This study aims to determine the value of the typical dose rate, the maximum dose rate in the air and the dose rate on the surface of Image Intensifier (II) in 3 types of dual function Fluoroscopy (FL). This study used a dual function Fluoroscopy, X-Ray safe multimeter, Pb plate, Cu plate, and phantom perspek. Typical dose rate measurement were carried out by placing a multimeter X-Ray of phanrom perspek of a thickness of 18 cm, so that the examination table distance from the detector was 18 cm and source distance from image of 96 cm according to normal patient position. Measuring the maximum dose rate in teh air is done by placing the detector at distance of 300 mm above the examination table, placing the Pb 2 mm below the collimator, the exposure is carried out at the maximum automatic kVp. Measuring the dose rate of the surface Image Intensifier (II) is done by placing the detector above II, the Cu plate with a thickness of 2 mmCu is affixed to the surface of the collimator and the exposure is carried out on the automatic kVp. Typical dose rated to test results from FL (A) and FL (C) with the same size II are 35 cm while FL (B) sized II is 23 cm. The results of the tipical dose rate test for FL (A), FL (B), and FL (C) are 11.428 mGy/minute, 11.712 mGy/minute and 12.518 mGy/minute, respectively. All results of the testing of the typical ESD dose rate are still within the test passes which are ⩽17 mGy/minute as required by BAPETAN Regulation No. 2 in 2018. The value of the maximum dose rate in air of each planes is very varied from the maximum value on FL (B) is 11.402 mGy/minutes, while the minimum value occur to FL (C) is 4.311 mGy/minutes. As for FL (A), the maximum dose rate in air is 7.998 mGy/minutes. All results of testing the maximum dose rate in air are still below the test pass value required by BAPETAN which is 50 mGy/minutes. The value of the dose rate of surface II varies greatly from FL (B) having a maximum value is 68.2 µGy/m inutes while FL (A) and FL (C) are 33.3 µGy/minutes and 2.4 µGy/minutes, resvectively. All results of testing the dose rate of the surface of Image Intensifier (II) are still below the test pass value required by BAPETAN which is 60 µGy/minute for size II 23 cm and 90 µGy/minute for size II ⩾ 23 cm.
