Radiografer secara umum mempunyai tugas dan tanggung jawab untuk melakukanpemeriksaan pasien secara radiografi meliputi pemeriksaan untuk radiodiagnostiktermasuk kedokteran nuklir dan ultrasonografi (USG) dan melakukan tindakan proteksiradiasi dalam mengoperasikan peralatan radiologi. Penelitian ini bertujuan memprakirakanrisiko pajanan radiasi sinar-X pada pekerja radiasi di Departemen Radiologi RSUPN CiptoMangunkusumo. Dalam perhitungan prakiraan risiko pajanan radiasi sinar-X, dosis pajananradiasi sianr-X radiografer diperoleh dari hasil pengukuran film badge. Data pola aktifitas(lama kerja, frekuensi pajanan dan masa kerja) diperoleh berdasarkan hasil wawancara pada35 radiografer di Departemen Radiologi RSUPN Cipto Mangunkusumo. Berdasarkanperhitungan yang dilakukan, nilai rata-rata Excess Cancer Risk (ECR) lifetime (4,8E-2) danrealtime (1,9E-2). Karena secara teoretis karsinogenisitas tidak mempunyai nilai ambang ataunon threshold, maka prakiraan risiko dinyatakan unacceptable (dosis tidak dapat diterima)bila ECR < E4. Kisaran angka E-4 diperoleh dari nilai default karsinogenistas yang digunakanoleh US-EPA (1990). Berdasarkan perhitungan ECR lifetime dan ECR realtime diperolehgambaran prakiraan risiko efek karsinogenik yang terjadi pada radiografer di DepartemenRadiologi RSUPN CM, dinyatakan aceptable pada risiko kanker baik pada ECR lifetimemaupun realtime.Kata kunci : Analisis risiko, Radiasi, Sinar-X, Radiografer.

Radiographer in general have a duty and responsibility to audit includes examined patientsfor radiodiagnostic including nuclear medicine and ultrasonography (USG), and radiationprotection in radiology and operating equipment. This study aims to estimated the risk ofX-ray radiation exposure to radiographer in the Department of Radiology RSUPN CiptoMangunkusumo using Environmental Health Risk Analysis (ARKL). In calculating theestimated risk forecasts ARKL, risk of X-ray radiation exposure dose radiographer obtainedfrom measurements of the film badge. Data patterns of activity (duration of work,frequency of exposure and years of work) obtained based on the results of a survey of 35radiographers in the Department of Radiology RSUPN Cipto Mangunkusumo. Based on thecalculations performed, the average value of Excess Cancer lifetime Risk (ELCR) is 4,8E-2and the value of Excess Real-time Cancer Risk (ERRC) the average is 1,9E-2. Becausetheoretically carcinogenicity has non-threshold value, then the forecast is declaredunacceptable when ECR < E-4. Range of numbers obtained from the E-4, carcinogenicitydefault values used by the US-EPA (1990). Based on the calculation of the ELCR and ERCRforecasts illustrate the risk of carcinogenic effects that occur in the radiographers in theDepartment of Radiology RSUPN CM, acceptable on cancer risk both in the ELCR andERRC.Keywords: risk analysis, radiation, X-rays, radiographer.
