CONVENTIONAL ROOM EFFECTIVENESS TEST USING RAYSAFE IN RADIOLOGY UNIT SITI RAHMAH ISLAMIC HOSPITAL PADANG

Abstract

Siti Rahmah Islamic Hospital is a health service center in the city fields with a large number of patients. The more the number of patients, the greater the number the examination was carried out in the radiology room at the Siti Islamic Hospital Rahmah if the walls of the Radiology room are not effective, the dose will be receive to the patient, the patient's family and radiation staff will increase. This research aims to determine the effectiveness and level of security in conventional spaces Radiology Unit of Siti Rahmah Islamic Hospital against radiation with use raysafe unfors. This research was conducted by sticking raysafe unfors from the inside and the outside on walls, doors and Pb glass in a conventional room in the Hospital Radiology Unit Islam Siti Rahmah with the type of quantitative research. The results of the measurement of the largest dose rate were found at the inner 3A point, which was 10.5198 mGy/h. While the results of the measurement of the smallest dose rate are at the outer 7B point, which is -0.0001 mGy/h. The dose before penetrating the material (D0) measured in a conventional room ranged from 10.5198 –1.3228 mGy/h. The dose value that varies at the measurement point is caused by the distance of the radiation source from the measurement point. Where in the conventional room (D0), the largest measured radiation dose is at point 3A 10.5198 mGy/h. This is because the measurement position is closest to the radiation source with a distance of 160 cm. Conventional space buildings are already effective against scattered radiation and safe as a radiation barrier with the effectiveness of values ranging from 99.9% to 100%. The results showed that the ability of walls, doors and Pb in a conventional room in the Radiology Unit of the Siti Rahmah Islamic Hospital absorb radiation.
