Gamma Shielding by People in the Bomb Shelter

The table in Chapter 3 shows the human body has a density of 0.4 relative to concrete. The shielding effect of human bodies can be used to provide extra protection. This protection would be of particular benefit to those people with the greatest sensitivity to radiation, namely, children and pregnant women. If the estimated or projected radiation exposures look as ... Read More »

Dosimeter Locations

Where could dosimeters be mounted or hung? Are needed materials available for mounting or hanging them? In some bomb shelters where the FPF is high and about the same everywhere, as in deep underground bomb shelters, caves, and mines, only a few dosimeters need to be mounted or hung where people will be located, to get an idea of what ...

While Fallout is Coming Down at the Bomb Shelter: Decontamination of People Caught in Radioactive Fallout

Fallout arriving within a few hours after a nuclear explosion is highly radioactive. If it collects on the skin in large enough quantities it can cause beta burns (see section, “Symptoms of Radiation Injury”). People who are caught outside in fallout should brush fallout particles off themselves and shake out their outer garments as soon as they get inside the ... Read More »

Checking Out the Bomb Shelter

Many different kinds of bomb shelter will be used for protection against fallout in an emergency. Some bomb shelters may be in schools, churches, or banks. Others may be in factories, office buildings, large stores, underground garages, basements of apartments or houses, mines, or caves. Some bomb shelters may have many rooms, some of them on different levels, and others ... Read More »

Best Bomb Shelter Protection

Which locations within the bomb shelter appear to offer the best protection against fallout? Sketch a bomb shelter floor plan and mark these locations. The best protection is provided by getting as much mass as possible between you and the fallout. Walk through the bomb shelter and get an idea where the best protected areas might be. Usually, but not ... Read More »

Understanding Radiation: Radiation and Fallout

Fallout is simply the dirt and dust which falls to the ground following a nuclear explosion. It will “charged” with radiation and will eventually “burn” itself out – a process that will take several days. Radioactive fallout will fall in a manner similar to that following a volcanic eruption. It will be flaky in appearance and its size may reduce ... Read More »
