Radiological Emergency Management Independent Study Course 1-12 exposures received over an extended period of time can be tolerated by the body with much less biological effect than acute exposures . Biological Factors Although the effects of exposure to large groups can be predicted, each individual's body differs. These differences can mean that, except at extremely high acute doses, two people exposed to the same amount of nuclear radiation may experience different symptoms. Biological factors which may influence the effect of radiation on an individual include age, sex, diet, body temperature, and health. Biological Symptoms The symptoms discussed below are those caused by large short-term (acute) exposures of gamma radiation. We will relate some general symptoms to specific amounts of exposure. These classifications must be general because, as previously stated, radiation effects are somewhat variable among individuals. Two visible, potential signs of radiation sickness are nausea and vomiting. Since shock or pain can also
