Exposures to the extremities have increased due to new therapeutic protocols involving beta sources. In this study, thermoluminescent dosimeters based on alpha-Al(2)O(3):C were used to map the dose distribution to the extremities of physicians and paramedical personnel handling beta emitters. The results showed a strong inhomogeneous dose distribution between different phalanxes, fingers and hands of all the investigated subjects, without an indication of systematic trends in the dose patterns. Consequently, conventional dosimetric practices, based on the use of wrist or ring dosimeters, may be not suitable for providing reliable assessments of the inhomogeneous doses received at the fingertip.
由于涉及β源的新治疗方案，四肢的照射量增加了。在这项研究中，使用基于α-Al(2)O(3):C 的热释光剂量计来绘制处理β发射器的医生和辅助医务人员四肢的剂量分布。结果表明，在所研究的所有受试者的不同指节、手指和手部之间存在强烈的不均匀剂量分布，没有剂量模式的系统趋势的迹象。因此，基于使用腕部或指环剂量计的传统剂量学实践可能不适合提供对手指尖不均匀剂量的可靠评估。
