Abstract

Radiation protection is a measure taken to reduce the harmful effects of radiation on health due to radiation exposure. The effectiveness of radiation protection in a room is an important factor in ensuring the safety of patients, healthcare workers, and the surrounding environment from unwanted radiation exposure. Field observations in the CT-Scan room are directly adjacent to other installations such as the NICU, chemodialysis, polyclinics, and patient waiting rooms. This study aims to evaluate the effectiveness of the walls, doors, and leaded glass of the CT-Scan room in blocking radiation according to national radiation safety standards. The study used an experimental quantitative method in the CT-Scan room of the Radiology Installation of RSI Siti Rahmah Padang on August 30, 2025 using a CT-Scan machine, a raysafe unforns X2 multimeter measuring instrument, a building meter measuring instrument and an air phantom. Measurement of the radiation dose rate at 12 different points, representing all components of the room structure, using exposure factors for the cranium, namely 130kv and 240 mAs. Measurements were made on the wall area leading to the surgical polyclinic, NICU room, control panel room, hemodialysis room, lead glass, and the main door, both from the inside and outside of the room. The effectiveness of radiation absorption was recorded in the range of 99.82% to 99.99%, with radiation passed less than 0.2% at all measurement points. The walls covered with 26 cm brick and 2 mm lead, as well as the doors and lead glass, were proven to meet and exceed the minimum effectiveness limit of 90% as stipulated by BAPETEN and the Indonesian Minister of Health Regulation. Thus, it can be concluded that the walls, doors, and lead glass of the CT-Scan room are effective in blocking radiation and have met radiation safety standards.

Abstract

Nasopharyngeal carcinoma is one of the malignant tumors of the head and neck that requires accurate imaging evaluation, with CT scanning being one of the primary modalities. This study aims to determine the effectiveness of CT-scan parameters for evaluating anatomical information in patients with clinically diagnosed nasopharyngeal carcinoma at the Radiology Department of RST Dr. Reksodiwiryo Padang. The research employed observational methods and in-depth interviews with two radiographers and one radiologist, along with a review of patient CT images. Data were collected regarding patient preparation, examination technique, and the conformity of parameters with theoretical standards. The examination was performed with the patient in a supine head-first position, using a scan area from the MAE to the thoracic vertebrae III, slice thickness of 5 mm, window width of 350, and window level of 40. The results showed that although these parameters differ from theoretical recommendations—which suggest a 2.5-mm slice thickness and a more superior scan range—they were still able to visualize essential anatomical structures, including thickening of the nasopharyngeal roof, intracerebral extension, maxillary sinus opacity, parapharyngeal space, oropharynx, paranasal sinuses, orbital cavity, parotid glands, and mastoid air cells. The diagnostic information was considered sufficient to establish the diagnosis of nasopharyngeal carcinoma; however, the radiologist recommended expanding the superior scan range to evaluate the temporal lobe and intracranial involvement when necessary. In conclusion, the CT-scan parameters used at RST Dr. Reksodiwiryo Padang are effective for assessing nasopharyngeal carcinoma, although further optimization remains advisable

Abstract

A panoramic examination is an examination used to show the upper and lower jaws along with abnormalities in the oral area. The lens of the eye is a sensitive organ that is exposed to radiation during a panoramic examination. The lens of the eye that is exposed to radiation for a long time can cause cataracts that can develop to blindness, therefore to prevent cataracts, BAPETEN No. 6 of 2010 sets a deterministic threshold limit for the chance of cataracts at 15 mSv per year. This study aims to determine how much dose the lens of the eye receives during a panoramic examination and whether the dose received exceeds the established NBD. This type of research is an experimental quantitative study conducted at the Radiology Installation of Andalas University Hospital in September 2025 using a sample of 7 patients. The instruments and materials used are a panoramic machine, TLD and plaster isolation. Dose measurement is done by attaching the TLD to the patient's right and left eyelids then exposed using 73 kV, 10 mA and 10.8 s and then the TLD reading process is carried out. The measurement results obtained in nC units with the final result in the form of an effective dose compared with BAPETEN regulation No. 6 of 2010. The highest effective dose measurement result received by patient 2 was 0.13 mSv and the lowest in patient 1 was 0.095 mSv with an average dose received by all patients of 0.11 mSv. Based on BAPETEN regulation No. 6 of 2010, the deterministic threshold for the chance of cataracts is 15 mSv per year, so the range of effective dose values received by the patient is still within safe limits.
