Item A study on estimation of electric quadrupole transition probability in nucleiAKKOYUN, S.; BAYRAM, T. ; KARA, S.O.The reduced electric quadrupole transition probability (B(E2)↑) between 0+ ground state and 2+ state in nuclei is an important quantity because it represents basic nuclear information on energies of low-lying levels in the nuclei. It provides knowledge about deformation of nuclei. In this study, the B(E2)↑ values of some even-even nuclei in 110 ≤ A ≤ 190 region have been estimated by using artificial neural network (ANN) method which is a non-linear approximator. The present study shows that ANN is found to be useful in order to predict B(E2)↑ values of eveneven nuclei in this region.Item Assessment of occupational exposure in non-medical facilities of BangladeshNizam, QMR; Shill, S.; Haider, M.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.
