell service, and Internet would be down,
273.712 -> most radios would likely survive.
276.152 -> So listen in for emergency responders
278.612 -> to determine the safest course forward.
281.572 -> Nuclear weapons are some of the most powerful tools of destruction on Earth,
285.652 -> and it may seem naive to put faith in these straightforward protective measures.
289.944 -> But studies and simulations have repeatedly shown the benefits
293.494 -> of getting inside.
295.294 -> So while we’ll hopefully never need to,
297.494 -> remember to Get Inside, Stay Inside, and Stay Tuned.
