Assessing Radiological Security Awareness Following the Cs-137 Radioactive Disposal Failure Incident in Indonesia

In 2020, Indonesia experienced a significant radiological security incident involving the improper disposal of Cs-137, a highly radioactive material, in an empty field near a residential area housing workers of the National Nuclear Energy Agency of Indonesia. The incident led to elevated radiation levels, posing potential health risks to residents and raising concerns about radiological safety practices. This study assesses the level of radiological security awareness among the affected community following the incident. Through a survey, the research evaluates residents’ understanding of radiation risks, safety measures, and their preparedness to respond to radiological emergencies. The study also examines the broader implications of the incident, including its impact on public trust in nuclear safety regulations and the effectiveness of existing awareness programs. Findings highlight significant gaps in knowledge, particularly regarding the nature of radiological hazards and the importance of proper waste disposal. Furthermore, the results reveal the need for enhanced public education, tailored communication strategies, and stronger institutional accountability to ensure radiological security in residential and other vulnerable areas. By addressing these gaps, this research provides recommendations for developing comprehensive awareness campaigns and policies to improve radiological security in Indonesia. It emphasizes the importance of fostering a culture of safety and preparedness, particularly in communities near nuclear facilities, to minimize the risks associated with future radiological incidents. The insights gained can serve as a foundation for strengthening radiological security awareness both locally and globally, contributing to a safer and more informed society.
