FACT SHEET: EPA FACTS ABOUT CESIUM-137

and fat. Cesium-137 remains in the body for a relatively short time. It is eliminated more rapidly by infants and children than by adults. Is there a medical test to determine exposure to cesium-137? Generally, levels of cesium in the body are inferred from measurements of urine samples using direct gamma spectrometry (ICRP Publication 54, 1988).

FAQ RS-2000 Irradiator Rad Source Technologies

The RS 2000 was designed as a direct replacement for Cesium 137 research irradiators. The initial dose rate is set at approximately 1.5 Gy/min (varies minimally per unit). This dose rate will not vary over time, whereas a gamma source begins to decay from the date of creation and thus requires recalculation of time frequently.
