摘要
通过实验研究了X和γ射线空气比释动能率、能量对涂硼电离室的线性、X和γ感应度和补偿特性的影响,研究结果表明:涂硼电离室随X和γ射线空气比释动能率变化在一定范围内保持线性,涂硼电离室的X和γ感应度不仅与射线能量有关,还与射线空气比释动能率有关;涂硼补偿电离室的最佳补偿电压需通过工程实践加以确定。
The X and γ ray air kerma rate and energy on boron coated ionization chamber linear,X and γ sensitivity and compensation characteristics are studied by experiment,the results show that boron coated ionization chamber along X and γ ray air kerma rate changes within a certain range to keep linear,X and γ sensitivity of the boron coated ionization chamber is not only related to radiation energy,also with the air kerma rate,optimal offset voltage of boron coated compensation ionization chamber should be determined by engineering practice.
