本文主要介绍了我院~(60)Co移动条吸收剂量的测试方法及剂量分布结果。 我们采用法莫(Farmer)2502/3型剂量仪,电离室体积为0.6ml,采用遥控模拟人体组织的水模体,体积为30×30×50cm进行测试移动条各点的吸收剂量。测试中我们认为电离室安放在第一条(2.5×20cm)下各测试点,测量出各条各点的叠积吸收剂量,是正确的。 本文认为,在目前我国尚不能普遍应用热释光剂量计来测试移动条吸收剂量分布时,使用电离室剂量仪在水模中进行测试,是一种有效的方法。
This article mainly introduces the test method and dose distribution of absorbed dose of ~ (60) Co moving strip in our hospital. We use the Farmer 2502/3 dosimeter with an ionization chamber volume of 0.6 ml and a remotely piloted water phantom that simulates human tissue at a volume of 30 × 30 × 50 cm to test the absorbed dose at each point of the moving strip. In the test, we think the ionization chamber is placed at the first test point (2.5 × 20cm), and it is correct to measure the accumulated absorbed dose of each point. In this paper, it is considered that it is an effective method to measure the absorbed dose distribution of moving strips by the common application of thermoluminescence dosimeters in our country.
