The relative dose distribution around a 5.0-cm-long piece of 192Ir wire has been measured using LiF chips. Measurements were made at distances of 0.25 to 5.0 cm away from the source and distances of 0.0 to 4.0 cm along the source. In addition, measurements were also made at several distances along the axis of the source. Attention was paid to the errors associated with these measurements. A comparison was made between a commercial software program, ISODOS, an analytical solution to the Sievert integral, and the measurements. Good agreement was obtained at distances along and away from the source. Major disagreements were found at points along the source axis.
使用LiF芯片测量了一根5.0厘米长的192Ir丝周围的相对剂量分布。在距离源0.25至5.0厘米处以及沿源0.0至4.0厘米处进行了测量。此外，还沿源轴在几个距离处进行了测量。对这些测量相关的误差予以了关注。对商业软件程序ISODOS、西弗特积分的解析解和测量结果进行了比较。在沿源和远离源的距离处获得了良好的一致性。在源轴上的点发现了较大差异。
