In 2012, the International Commission on Radiological Protection issued a recommendation for a reduced annual eye-lens dose limit in the face of mounting evidence of the risk of cataract induction. This led to worldwide research efforts in various areas including the dose simulation in realistic eye-models, the production of dosimeters and the elaboration of protection and operation fluence to eye-lens dose coefficients. In this last case, much efforts have been expanded with regards to photon operational coefficients for Hp (3) but much less for electron radiation. In this work, Hp (3) coefficients for electrons are presented following simulations using MCNP and compared to those that are available in the literature. It is found that, at energies of 1 MeV and less, Hp (3) coefficients depend strongly on the selected electron transport options and on the dose tally volume. The effect of these differences is demonstrated for two beta emitters.

电子眼镜操作剂量系数。

2012 年，面对越来越多的白内障诱发风险的证据，国际放射防护委员会发布了一项建议，要求降低每年的晶状体剂量限制。这导致了世界范围内各个领域的研究工作，包括真实眼模型中的剂量模拟、剂量计的生产以及对眼睛晶状体剂量系数的保护和操作影响的详细说明。在最后一种情况下，在 Hp (3) 的光子操作系数方面已经做了很多努力，但在电子辐射方面则少得多。在这项工作中，电子的 Hp (3) 系数在使用 MCNP 进行模拟后呈现，并与文献中可用的系数进行比较。发现在 1 MeV 及以下的能量下，Hp (3) 系数很大程度上取决于所选的电子传输选项和剂量计数体积。两个β发射器证明了这些差异的影响。
