The authors present the results of experimental investigations of distribution of capture events on nuclei 10B by the depth of a water phantom during its irradiation with beams T-4 and B-3 of the BR-10 reactor. A ferrous sulfate dosimeter with added boric acid was used as a detector of such events. The depth of a water phantom on which the effect of boron capture by a neutron beam is decreased 2-fold, is 1.7 cm. For the B-3 beam a curve of depth correlation of neutron capture events had a broad maximum at a depth of 4-5 cm.
作者介绍了在BR - 10反应堆的T - 4和B - 3束流照射水模体期间,对硼-10核俘获事件按水模体深度分布进行实验研究的结果。添加硼酸的硫酸亚铁剂量计用作此类事件的探测器。中子束硼俘获效应降低两倍时水模体的深度为1.7厘米。对于B - 3束流,中子俘获事件的深度相关性曲线在4 - 5厘米深度处有一个宽峰。
