PEMANFAATAN TIMBAL BEKAS PADA ALAT POTEKSI RADIASI APR SEBAGAI UPAYA PENERAPAN PROTEKSI RADIASI

Abstract

Radiation protection is an action taken to reduce the damaging effects of radiation caused by radiation exposure. Many APRs are damaged or unfit for use where APR is used every day and for a long duration of inspection, due to various factors, including storage methods and incorrect procedures for using APR. The purpose of this research is to utilize Pb which is not suitable for use for repairs as a step to limit and optimize radiation protection for radiation workers and patients and to ensure its suitability from damage. This type of research is qualitative by using the Lead Laminated technique. The study used samples, namely Thyroid Shield with a thickness of 0.5 mm Pb and other supporting tools in the form of AIbon glue as an adhesive as well as handscoons, N95 masks, and aprons as personal protective equipment. Methods of collecting data were observation, documentation, and testing of the thyroid shield. The thyroid shield test was carried out using the MSCT Optima 660 64 slices and DR Y-Sio Max modalities. The data collection process was carried out in 3 stages, namely pre-repair, after post-repair, and after observation within 2 months. Based on the observations in Table 2, it was obtained that the previous cracks were well covered and there were no cracks either in the old location or in the new location. The results of the observations showed promising results in repairing the radiation protection device (APR) on the thyroid shield sample using the lead laminated technique. The image results show that there is no crack after repairing the thyroid shield. However, there are pieces of Pb from the repair that are loose from the thyroid shield, which could be due to uneven gluing and less drying during the repair process.
