Abstract

Pemanfaatan pesawat sinar X dapat membawa dampak negatif untuk pekerja dan masyarakat sehingga harus memperhatikan aspek proteksi radiasi seperti penggunaan dinding penahan radiasi yang berfungsi untuk menyerap dan mengatenuasi paparan radiasi yang dihasilkan. Pada penelitian ini dilakukan analisis desain dinding penahan radiasi. Dalam analisis ini dilakukan pengukuran laju paparan radiasi dengan menggunakan Surveymeter Gamma dan perhitungan ketebalan Pb menggunakan metode fitting dan aljabar yang direkomendasikan oleh NCRP No. 147. Pengukuran dan perhitungan Pb di bagi dalam 2 daerah yaitu pada daerah terkontrol (Titik B, Titik C, dan Titik F) dan daerah tidak terkontrol (Titik A, Titik D, Titik E, Titik G, dan Titik H). Hasil pengukuran dan perhitungan dari delapan titik proteksi ini didapatkan laju paparan radiasi pada daerah terkontrol di Titik B (0,052 ), Titik C (0,042 ), dan Titik F (0,055 ( ), dan hasil perhitungan ketebalan Pb di Titik B (0,07 mm), Titik C (0,034 mm), dan Titik F (0,18 mm). Sedangkan laju paparan radiasi pada derah tidak terkontrol di Titik A (0,480 ), Titik D (0,068 ), Titik E (0,075 ), Titik G (0,418 ), dan Titik H (0,453 ), dan hasil perhitungan ketebalan Pb di Titik A (0,46 mm), Titik D (0,08 mm), Titik E (0,071 mm), Titik G (0,038 mm), dan Titik H (0,005 mm). Berdasarkan hasil tersebut, nilai laju paparan radiasi di daerah terkontrol masih dalam batas aman dan di daerah tidak terkontrol laju paparan radiasi yang terjadi berada di atas ambang batas dari nilai pembatas dosis yang ditetapkan oleh NCRP No. 147

Abstract

Continuous exposure to radiation on Cah Lab equipment during procedures can produce significant environmental radiation. Therefore, the safety of medical worked and the public is very important and must comply with PERKA BAPETEN No. 4 of 2020 which sets a radiation exposure limit of 20 mSv/year for radiation workers and 1 mSv/year for the environment or community. This research focused on measuring radiation exposure at three different points in the Cath Lab control room, namely point 1 on the operator's glass, point 2 on the top door, and point 3 on the bottom door. The measurement method uses a Gamma Surveymeter which is placed at a distance of 30 cm from each measurement point, then the radiation background value is recorded and each measurement point is carried out 30 times during exposure during the inspection, with variations in kV and mA. The measurement results show that the radiation exposure value at point 1 (glass) is 0.183 mSv/year, point 2 (the upper door which is parallel to the organ area) is 0.045 mSv/year, and point 3 (the bottom door which is parallel to the organ area reproduction) is 0.102 mSv/yr. All these measurement results are still within the safe limits set in accordance with PERKA BAPETEN No.4 of 2020.

Abstract

The use of X-ray aircraft can hurt workers and the community, so they must pay attention to radiation protection aspects such as the design of radiation retaining walls which function to absorb and attenuate the resulting radiation exposure. This research was conducted to analyze the value of radiation exposure from radiology buildings on peat soil using the NCRP method No. 147. In this analysis, the rate of radiation exposure was measured using a Gamma Surveymeter, and the Pb thickness was calculated using the fitting and algebraic methods recommended by NCRP No. 147. Measurement and calculation of Pb are divided into 2 areas, namely controlled areas (Point B, Point C, and Point F) and uncontrolled areas (Point A, Point D, Point E, Point G, and Point H). The results of measurements and calculations from these eight protection points obtained radiation exposure rates in controlled areas at Point B (0.09 ?Sv/hour), Point C (0.04 ?Sv/hour), and Point F (0.03 (?Sv/hour ), and the results of calculating Pb thickness at Point B (0.07 mm), Point C (0.03 mm), and Point F (0.18 mm). Meanwhile, the rate of radiation exposure in uncontrolled areas at Point A (0.480 ?Sv /hour), Point D (0.068 ?Sv/hour), Point E (0.075 ?Sv/hour), Point G (0.41 ?Sv/hour), and Point H (0.45 ?Sv/hour), and the results of Pb thickness calculations at Point A (0.46 mm), Point D (0.08 mm), Point E (0.071 mm), Point G (0.038 mm), and Point H (0.005 mm). Based on these results, the radiation exposure rate value in controlled areas is still within safe limits, and in uncontrolled areas, the rate of radiation exposure that occurs is above the threshold of the dose-limiting value set by NCRP No. 147.
