In the implementation of a large-scale dosimetry intercomparison one of the main constraints is the availability of large number of dosemeters of the highest quality. Therefore, ISS tested the possibility of using commercially available dosemeters, alanine pellets and thermoluminescence (TL) dosimetry chips, for transfer dosimetry within the Italian intercomparison programme. In this work the characterisation of commercial alanine and TL dosemeters along with the ISS dose assessment procedure used in the Italian intercomparison are reported. Results demonstrate the feasibility of the ISS approach to transfer dosimetry since it is possible to measure 10 Gy with a combined uncertainty of 1% (1sigma) and 1 Gy with a combined uncertainty of 1.7% (1sigma) with alanine and TL dosemeters, respectively.
在开展大规模剂量测定比对工作时，主要限制因素之一是能否获得大量最高质量的剂量仪。因此，意大利空间局（ISS）在意大利比对计划中测试了使用市售剂量仪、丙氨酸颗粒和热释光（TL）剂量测定芯片进行传递剂量测定的可能性。本文报道了市售丙氨酸和热释光剂量仪的特性以及意大利比对中使用的意大利空间局剂量评估程序。结果表明，意大利空间局的传递剂量测定方法是可行的，因为使用丙氨酸和热释光剂量仪分别可以测量10 Gy，合成不确定度为1%（1σ），测量1 Gy，合成不确定度为1.7%（1σ）。
