Dosimetry and Bioassay
Radiation exposures can arise either from radioactive materials that spontaneously emit ionizing radiation or from devices that produce x-rays or other forms of radiation such as electrons or protons. Regulatory agencies require personnel radiation exposures to be maintained as low as is reasonably achievable (ALARA). Determining whether an individual receives a measurable radiation dose requires an effective personnel monitoring program; therefore, the measurement and documentation of personnel radiation doses are essential services offered by RSS. The RSS Dosimetry Program provides state-of-the-art radiation monitoring dosimeters and maintains permanent records of all personnel radiation doses. Dosimeters are currently exchanged at monthly or quarterly intervals. Refer to the Forms link to obtain necessary dosimetry forms. If you have questions regarding radiation monitoring dosimeters, please call 764-4294.

RSS also provides various radio-bioassay services to measure and record the intake of radioactive material resulting from inhalation or ingestion. Internal dosimetry techniques evaluate radioactive material intakes by locating the radionuclide in the body (in vivo) or by analyzing bodily fluids such as urine (in vitro).
