The concern about occupational exposure is being increased by the worker and regulatory body day by day in Bangladesh. After establishment of Bangladesh Atomic Energy Regulatory Authority (BAERA) this type of study has been carried out extensively for creating database about the safety of occupational worker in different facilities. The present research work has been performed on major non-medical radiological facilities including nondestructive testing (NDT), nucleonic gauge and irradiation facilities. Among these facilities, the workers of Engineer Inspection Services, Bangladesh (EISB) received high radiation doses. The outcome of the present study also shows that the radiation workers of NDT facilities are exposed to more radiation than any other facilities. This is because they used to work with high activity radiation source at offsite area. Every NDT facility should be more equipped with radiation shielding and personal protective equipment. These data can be utilized by BAERA in future for further strengthening of radiation safety infrastructure for the concerned workers.
