Unformatted text preview: ground are not considered a serious hazard, since the source is outside the body. However alpha particles are harmful if the alpha-emitting source is taken into the body. The beta radiation which is much less penetrating than gamma radiation, may cause skin burns if the fallout remains on the body surface for a prolonged period of time. Exposure from the gamma radiation is considered the major hazard as a result of fallout. The extent, nature, and arrival time of fallout are difficult to predict accurately due to variables such as: O Energy yield of the weapon--a more powerful bomb will produce more fallout. O Height of explosion--a ground level blast will produce more fallout than an elevated blast....
