Study on Occupational Radiation Exposure at Different Hospitals in Nepal using ThermoluminescenceDosimetry

Radiation, which is used extensively to diagnose and treat human disease, possesses an occupational health risk, and if the exposure is higher than the threshold value, it could have deleterious health effects. Given the effects that radiation exposure can lead to, there is a clear need to have a system that affords appropriate levels of radiation protection in a situation where radiation is being used (Aschan 1999). For artificial sources of radiation, the medical sector is dominating the global occupational collective dose (Bhatt and Kulkarni 2013). Monitoring individual radiation workers is an essential and regulatory requirement for the surveillance of radiation workers in diagnostic and interventional radiology, nuclear medicine, and radiation therapy. It allows the individual to get acquainted with whether the possible absorbed dose they are receiving is within the limit as set by ICRP recommendations or not and whether protective ambiance could render safe and practicable services to patients (Gautam and Prashain 2011).
