Occupational Radiation Exposure and Safety Practices in Nuclear Medicine: A Review of Monitoring Studies in Bangladesh
Year: 2025
Type: article
Abstract: Bangladesh has a rich history of nuclear medicine, dating back to the 1960s. Over the years,technological advancements and an increasing number of facilities have led to significant improvements inmedical diagnostics and therapeutic services. However, occupational exposure to ionizing radiation remainscritical for workers handling unsealed radioactive sources in practices like nuclear medicine. Hence,occupational exposure to radionuclides in nuclear medicine requires stringent monitoring to ensure workersafety. This review evaluates the internal and external radiation doses received by nuclear medicine workersin Bangladesh based on seven studies conducted from 2010 to 2024. Data from these studies were analyzedto estimate effective doses and assess compliance with international safety standards. The results show thateffective doses across various facilities were well below the annual average dose limit prescribed by nationalregulation and international organizations like the International Commission on Radiological Protection(ICRP). However, variations in methodology and monitoring practices highlight the need for standardizedprotocols and routine evaluations. This study emphasizes the importance of continued adherence to safetyprinciples and provides evidence for improving occupational radiation monitoring programs in nuclearmedicine practices in Bangladesh. While current safety protocols maintain exposure below prescribed limits,significant variability in individual doses and the increasing complexity of nuclear medicine practicesnecessitate ongoing monitoring and safety protocol enhancements in the country.
