ABSTRACT
Ionizing radiation gives immense benefit to the patient in the hospital through diagnostic and therapeutic procedures but unnecessary radiation may cause short- and long-term trouble to healthcare workers & public. The purpose of the study is to monitor the real-time radiation in the Mymensingh Medical College Hospital (MMCH) Campus of Bangladesh and assessment of radiological risks to healthcare workers & public. Real-time radiation monitoring was accomplished in the MMCH campus from August-September 2022 using digital portable radiation monitoring devices through the In-Situ technique. The real-time radiation dose rates & calculated annual effective doses to healthcare workers and the public ranged from 0.25-4.11 µSv/hr (mean: 1.438 ± 0.331 μSv/h) and 0.438-8.585 mSv (mean: 2.529 ± 0.627 mSv) respectively. The excess lifetime cancer risk (ELCR) among healthcare worker & public on the MMCH campus were estimated based on the annual effective dose and ranged from 8.436 × 10-3 to 16.572 × 10-3 (mean: 10.667 × 10-3). The mean ELCR in the MMCH campus is higher than that of the worldwide average value. Real-time radiation monitoring in the big hospital campus is vital for detecting a malfunction of the radiation-generating equipment and wrong handling of the radioactive substance. The study would help for minimizing the radiological risk to healthcare workers & public in the big hospital campus, thereby would ensure the hospital’s environment is free from radioactive contamination.
Keywords: Radiation, Hospital, Healthcare worker, Radiological risk, MMCH, Effective dose, and ELCR.
