【摘要】 本文论述了采用平行板电离室监测重离子辐射生物研究中剂量的原理。并就其效率、电离室的饱和特性利用23(?)Pu放射源研究。结果表明从50～1000V的范围内为饱和区;同时对收集效率进行了研究结果表明在饱和区内电压较高时收集好。这说明电离室作为重离子辐射生物实验的剂量监测仪是可行的。更多还原

【Abstract】 The principle dose in heavy ion radiation research using of monitoring the is discussed in the paper. In the experiment. 239Pu (source was used to measure the saturation curve of ionization chamber and calculate the collection efficiency. The experiment show that the saturation area is 50～1000V and the calculated collection efficiency is above 98.6%. The result show that the method of calculation for collection efficiency is reliable and the ionization chamber can be used to monitor the dose in the experiment of heavy ion radiation biological effect.更多还原
