目前由MIRD委员会和ICRP提供的放射性核素的辐射谱不包括非常低能量的N-和O-壳层俄歇电子。这些电子由放射性核素通过电子俘获和/或内部转换衰变而大量发射，对于确定微观体积中的吸收剂量非常重要。因此，本AAPM报告采用Monte Carlo计算方法获得了各种放射性核素（包括Fe-55、Ga-67、Tc-99 m、In-111、In-113 m、In-115 m、I-123、I-125、Pt-195 m、Pt-195 m、Ti-201和Pb-203）的一组自洽的完整辐射光谱。尽管MIRD和ICRP提供的常规光谱足以用于大多数剂量学计算，但推荐使用本报告中提供的俄歇电子光谱来计算直径< 1 μ m的靶体积的剂量。
Radiation spectra for radionuclides currently provided by the MIRD Committee and ICRP do not include the very low-energy N- and O-shell Auger electrons. These electrons, emitted in large numbers by radionuclides decaying by electron capture and/or internal conversion, are important for determining the absorbed dose in microscopic volumes. Accordingly, the present AAPM Report employs Monte Carlo computational methods to obtain a self-consistent set of complete radiation spectra for a variety of radionuclides including Fe-55, Ga-67, Tc-99m, In-111, In-113m, In-115m, I-123, I-125, Pt-195m, Pt-195m, Ti-201, and Pb-203. Although the conventional spectra provided by MIRD and ICRP are adequate for most dosimetry calculations, the Auger electron spectra provided in this report are recommended for calculating the dose to target volumes < 1 mum in diameter.
