The explosion of a nuclear weapon is likely to have immediate adverse effects and devastating long-term impacts on the climate. These weapons are the most terrifying on Earth, as they remain uncertain about the possibilities of survival after their attacks. However, some studies report means of protection against these weapons. In the particularly tense geopolitical context between Russia and Ukraine, we decided to explore this theme.
The effects of a nuclear weapon
Remember, in 1945, the only two atomic bombs used to date were dropped. These were Little Boy about the city of Hiroshima and Fat Man about Nagasaki. With a temperature of 300,000°C, the first wiped Hiroshima off the map. This temperature is 250 times more powerful than that used for incineration of a body. It is therefore impossible to count survivors in the areas surrounding the point of impact.
During its explosion, the nuclear weapon releases a ball of fire whose size depends on its power. Depending on this size, the latter affects its point of impact within a given radius. Among these impacts are:
- The blast effect;
- strong heat;
- The electromagnetic pulse.
Take refuge indoors to survive a nuclear attack
Saving survivors in the deflagration zone of a nuclear bomb is utopian. However, people in the area affected only by the blast of the explosion are more likely to survive. To put all the chances of survival on your side, we recommend that you take shelter inside a solid building. But still it is necessary to remain in the center of the building in its basement. Only in this way will you avoid the heat and objects thrown by the blast of the explosion.
In addition, the shock wave travels several kilometers during the explosion in the space of a few seconds. With this in mind, such a precaution must be taken as soon as possible.
Explosion near the ground
In this case, a large number of debris will be ejected into the atmosphere, not to mention dust with unstable atoms called radioactive fallout. The latter carried by the wind for tens of kilometers can cause burns, nausea, and long-term cancer or even death. By taking shelter in the heart of a building, you put all the chances of survival on your side. For this purpose, experts recommend a building made of steel, concrete or compacted earth.
How long to stay under cover? Simply the time required until the radioactivity drops in the affected area. Thus, after one hour, the radioactive fallout is 50% less dangerous, and 80% after 24 hours. However, we advise you to spend little time outdoors even the day after the explosion. After 15 minutes maximum, go to a shelter.
If you will be outside longer than expected, remove all clothing and shoes before entering the shelter. Get rid of it and clean any parts of your body that may have been exposed to radiation.
