Conversion coefficients were calculated for fluence-to-absorbed dose, fluence-to-equivalent dose, fluence-to-effective dose and fluence-to-gray equivalent for isotropic exposure of an adult female and an adult male to tritons ((3)H(+)) in the energy range of 10 MeV to 1 TeV (0.01-1000 GeV). Coefficients were calculated using Monte Carlo transport code MCNPX 2.7.C and BodyBuilder™ 1.3 anthropomorphic phantoms. Phantoms were modified to allow calculation of effective dose to a Reference Person using tissues and tissue weighting factors from 1990 and 2007 recommendations of the International Commission on Radiological Protection (ICRP) and calculation of gray equivalent to selected tissues as recommended by the National Council on Radiation Protection and Measurements. At 15 of the 19 energies for which coefficients for effective dose were calculated, coefficients based on ICRP 2007 and 1990 recommendations differed by less than 3%. The greatest difference, 43%, occurred at 30 MeV.
计算了成年女性和成年男性在10 MeV至1 TeV（0.01 - 1000 GeV）能量范围内各向同性暴露于氚离子（(3)H(+)）时，注量到吸收剂量、注量到当量剂量、注量到有效剂量以及注量到比释动能当量的转换系数。使用蒙特卡罗输运代码MCNPX 2.7.C和BodyBuilder™ 1.3人体模型计算系数。对人体模型进行了修改，以便根据国际放射防护委员会（ICRP）1990年和2007年建议中的组织和组织权重因子计算参考人的有效剂量，并按照美国国家辐射防护与测量委员会的建议计算选定组织的比释动能当量。在计算有效剂量系数的19种能量中的15种能量下，基于ICRP 2007年和1990年建议的系数差异小于3%。最大差异为43%，出现在30 MeV处。
