Gamma, Beta and Neutron Dose Rate Level Investigation at Different Key Points of BAEC TRIGA Research Reactor

The 3MW BAEC TRIGA MARK-II Research Reactor (BTRR) has been on operation for more than 33 years under the supervision of scientists/ Engineers of Center for Research Reactor, AERE. The reactor is operated at different power levels according to the demand of user group who performs different experiments and sample irradiation as well as research work for academic purposes. Around any nuclear facility, safety of the reactor personnel and radiation workers is the highest priority. Therefore, it is very much important to have the knowledge and data about the radiation dose rate level at different points around the facility at different power levels. From this study certain factors were revealed. Higher dose rates were found at radial beam port-I and piercing beam port caused by neutron leakage. Also, neutron dose rates were found a bit higher than the background level near main entry door. The authority has been informed to take appropriate actions. Overall, this study sets some standards for future activities related to radiation dose measurements in future. This paper is less for experiments but is primed for the radiological safety of the individuals related to reactor facility.
