Abstract
Naturally occurring radioactive materials are most frequently composed of the long-lived radioactive series beginning with uranium and thorium. These elements are unstable and undergo radioactive decay that results in other radioactive elements. This chapter outlines some simple procedures that assist in identifying radiological hazards in a hazardous waste site and in minimizing the health hazards to workers in the area. The risk from radiation exposure is directly proportional to the radiation dose. The actions taken for individual protection against chemical hazards are all appropriate for protection against radiation hazards. The awareness of potential radiological hazardous at any hazardous waste site is essential. Most of the actions taken for protection from chemical hazards are appropriate for the chemical hazards and the extension of the protective actions necessary for protection from the radiological hazards are not difficult. Identification of a severe radiological hazard is simple and the initial evaluation of any site should include radiological screening.
