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.

Cesium-137辐照器设施提供了动物的伽马照射， 培养的细胞。微生物和其他生物材料。剂量测定 辐射化学反应也是适当的应用。 该设施具有Mark I Irradiator，Model 68（J.L Shepherd and Associates， Inc.）它包含两个剖宫产137来源，活动为6,000和100 犬分别。它的特定功能包括： 。一个大的固定腔（宽12英寸，高14英寸），可控制 环境（温度，湿度，大气气体）。 。从0.11 cgy/min的剂量范围很广，没有明显的剂量 减小腔尺寸。 。四个用于电气线的通道，加热或冷却介质， 受控的气流，等。 。可变的狭缝准直仪系统，允许部分照射 没有显着降低腔尺寸的。 。冗余安全互锁以防止人员辐射暴露， 以及不断监视该区域的集成辐射警报。
