ABSTRACT:
An irradiator is disclosed for irradiating dosimeters type used to monitor environmental exposure or exposure of personnel to radiation. The irradiated dosimeters are used as standards against which dosimetry analysis equipment is calibrated. The invention provides an improved design for an irradiator which permits uniform irradiation of dosimeters over a wide range of radiation doses and which can provide both primary and secondary standards for calibration purposes. The irradiator includes a shielded housing designed with an optimum geometry to ensure uniform dosage across the face of the dosimeter, a filter to prevent undesirable scattered radiation from reaching the dosimeter during exposure, and a movable radiation attenuator to permit large differences in desired dose to be easily accommodated.
