Abstract

Thermoluminescence response of TLD CaSO4: Dy with a variation of the addition of SiO2 and PTFE materials has been observed. TLD CaSO4:Dy derived through co-precipitation method and then added by SiO2 and PTFE. Thermoluminescence intensity for CaSO4:Dy added by SiO2 obtained 9.41, 5.32; and 13.93 nC for the temperature at 400 °C, 600 °C and 700 °C. As for CaSO4:Dy with the addition of PTFE obtained 33.10;  336.89; and 1191.11 nC for the temperature at 400 oC temperature, 600 °C and 700 °C. Thermoluminscence intensity for CaSO4:Dy without the addition of SiO2 and PTFE at a temperature of 700 °C is 75.15 nC. There’s a significant increasing in the thermoluminescence intensity on CaSO4:Dy added by PTFE.

Abstract

Aplikasi radiasi di bidang medik merupakan penyumbang terbesar dari paparan radiasi yang diterima oleh populasi dunia. Tujuan: Mengetahui tingkat dosis radiasi yang diterima pekerja dan pasien pada saat dilakukan tindakan intervensi yang dilakukan di Rumah Sakit Umum Pusat (RSUP) Dr. M. Djamil, Padang. Metode: Penelitian dilakukan pada bulan Februari sampai Maret 2018 dengan mengukur dosis pekerja menggunakan dosimeter termoluminesensi (TLD) dalam bentuk chip, dan merekam kerma dan KAP (kerma-area product) pasien yang ditampilkan pada layar monitor pesawat sinar-X. Hasil: Perawat yang terlibat dalam tindakan PAC menerima dosis efektif, dosis tiroid dan dosis ovarium tertinggi sebesar masing-masing 0,1043 mSv, 0,1141 mSv dan 0,1040 mSv, sementara dosis lensa mata tertinggi sebesar 0,3020 mSV diterima perawat dalam tindakan pemasangan pacu jantung, dan dosis ekstremitas jari tertinggi sebesar 0,3964 mSv diterima dokter yang melakukan tindakan angio dan PTCA elektif. Untuk pasien, kerma tertinggi sebesar 3053 mGy dan KAP tertinggi sebesar 16443 cGy cm2 diterima oleh pasien yang menjalani tindakan PAC diikuti PTCA. Simpulan: Dosis radiasi tertinggi yang diterima pekerja radiasi menyiratkan bahwa tidak hanya dokter namun perawat juga dapat menerima dosis radiasi tertinggi, sedangkan pasien diduga menerima risiko efek deterministik dan efek stokastik terbesar saat menjalani tindakan PAC diikuti PTCA.Kata kunci: dosis pasien, dosis pekerja, tindakan intervensi, paparan medik

Abstract

Research has been carried out regarding the evaluation of the application of radiation protection to rooms and radiation workers in the Radiology Installation at Andalas University Hospital. The aim of the research is to evaluate the radiation dose rate on the inside and outside walls of the room, evaluate the radiation dose rate received by radiation workers, and evaluate the completeness of the work area and radiation protection for radiation workers. Evaluation of the radiation dose rate on the radiation shield wall was carried out using the TLD-100 in the CT-Scan, conventional X-ray and dental rooms. Evaluation of the radiation dose rate received by radiation workers is carried out using the TLD badge worn by radiation workers. Evaluation of the completeness of the work area is carried out by directly observing the radiology room, then conducting interviews with radiation workers. The research results showed that the highest radiation dose rate was obtained in the CT-Scan room and the lowest was outside the dental room at the entrance, without exceeding the Dose Limit Value (NBD) set by BAPETEN Regulation No. 4 of 2013 of 20 mSv/year for radiation workers and 1 mSv/year for the general public. The radiation dose rate value received by radiation workers is still below the NBD set by BAPETEN Regulation No. 4 of 2013 amounting to 20 mSv/year. The results of the evaluation of the completeness of the work area and radiation protection in general have met the provisions of BAPETEN Regulation No. 4 of 2020 except for danger signs in conventional X-ray and CT-Scan rooms.
