Abstract

We investigated the ferrous sulphate-benzoic acid-xylenol orange (FBX) aqueous chemical dosimeter for measurement of dosimetric parameters such as the output factor, backscatter factor and lateral beam profiles for different square fields sizes for (60)Co γ-rays. A water phantom was employed to measure these parameters. An ionization chamber (IC) was used for calibration and comparison. A comparison of the resulting measurements with an ionization chamber's measured parameters showed good agreement. We thus believe that the tissue equivalent FBX dosimetry system can measure the dosimetric parameters for (60)Co with reasonable accuracy.

摘要

我们研究了硫酸亚铁-苯甲酸-二甲酚橙（FBX）水性化学剂量计，用于测量钴-60γ射线不同方形射野尺寸下的剂量学参数，如输出因子、散射因子和侧射野剂量分布。使用水模体来测量这些参数。使用电离室（IC）进行校准和比较。将所得测量结果与电离室测量参数进行比较，结果显示出良好的一致性。因此，我们认为组织等效的FBX剂量测定系统能够以合理的精度测量钴-60的剂量学参数。
