Our investigations of an iso-octane-filled liquid-dielectric ionization chamber indicate that this dosimeter is well suited for the measurement of dose distributions at distances close to 252Cf interstitial implant sources. Initial research has shown that such an instrument provides good discrimination between the radiation components of a mixed field and possesses excellent sensitivity. Calculations indicate that iso-octane will yield a neutron and gamma-ray dose response independent of energy over a major part of the 252Cf spectral range, while transmission measurements have demonstrated that the liquid causes little perturbation of the radiation field.
我们对充有异辛烷的液体介质电离室的研究表明，这种剂量计非常适合测量距离252Cf组织间植入源较近时的剂量分布。初步研究表明，这样一种仪器能够很好地区分混合场中的辐射成分，并且具有出色的灵敏度。计算表明，在252Cf能谱范围的大部分区域内，异辛烷产生的中子和伽马射线剂量响应与能量无关，而透射测量表明该液体对辐射场的扰动很小。
