Abstract

The use of a custom-made cylindrical graphite proportional counter (Cy-GPC) along with a cylindrical tissue equivalent proportional counter (TEPC) for neutron-gamma mixed-field dosimetry has been studied in the following steps: first, the consistency of the gamma dose measurement between the Cy-TEPC and the Cy-GPC was investigated over a range of 20 keV (X-ray) to 0.661 MeV (Cs-137 gamma ray). Then, with both the counters used simultaneously, the neutron and gamma ray doses produced by a P385 Neutron Generator (Thermo Fisher Scientific) together with a Cs-137 gamma source were determined.

摘要

已通过以下步骤研究了使用定制的圆柱形石墨正比计数器（Cy-GPC）以及圆柱形组织等效正比计数器（TEPC）进行中子-γ混合场剂量测定：首先，研究了Cy-TEPC和Cy-GPC在20 keV（X射线）至0.661 MeV（Cs-137γ射线）范围内γ剂量测量的一致性。然后，同时使用这两个计数器，测定了P385中子发生器（赛默飞世尔科技公司）与Cs-137γ源一起产生的中子和γ射线剂量。
