Design and Performance of INMAS Whole Body Counter
Keywords: Radiation protection, Whole body monitors, K Body potassium
AbstractA whole-body counter has been commissioned at INMAS for radiation protection and clinical applications including body potassium estimations. It has 4-crystal bed geometry inside a shielded enclosure. The background index of the system (counts) per minute per cc detector volume in the energy band 0.1-2 me V is about 0.6 comparing favorably with other whole-body monitors in the world. The sensitivity is 0.5 cpm per gram of K. Body potassium can be estimated can be estimated correct to 10 g for one hour counting. The variation in detector response to a point source on the mid-line of the bed is + - 10% of the mean over a length of 170 cm. The usefulness of the large dimensions of the enclosure chosen is discussed.
