摘要

提出了一种用于测量478 keV伽马辐射的新型反符合探测器，用于评价硼中子俘获治疗。通过测量从主探测器散射的小角度康普顿伽马射线，可以有效地抑制目标光峰位置周围的康普顿连续体。使用蒙特卡罗模拟的数值评估估计计数减少了80%，并且开发的原型探测器显示康普顿钴-60伽马射线连续体抑制了4%。

Development of anticoincidence detector specializing in small-angle Compton scattering gamma rays for boron neutron capture therapy

A novel anticoincidence detector is proposed for the measurement of 478 keV gamma radiation for evaluation of boron neutron capture therapy. The Compton continuum around the target photopeak position is effectively suppressed by measuring only the Compton gamma rays scattered at small angles from the primary detector. A numerical evaluation using Monte Carlo simulations estimated an 80% reduction in counts, and the developed prototype detector showed 4% suppression of the Compton continuum of cobalt-60 gamma rays.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
