Dosimeter Co-Card Alarm X-ray Radiation Dosage Monitoring Instrument

Abstract

One type of radiation which is widely used in the field of radiodiagnostic is ionizing radiation. This radiation is a type of radiation with the source of radiation from X-ray devices used in many medical purposes such as Roentgen. Besides giving benefits, radiation has an adverse effect on health when it exceeds specified dose limit. Monitoring radiation doses for most hospitals in Indonesia use passive dosimeters that monitored every month. Dosimeter Co-Card Alarm (DOSCA) is an innovative instrument that combines the application of surveymeter as a gage of dose velocity and dose meter as a gage of radiation dose simultaneously and directly with component advanced electronic in occupational safety and health efforts in the radiation field. At function test in radiology of RSI PDHI Yogyakarta use comparison instrument brand BliT made in China, which is controlled by voltage that starts from 50kV until 90kV, 65mA and 0,08s. The average result of the difference in value obtained between BliT and DOSCA is 0.03μSv. Then the function test in CV. Sehat Sejahtera using voltage 60kV with 5mAs and 10mAs showed the average result of the difference by 0,0μSv. The results of testing instrument showed that DOSCA were able to detect X-ray radiation well.
