Differential Dosimetry in a Neutron-Proton Mixed Field with Low-Pressure Proportional Counters
Abstract
Abstract For a mixed radiation field of neutrons and protons, radiation events were discriminated between photons, neutrons, and protons using a thin plastic scintillator. Distributions of lineal energy were measured with low-pressure proportional counters (LPPCs). To estimate the distribution of lineal energy for ICRU muscle, measurements were carried out using A-150-walled, graphite-walled, ZrO 2 -walled, and Zr-walled counters. Data were corrected for different atomic compositions between the A-150 plastic and ICRU muscle. Radiation Protection Dosimetry
