本文件规定了ISO中组织等效平板体模吸收剂量率的测量方法？6980参考β粒子辐射场。这些参考辐射所覆盖的发射β粒子的同位素的能量范围是0.22？小姐是3，6？MeV最大β能量对应于0.06？小姐是1，1？MeV意味着β能量。超出该范围的辐射能量超出了本文件的范围。虽然在参考几何形状（深度0.07？mm还是3？组织中垂直入射的mm？等效平板体模）与外推室用作主要标准，但也描述了其他测量系统的使用和其他几何形状中的测量，尽管不太详细。然而，正如ICRU所指出的？56[5]中，用于区域监测的环境剂量当量H*(10)和用于个人监测的个人剂量当量Hp(10)不合适任何β辐射的te量，即使是穿透10？毫米的组织（Emax？>？2？MeV）。本文件适用于那些希望建立β粒子主要剂量测定能力的组织，并作为使用外推室作为β粒子主要标准的剂量测定性能的指南？其他领域的粒子剂量学。还提供了关于测量不确定性陈述的指导。
This document specifies methods for the measurement of the absorbed-dose rate in a tissue-equivalent slab phantom in the ISO 6980 reference beta-particle radiation fields. The energy range of the beta-particle-emitting isotopes covered by these reference radiations is 0,22 MeV to 3,6 MeV maximum beta energy corresponding to 0,06 MeV to 1,1 MeV mean beta energy. Radiation energies outside this range are beyond the scope of this document. While measurements in a reference geometry (depth of 0,07 mm or 3 mm at perpendicular incidence in a tissue？equivalent slab phantom) with an extrapolation chamber used as primary standard are dealt with in detail, the use of other measurement systems and measurements in other geometries are also described, although in less detail. However, as noted in ICRU 56[5], the ambient dose equivalent, H*(10), used for area monitoring, and the personal dose equivalent, Hp(10), as used for individual monitoring, of strongly penetrating radiation, are not appropriate quantities for any beta radiation, even that which penetrates 10 mm of tissue (Emax > 2 MeV).This document is intended for those organizations wishing to establish primary dosimetry capabilities for beta particles and serves as a guide to the performance of dosimetry with an extrapolation chamber used as primary standard for beta？particle dosimetry in other fields. Guidance is also provided on the statement of measurement uncertainties.
