Performance Criteria for Environmental Radiation Monitoring with TLD Systems

Guidance to the selection, laboratory evaluation, and application of TLD systems for routine environmental radiation monitoring is presented. Methods are discussed for performing initial and routine evaluations to assure that required accuracy and reliability is achieved and maintained. A typical environmental measurement made with a commercial system is examined to illustrate the effects of the various parameters and techniques considered. Methods for separating total radiation exposure measurements to isolate its components, notably that attributable to the gaseous effluent from a nuclear facility, are discussed.
