摘要：

This paper details the construction of a Cs-137 gamma calibration curve that has been established for dicentric assay and the testing and validation of the curve through biological dosimetry in three situations of suspected workplace overexposure that arose accidentally or through negligence or lack of appropriate safety measures. The three situations were: (1) suspected Cs-137 contamination in a factory air supply; (2) suspected exposure to an industrial Ir-192 source; and (3) accidental exposure of construction workers to radiation from a Co-60 radiotherapy source in a hospital medical physics department. From a total of 24 potentially-exposed subjects, only one worker was found to have a statistically significant dose (0.16 Gy, 95% confidence intervals 0.02-0.43 Gy). In all other cases, the main function of the biological dosimetry was to reassure the subjects that any dose received was low. Health Phys. 98(2):252-257; 2010
