Industrial & Specialty Applications
Nuclear density gauges are widely used in industrial applications. In some instances, their radioactive sources can be several millicuries (several megabecquerels). Handling density gauges is only for specially licensed individuals. Work should only be performed in the vicinity of these gauges by trained occupational radiation workers. We conduct comprehensive radiation surveys to evaluate dose rates, contamination potential, and safe operating conditions associated with nuclear density gauges. Using calibrated instrumentation and established health physics methods, we verify that equipment is functioning properly and that exposure levels remain within regulatory limits. Our detailed reviews include verification of applicable documentation, gauge accountability, leak test records, personnel dosimetry, radiation protection program policies and procedures, and license conditions.
