ABSTRACT
Radiation monitoring is an integral part of good health physics practice at every medical facility performing any radiation therapy activities. It is the core disciplines of RSOs, Health Physicists, Medical Physicists, radiologists, and Nuclear Medicine Techs to be acutely aware of radiation exposure rates for facility staff and patients. Radiation Safety Officers are responsible for all RCA (Radiation Controlled Areas) areas in the buildings. They have the responsibility to keep track of a critical RCA that requires radiation monitoring by using contamination survey meters, area monitoring, or passive and active dosimetry forfacility staff or patients.[3] In this research work, a set of measurements was taken on one of the radiation detectors used in measuring radioactivity, which is the SAPHYMO radiation detector (SAPHYMO, type SPP-2-2NF, scintillation meter, made in France. SN: 992287 – 001923, SN: 992287 – 001925, SN: 00245950, and SN: 03771), to determine the scope of use of the device. The results of the measurements showed the device's high response to radiation after being exposed to gamma rays and X-rays at different distances. It is noted that the measurement rate is very high at short distances. These results confirm the use of the device in environmental measurements and health facilities.
