用小监测仪和热释光元件对上海5台加速器机房周围进行了瞬时和月累积剂量测定。大部分防护剂量均在安全范围内,主屏蔽外瞬时漏泄量一般为副屏蔽外瞬时漏泄量的8倍,主屏蔽外月累积剂量是副屏蔽 A small monitor and a thermoluminescence element were used to measure the instantaneous and monthly cumulative dose of 5 accelerator rooms around Shanghai. Most of the protective doses are in the safe range, the main shield outside the instantaneous leakage is usually outside the deputy shield instantaneous leakage of 8 times the main shield outside the cumulative dose is a secondary shield
