The Cesium-137 Irradiator Facility provides gamma irradiation of animals, cultured cells. microorganisms and other biological materials. Dosimetry and radiation chemistry reactions are also appropriate applications. The Facility has Mark I irradiator, Model 68 (J.L Shepherd and Associates, Inc.) It contains two Cesium-137 sources with activities of 6,000 and 100 curies, respectively. Its specific features include: . A large, fixed cavity (12" wide and 14" high) with a controllable environment (temperature, humidity, atmospheric gases). . A wide range of dose rates from 0.11 cGy/min without a significant reduction in cavity size. . Four access tubes for electrical leads, heating or cooling media, controlled airflow, etc. . A variable slit collimator system which allows partial irradiations without a significant reduction in cavity size. . Redundant safety interlocks to prevent radiation exposure of personnel, and an integrated radiation alarm that monitors the area constantly.

铯-137辐照设施为动物提供伽马辐照， 培养细胞微生物和其他生物材料。剂量测定 和辐射化学反应也是合适的应用。 该机构有Mark I辐照器，型号68（J.L Shepherd and Associates， 公司）它含有两个铯-137源，放射性活度分别为6，000和100 居里，分别。其具体特点包括： .一个大的固定腔（12”宽，14”高）， 环境（温度、湿度、大气气体）。 .从0.11 cGy/min的宽剂量率范围内， 减小空腔尺寸。 .四个用于电线、加热或冷却介质的接入管， 控制气流等。 .允许部分照射的可变狭缝准直器系统 而不显著减小空腔尺寸。 .冗余安全联锁装置，防止人员受到辐射， 以及一个持续监控该区域的综合辐射警报器。
