Proteksi Radiasi Laboratorium Kampus Radiologi dalam Menunjang Praktik

Abstract

• Abstrak. Laboratorium pendidikan radiologi merupakan sarana pembelajaran yang memanfaatkan radiasi pengion sehingga penerapan proteksi radiasi menjadi aspek penting dalam menjamin keselamatan mahasiswa selama kegiatan praktik. Penelitian ini bertujuan untuk mengetahui proteksi radiasi di laboratorium pendidikan radiologi dalam menunjang keselamatan radiasi mahasiswa serta penerapan proteksi radiasi oleh mahasiswa selama praktik. Penelitian menggunakan metode deskriptif dengan pendekatan mixed method. Data kualitatif diperoleh melalui wawancara dengan Ketua Program Studi Radiologi, sedangkan data kuantitatif diperoleh melalui survei terhadap 54 mahasiswa menggunakan kuesioner skala Likert. Hasil penelitian menunjukkan bahwa laboratorium telah menerapkan proteksi radiasi melalui penyediaan alat pelindung radiasi, desain ruangan yang memenuhi aspek keselamatan, penggunaan parameter eksposi yang optimal, serta pemantauan dosis menggunakan Thermoluminescent Dosimeter (TLD). Tidak ditemukan mahasiswa yang menerima dosis radiasi melebihi Nilai Batas Dosis (NBD) berdasarkan hasil pemantauan. Hasil survei menunjukkan bahwa 77,2% mahasiswa sering menggunakan TLD, 59,6% sering menggunakan apron, dan 100% sering menerapkan prinsip keselamatan radiasi berupa pengaturan jarak, waktu, dan shielding. Disimpulkan bahwa sistem proteksi radiasi di laboratorium telah menunjang keselamatan mahasiswa, meskipun kepatuhan penggunaan TLD dan apron masih perlu ditingkatkan.
• Abstract. Radiology education laboratories are learning facilities that utilize ionizing radiation; therefore, the implementation of radiation protection is a critical aspect in ensuring student safety during practical training. This study aims to examine radiation protection measures in radiology education laboratories to support student radiation safety, as well as the implementation of radiation protection by students during practical training. The study employed a descriptive method using a mixed-methods approach. Qualitative data were obtained through an interview with the Chair of the Radiology Study Program, while quantitative data were obtained through a survey of 54 students using a Likert-scale questionnaire. The results showed that the laboratory had implemented radiation protection through the provision of radiation protective equipment, a room design that met safety requirements, the use of optimal exposure parameters, and dose monitoring using Thermoluminescent Dosimeters (TLDs). Based on the monitoring results, no students were found to have received radiation doses exceeding the Dose Limit Value (DLV). Survey results showed that 77.2% of students frequently used TLDs, 59.6% frequently used aprons, and 100% frequently applied radiation safety principles such as distance, time, and shielding. It was concluded that the radiation protection system in the laboratory has supported student safety, although compliance with the use of TLDs and aprons still needs to be improved.
