Abstract

This study aims to determine the potential risk of thoracic organ cancer in CT Scan examinations using the Size-Specific Effective Dose (SSED) method, considering the importance of accurate radiation dose measurement to minimize the risk of cancer due to radiation exposure. The analysis was conducted on 30 female patients and 30 male patients in the adult category (17 - 45 years) at the Radiology Installation of Prof. Dr. I G. N. G. Ngoerah Hospital, Denpasar, using a descriptive quantitative approach with secondary data. The results showed that the Size-Specific Dose Estimate (SSDE) and SSED values ​​in female patients were 6.51 ± 0.70 mGy and 2.95 ± 0.48 mSv, respectively, while in male patients they were 6.38 ± 0.49 mGy and 2.27 ± 0.26 mSv. The risk of cancer in female patients is estimated at 0.016% and in male patients it is 0.012%. The Anova test showed a significant difference between the dose values ​​of the SSDE and SSED methods, which was caused by SSED only considering the dose of organs covered in the CT Scan image. However, the t-test showed that the doses from both methods did not exceed the BAPETEN standard No. 8 of 2011, so that the thoracic CT Scan examination in this Installation is safe and feasible to use.

Abstract

The results of research that have been carried out, especially in the field of medical physics such as X-rays, have been widely utilized in the medical field, especially Radiology Units in Several General and Regional Hospitals. Thus, it is very important to be understood and known by the community, especially the community, in this case the students of SMA Negeri 2 Kuta. In 2022/2023, there are 507 male and 597 female students. Seeing these conditions, surveys and observations were carried out as a result, students had difficulty understanding physics because the physics subject matter was dense, memorized and mathematical. Seeing these results, it is necessary to carry out a new paradigm in physics learning. One of the more appropriate methods is to balance theory learning with field applications such as natural and artificial radiation measurements and applications in the field of medical physics. The results of natural radiation measurements in the classroom and outside the classroom were 0.605 ± 0.0024 and 0.182 ± 0.0008 mSv/year, respectively. The limit of the dosage rate allowed by BAPETEN is 1,000 mSv/year. Natural radiation identified in the classroom and outside the classroom is still declared safe

Abstract

Kabupaten Karangasem merupakan bagian dari busur kepulauan Sunda Kecil yang terbentuk akibat proses subduksi lempeng Indo-Australia kebawah lempeng Eurasia sehingga menyebabkan daerah tersebut rawan bencana gempabumi. Penelitian ini bertujuan untuk menentukan nilai peak ground acceleration (PGA) di Kabupaten Karangasem menggunakan rumus empiris terpilih. Data yang digunakan adalah data skunder yang diperoleh dari alat accelerograph tahun 2019-2023 dan data dari katalog BMKG tahun 1972-2022. Dalam menentukan nilai PGA digunakan metode empiris Donovan (1973), Esteva (1970), Mc.Guirre (1963), Fukushima Tanaka (1990), Setiawan (2012). Pada hasil penelitian menunjukkan bahwa rumus empiris Donovan cocok untuk diterapkan di Kabupaten Karangasem. Kabupaten Karangasem bagian timur memiliki tingkat bahaya bencana gempabumi paling besar dengan skala Intensitas VI MMI mencakup Kecamatan Karangasem dan Kecamatan Abang dengan nilai PGA tertinggi yaitu 96 gals.
