Abstract
A workshop was held to determine the optimal use of censored or nondetectable radiation monitoring data in epidemiological studies of radiation exposed workers. Methods of interpreting results from radiation dosimeter and bioassay measurements which had been recorded as zero or adjusted according to administrative practices were discussed. Issues considered in the workshop included changes in dosimeters and detection limits over time, identification and separation of true zero dose results from true positive results, impact of dosimeter exchange frequency on measurement sensitivity, imputation strategies, site specific practices, methods for analyzing different radionuclides, identification of true zero results from censored results, change in sensitivity of method over time, changes in sampling methods over time, quantitative versus qualitative methods, and effects of sampling frequency.
