用气体探测器监测重离子辐射生物研究的剂量

论述了采用平行板电离富在重离子射生物研究中监测剂量的。结果表明，从５０－１０００Ｖ的范围为饱和区；在饱和区内工作电压较高时收收效率高；这种计算电离室收集效应的方法是可靠的，可以应用在重离子辐射生物效应实验中对剂量进行修正。

Dose measurement with air ionization chamber for heavy ion radiation research

The principle of using an air ionization chamber to monitor doses in heavy ion radiation research is described.A 239Pu α source was used to measure the saturation curve of the ionization chamber and calculated the collection efficiency.The experimental results showed that the saturation voltage ranged from 50 to 1000V,and a higher collection efficiency was obtained at higher voltage in the saturation area.The method of calculating the collection efficiency is reliable and can be used to correct doses in the experiments with regard to biological effects of heavy ion radiaion.
