Background: Attention control in interventional radiology is not yet optimal if compared with diagnostic radiology, but the risk of radiation in interventional radiology is greater than the diagnostic radiology.Objective: To evaluate the level of radiation safety measures by conducting analysis on interventional radiology and vascular cardiac catheterization both therapy and diagnosis in Cath-Lab Room, especially in the Cath-Lab Room 2 of Radiology Unit, RSUP Dr. Sardjito.Materials and methods: Evaluation is done on the structural design of retaining, the leakage rate of X-ray machine, the environmental rate of radiation exposure and dose of radiation workers by comparing between the data with theory.Results: Most of the thick primary and secondary structural barrier has a thickness sufcient although there are still some parts are less. Average of environmental radiation exposure rate is 0,01664 ?R/hr. Then, average of radiation leak rate is 9,225 mR/hr. The average dose received by the doctors and assistants are still far from 20 mSv/year as Dose Value Limit, that is 19,2242 ?Sv/measures for physicians and 9,403 ?Sv/measures for the assistant. The number of measure in the Cath-Lab Room 2 so as not to exceed the NBD 20 mSv/year is a 1.040 measure by doctor and 1.305 act by assistant.Conclusions: In general, the examination room and X-ray machine in Cath Lab Room 2 of Radiology Unit, RSUP Dr. Sardjito Yogyakarta is in a safe condition to operate. Designing of structural barrier, control of environmental radiation exposure rates and the rate of leakage of X-ray machine, and the use of personal protection equipment can reduce radiation dose of Cath-Lab Room 2 sta? in to the lowest possible value so as to ensure the safety of sta? and the community around the Cath-Lab Room 2.
