The authors obtained theoretical and experimental data on the sensitivity to monochromatic and reaction neutrons of ionization chambers with different sizes of the air cavity between tissue equivalent walls. Significant difference of the sensitivity to neutrons of such heterogeneous chambers was noted as compared to that of homogeneous tissue equivalent ionization chambers. However proceeding from the results of the study we can determine with the precision of 10% the absolute absorbed doses in the dosimetry of biomedical investigations using neutrons of different energies.
作者获得了关于具有不同组织等效壁间空气腔尺寸的电离室对单色中子和反应中子敏感度的理论和实验数据。与均匀组织等效电离室相比，注意到这种异质电离室对中子的敏感度存在显著差异。然而，根据研究结果，我们能够在使用不同能量中子的生物医学研究剂量测定中，以10%的精度确定绝对吸收剂量。
