Description

Once the ionizing radiation is used, routinely survey of radiation dose in the surrounding areas must be performed to ensure radiation safety. This study aimed to measure the radiation doses in the controlled and supervised areas from fluoroscopic room using environmental InLight® optically stimulated luminescent dosimeter (OSLD). The OSLDs were attached at 1.4 m height to the wall, door, and lead glass on the inside and outside of CT and fluoroscopic room to measure the radiation doses of the supervised and controlled area for 10 days. There were twelve and fourteen OSLDs attached position at CT and fluoroscopic room respectively. The results showed that the radiation dose rates of controlled area and supervised area of both x-ray room were 0.4 - 2.1 μSv/week which do not exceed the dose limits. The dose limits for controlled area and supervised area are 0.1 mSv/week and 0.02 mSv/week respectively. While the radiation dose rates in both CT and fluoroscopic room is high, the radiation worker is not recommended to stay in the room for a long time. It can be concluded that it is safe for radiation workers and the public to stay in the controlled area and supervised area. However, the radiation protection rules should be applied if the worker would like to stay in CT and fluoroscopic room during operation.
