| a The number of latent fatal cancers is expected because of exposure to ionizing radiation. The cancer can develop, and
death can occur many years after exposure
b Risk resulting from routine, normal day-to-day operations without accidents or other unexpected or unusual occurrences c For accident risk assessment, inhalation exposure to radioactive or chemical materials is assumed to occur under neutral atmospheric conditions (Pasquill atmospheric stability Class D). This results in most-likely or average exposure d For accident risk assessment, inhalation exposure to radioactive or chemical materials is assumed to occur under stable atmospheric conditions (Pasquill atmospheric stability Class F). This results in worst-case or maximum exposure e The total number of health detriment cases because of exposure to ionizing radiation minus the number of latent fatal cancers. Health detriments include genetic damage and development of nonfatal cancer f The number of fatalities expected to occur a relatively short time (a few days to a few months) after acute radiation exposure. Death occurs because of loss of bone marrow function and, at higher doses, gastrointestinal damage and acute inflammation of the lungs g The number of injuries expected to occur a relatively short time (a few days to a few months) after acute radiation exposure h The number of latent cancers expected because of exposure to a chemical carcinogen. Cancer can develop many years after exposure I Not applicable j The ratio between the daily intake of a noncarcinogenic toxic chemical and acceptable reference level. A hazard index less
than one indicates that exposure would not result in adverse noncarcinogenic health effects.
