摘要

通过测量厚度约为1.6 X 10(-2) kg/m2的liff - teflon圆盘，评估了聚苯乙烯模体中不同尺寸的气腔周围的积聚和积聚情况。测量结果表明，当两束相对照射时，腔(深度39 mm)的表面剂量为60 Co最大剂量的74%，6 MV为77%，42 MV为87%。

Build-up effects at air cavities measured with thin thermoluminescent dosimeters.

The build-up and build-down situation around air cavities of various size in a polystyrene phantom was evaluated by measurements with LiF-Teflon disks with a thickness of about 1.6 X 10(-2) kg/m2. The measurements demonstrate that when irradiating with two opposed beams the surface dose at the cavity (depth 39 mm) is 74% of the maximum dose for 60 Co, 77% for 6 MV and 87% for 42 MV roentgen radiation.
