Abstract

Industrial radiography poses significant risks of external radiation exposure, particularly in training and operational environments. Effective radiation protection requires comprehensive understanding and application of key safety principles, including time, distance, shielding, and radiation zone identification. This study aims to evaluate external radiation exposure control through a series of practical activities conducted at the Vocational of Nuclear Technology X. Twenty-one participants performed tasks using gamma radiation sources to identify potential hazards, determine control and supervision areas, evaluate dose rate variations with distance and time, and assess the effectiveness of shielding materials. Data were collected through direct measurement and theoretical calculations and analyzed thematically. Findings confirmed that increasing distance and reducing exposure time significantly lowered dose rates, while shielding materials such as lead and concrete effectively attenuated gamma radiation. Conclusions: The study concludes that practical, scenario-based training reinforces technical competencies and safety culture among trainees. The results offer a valuable reference for students, researchers, and radiation workers in understanding external radiation management within radiographic practices.

Abstract

Introduction: Indonesia is highly prone to natural disaster, including volcanic eruptions that often generate sudden public health emergencies requiring rapid coordination and effective management of health resources. The eruption of Mount Semeru in December 2021 caused mass displacement and increased demand for emergency health services in Lumajang District, East Java. Objective: This field report aims to describe the establishment and operationalization of a district-level Health Emergency Operations Center (HEOC) during the acute response to the Mount Semeru eruption. Methods: A descriptive field report design was applied using operational documents, real-time coordination records, and field observations collected during the first ten days of the emergency response. Data were analyzed descriptively to examine coordination mechanisms, information management, volunteer deployment, and logistics monitoring. Results: HEOC activation strengthened command and coordination through routine coordination meetings, centralized health information management, structured volunteer deployment, and integrated logistics monitoring. These mechanisms improved situational awareness, reduced duplication of efforts, and supported timely operational decision-making despite resource constraints. Conclusion: The operationalization of a district-level HEOC enhanced health sector coordination and operational efficiency during the acute response phase. This report provides practical insights into HEOC implementation and highlights its importance for strengthening district-level health emergency preparedness in disaster-prone settings.
