Abstract

The radiation dose to radiobiologically critical organs at various anatomic sites in a phantom was compared with the use of rare earth screen/film combinations and calcium tungstate screen/film combinations. Rare earth screens and films produced a reduction in dose up to 40% to 50% depending on the anatomic site.

摘要

使用稀土增感屏/胶片组合和钨酸钙增感屏/胶片组合，比较了体模中不同解剖部位对放射生物学关键器官的辐射剂量。根据解剖部位的不同，稀土增感屏和胶片可使剂量降低40%至50%。
