本文叙述了定向辐射取样方法的基本原理。提出了应用等效定向铅屏改善定向辐射仪定向性的可能性。设计了既可用于定向辐射取样又可用于炮孔γ测量的新型两用探测器并对它的主要性能参数进行了测定。现场试验结果表明,这种新的定向探测器能起到“一机两用”的作用。
This paper describes the basic principles of directional radiation sampling method. The possibility of using the equivalent orientation lead screen to improve the directivity of the directional radiometer is proposed. A novel dual-purpose detector that can be used both for directional radiation sampling and gunhole γ measurement was designed and its main performance parameters were measured. Field test results show that this new directional detector can play a “dual-use” role.
