Features
- Measure the radiation load to hands of persons, e.g., working in interventional radiology or in nuclear medicine
- Accommodate thermoluminescent dosemeters for dose integration
- Require a shrinking tube which can be sterilized using liquids
Although the extremities are less sensitive against radiation exposure, the accumulated dose to hands of persons who have direct contact with ionizing radiation, as common in interventional radiology and in nuclear medicine, may result in high exposure values. The measurement of the radiation load to their hands is essential for radiation protection for those persons. Finger rings accommodating TL detectors serve as dose integrators indicating the total exposure to the hands of operators. To ensure sterile conditions and to protect the finger rings against radioactive contamination, the rings are covered by protective shrinking tubes. The ring model 8632 is made of stainless steel with open ends to adjust the ring diameter mechanically to the required size. Engraved numbers on the rings are used for individual identification. Each radiation protection finger ring accommodates a TLD chip of maximum 4.5 mm diameter for dose integration. To evaluate the TL detectors, a TLD reader is required.
