To put this in perspective, the average person in the United States receives an exposure of 300 millirem per year from natural background sources of radiation. Occurs at the instant of the detonation of an IND and ends within a few seconds. It causes electrons to vibrate, thereby generating heat, but it does not have sufficient energy to cause physical harm by removing electrons from atoms. Time, distance, and shielding measures minimize your exposure to radiation in much the same way as they would to protect you against overexposure to the sun (as illustrated in the following figure). They are usually very small; their size can vary from tiny "seeds" used in cancer treatment, to the size of the tip of a ballpoint pen or a pencil eraser, to rods up to several inches in length, depending on the material and its configuration.

How the radiation accumulates depends on the degree of exposure dose and duration and the half-life of the element, said Hei. And it got a big boost yesterday. The nucleus carries a positive electrical charge, while the electrons carry a negative electrical charge. The total radioactivity of the fission products is extremely large at first, but it falls off at a fairly rapid rate as a result of radioactive decay. This eventually led to the worlds first controlled nuclear chain reaction, achieved by Fermi and his group on December 2, 1942, in the squash court under the stands of the universitys Stagg Field. However, the other parts of a compensation package are almost as important. A nuclear explosion produces a complex mix of more than 300 different isotopes of dozens of elements, with half-lifes from fractions of a second to millions of years. An operating nuclear power plant produces very small amounts of radioactive gases and liquids, as well as small amounts of direct radiation. Once in the body whether inhaled or absorbed through gills or other organs radiation can make its way into the bloodstream, lungs, and bony structures, potentially causing death, cancer, or genetic damage.
