摘要

通过电导率测量，研究了一种新的乳糖辐射剂量测定方法。用60Co对2 - 12wt % %的乳糖溶液进行γ辐照，其中2wt %的灵敏度最佳。与光吸收（1-17.5 kGy）相比，电导率（1-210 kGy）具有更好的线性。在中、高剂量下，电导率的剂量响应灵敏度优于光吸收（0.473 vs 0.147）和（0.252 vs 0.162）。温度显著影响电导率（65°C时增加166.4%）和光吸收率（65°C时增加100.8%）的测量，而日光的影响可以忽略不计。

Electrical conductivity of gamma irradiated lactose for dosimetry purposes

A novel radiation dosimetry method using lactose was investigated through electrical conductivity measurements. 2–12 wt% % lactose solutions were gamma-irradiated using ⁶⁰Co, with 2 wt% showing optimal sensitivity. Electrical conductivity showed superior linearity (1–210 kGy) compared to optical absorption (1–17.5 kGy). At medium and high doses, the dose–response in electrical conductivity had better sensitivity than optical absorption (0.473 vs 0.147) and (0.252 vs 0.162). The temperature significantly affected the measurement of electrical conductivity (166.4% increase at 65 °C) and optical absorption (100.8% increase at 65 °C), while daylight had a negligible effect.
