PENGUKURAN DOSIS RADIASI RUANGAN RADIOLOGI II RUMAH SAKIT GIGI DAN MULUT (RSGM) BAITURRAHMAH PADANG MENGGUNAKAN SURVEYMETER UNFORS-XI

ABSTRAKTelah dilakukan pengukuran dosis radiasi di Ruangan Radiologi II Rumah Sakit Gigi dan Mulut (RSGM) Baiturrahmah Padang menggunakan Surveymeter Unfors-Xi. Pengukuran dosis radiasi dilakukan pada 10 titik pengukuran yang di tempatkan di dalam ruangan maupun di sekitar ruangan. Pengukuran dosis radiasi dilakukan saat penyinaran panoramik dan intraoral. Hasil pengukuran dosis radiasi digunakan untuk menentukan efektivitas perisai radiasi. Hasil penelitian menunjukkan interval dosis radiasi pada penyinaran panoramik sebesar 0,37 – 55,69 nGy dan pada penyinaran intraoral sebesar 0,074 – 43,76 nGy. Perisai radiasi Ruangan Radiologi II termasuk perisai yang baik, mampu mengurangi radiasi sebesar 99,33% saat penyinaran panoramik dan 99,83% saat penyinaran intraoral.Kata kunci : dosis radiasi, Surveymeter Unfors-Xi, efektivitas perisai radiasi ABSTRACTResearch on measurement of radiation dose in Radiology Room II in the Dental Hospital of Baiturrahmah Padang using Surveymeter Unfors-Xi has been done. Measurement of radiation dose was conducted at 10 measurement points either in the room or around the room. Measurement of dose radiation was applied at panoramic and intraoral irradiation. The result of dose radiation measurement was used to determine shielding effectiveness of radiation. The result showed that dose interval of panoramic irradiation is 0.37-55.69 nGy and the dose interval of intraoral irradiation is 0.074-43.76 nGy. The radiation shield of Radiology Room II has a good radiation shield, which is able to diminish 99,33% and 99,83% of radiation on panoramic and intraoral irradiation, respectively.Keywords : radiation dose, Surveymeter Unfors-Xi, shielding effectiveness of radiatio
