Cesium 137 Irradiator

The Duke Cesium irradiator is a Mark I 68A Cs 137 Irradiator, manufactured by JL Shepherd and Associates in San Fernando, CA. The irradiator cabinet is 37cm x 30cm x 45cm. The bottom of the cabinet houses a chain drive, which gives the user access to three turntable positions. These positions are 4.3cm, 14.3cm and 19.3cm away from the source. There are several different turntable options available: one turntable for 50 mL conicals, and another for 15 mL conicals. The final turntable is a 30 cm aluminum platter, which may be used for either animals or cells.
