TeachMeFinance.com - explain Occupational Dose Occupational Dose The term 'Occupational Dose' as it applies to the area of nuclear science can be defined as ' The internal and external dose of ionizing radiation received by workers in the course of employment in such areas as fuel cycle facilities, industrial radiography, nuclear medicine, and nuclear power plants. These workers are exposed to varying amounts of radiation, depending on their jobs and the sources with which they work. The NRC requires its licensees to limit occupational exposure to 5,000 mrem (50 mSv) per year. Occupational dose does not include the dose received from natural background sources, doses received as a medical patient or participant in medical research programs, or 'second-hand doses' received through exposure to individuals treated with radioactive materials. For additional detail, see Information for Radiation Workers and Measuring Radation. '.
