Estimation of indoor radiological hazard on worker and public health in atomic energy centre Dhaka campus, Bangladesh

Abstract

Introduction: Radiation gives tremendous benefit to mankind but unnecessary radiation may pose harm to worker and public. The purpose of the study
is to continuous indoor radiation monitoring of Atomic Energy Centre Dhaka (AECD) campus to minimize the radiological risk on worker and public
health in and around the campus.

Materials and methods: Continuous indoor radiation monitoring was conducted in the AECD campus from November 2018-April 2019 using the
Thermoluminescent dosimeters. The excess life-time cancer risk on worker
and public health were estimated based on the continuous indoor radiation
monitoring data.

Results: The annual effective doses to the worker and public from indoor radiation were ranged from 0.28±0.11 mSv to 0.67±0.25 mSv and the mean was
found to be 0.43±0.10 mSv. The excess life-time cancer risk (ELCR) on the
radiation worker & public health were estimated based on the annual effective dose and ranged from 1.13 Χ 10-3 to 2.65 Χ 10-3 with an average of 1.72
Χ 10-3.The average annual effective dose and ELCR on worker and public
health were lower than those of the worldwide average values.

Conclusion: The radiological hazard on worker and public health in and
around the AECD campus is not significant because those values are lower
than the recommended values of the international commission on radiological
protection. Monitoring of these indoor places would help in keeping a record
of safe working practices during the handling of the radioactive substances
and radiation generating equipments in a radiological facility.
