Radiat Prot Dosimetry. 2017 Apr 20;174(1):6-12. doi: 10.1093/rpd/ncw051.
An intercomparison of eye lens dosemeters has been conducted in terms of the quantity Hp(3). For the first time, besides photon radiation also beta radiation qualities were included. Three dosemeter types designed for the quantity Hp(3) and ten for Hp(0.07) took part in the intercomparison. As shown in a previous intercomparison for photon radiation only, the dosemeters designed for Hp(0.07) and calibrated in terms of Hp(3) performed well in photon radiation fields. But for beta radiation, it turned out that Hp(0.07) dosemeters over-responded up to a factor of 5 000 (with respect to the true Hp(3) dose) in the medium beta energy range (85Kr with a beta endpoint energy of 0.69 MeV), while some Hp(3) dosemeters performed quite well. For medium (57 keV) and high (662 keV) energy photon radiation, all dosemeter types showed response values well within the trumpet curve according to the current draft of ISO 14146.
已经根据Hp(3)量对眼晶状体剂量计进行了比对。除了光子辐射外，首次还纳入了β辐射品质。三种为Hp(3)量设计的剂量计类型和十种为Hp(0.07)量设计的剂量计参与了此次比对。如之前仅针对光子辐射的比对所示，为Hp(0.07)设计并按Hp(3)校准的剂量计在光子辐射场中表现良好。但对于β辐射，结果表明，在中等β能量范围（85Kr，β终点能量为0.69 MeV），Hp(0.07)剂量计的响应高达真实Hp(3)剂量的5000倍，而一些Hp(3)剂量计表现相当不错。对于中等能量（57 keV）和高能量（662 keV）的光子辐射，根据ISO 14146的当前草案，所有剂量计类型的响应值均在喇叭曲线范围内。
