Description
Summary:The results of measurements of the local irradiation dose to the most highly irradiated sections of the body of a therapy provider -- the skin on the fingers and palm and regions of the chest -- are presented. The measurements were performed by the method of thermoluminescence dosimetry using highly sensitive TLD-500K detectors. It was established that even for the highest total activity of these sources (1221 MBq) and the longest period of work without the use of x-ray protective gloves the maximum dose (minus the natural background and take the account to the energy dependence of the sensitivity of the detector) to the provider is 0.18 c 0.01 mGy (the large finger on the right hand was exposed to the highest irradiation level) and 0.01 c 0.0004 mGy (the outer side of the palm of the left-hand was exposed to the lowest irradiation level), which does not present a radiation hazard even when working repeatedly with the sources.
