The NIM alanine/ESR dosimetric system, which was designed for industrial radiation processing, has been improved to be suited for applications in therapy dose range. Two different procedures of dose intercomparisons between IAEA and NIM were carried out with the improved system in the range of 2.5 to 100 Gy. In the first procedure, a set of NIM alanine dosimeters were irradiated at IAEA dosimetric laboratory and part of dosimeters marked "for evaluated" were evaluated using the rest of those with "known dose" given by IAEA. Most of evaluated doses agreed with IAEA doses within 1%. In the second procedure, all above dosimeters were evaluated on the base of NIM dosimetry. The results indicated that the doses determined by NIM agreed with those given by IAEA within 3% on the average.
为工业辐射加工设计的NIM丙氨酸/血沉棕黄层剂量测定系统已得到改进，以适用于治疗剂量范围的应用。在2.5至100 Gy范围内，使用改进后的系统对国际原子能机构（IAEA）和NIM之间的剂量进行了两种不同的比对程序。在第一个程序中，一组NIM丙氨酸剂量计在IAEA剂量测定实验室进行辐照，部分标记为“用于评估”的剂量计使用IAEA给出的其余带有“已知剂量”的剂量计进行评估。大多数评估剂量与IAEA剂量的误差在1%以内。在第二个程序中，所有上述剂量计均基于NIM剂量测定法进行评估。结果表明，NIM测定的剂量与IAEA给出的剂量平均误差在3%以内。
