Uji Efektifitas Dinding Ruangan Panoramik Instalasi Radiologi RSUD Prof. Dr. MA Hanafiah SM Batusangkar Menggunakan TLD-100

Abstract

Research on the effectiveness of panoramic room walls has been carried out in the Radiology Installation of Prof. Dr. MA Hanafiah SM Batusangkar. This study aims to determine the effectiveness of the panoramic room walls in absorbing radiation emitted by panoramic aircraft, as well as knowing the safety level of the room around the panoramic inspection room in accordance with the dose limit values of workers and the general public. This type of research is a quantitative research by taking direct measurements. The research was conducted by measuring the radiation dose at six points of the panoramic room wall using a radiation measuring instrument, namely TLD-100. The results showed that the effectiveness of the walls was only able to absorb radiation less than 90%, with the shield category on the walls that was not good enough to withstand radiation. Therefore, it is necessary to renovate the panoramic room walls in accordance with safety standards.

Radiation Protection Efforts in Restricting Exposure to Scattered Radiation Based on Room Analysis

“…From the discussion above, it can be concluded that concrete or lightweight concrete (hebel) coated with lead (Pb) can be used as a radiation shielding material. Concrete with a minimum thickness of 20 cm should be given a lead coating of 2 mm, so that it is able to withstand radiation and does not cause negative effects on the health of patients and radiation workers [22][23][24][25][26][27][28][29][30][31][32][33][34][35].…”

Pengukuran Sebaran Paparan Hambur dan Efektifitas Perisai Radiasi di Laboratorium TRO Jakarta II

“…Untuk itu diperlukan suatu pengukuran paparan radiasi hambur di dalam ruangan dan di sekitar ruangan pesawat sinar-X dan perhitungan nilai efektifitas penahan atau perisai radiasi yang ada di sekitar ruangan tersebut. Penelitian yang berhubungan dengan efektifitas penahan radiasi juga pernah dilakukan dengan mengukur paparan radiasi menggunakan TLD 100 untuk radiasi sebelum dan setelah menembus dinding ruang panoramik kurang dari 90% dan kurang efektif dalam menahan radiasi [8]. Penelitian lain memperlihatkan bahwa faktor eksposi juga mempengaruhi paparan radiasi dimana semakin tinggi faktor eksposinya maka semakin besar jumlah paparan radiasinya, jarak titik aman yang direkomendasikan untuk pasien diruang ICU > 3 meter dengan menggunakan kV rendah [9].…”
