Blessing Okeoghene Ijabor; Akintayo Daniel Omojola; Augustine Onyema Nwabuoku; Funmilayo Ruth Omojola

Volume 4, Issue 2 , March 2023, Pages 1-8

  The study is aimed at measuring the outdoor background ionizing radiation (BIR), the absorbed dose rate (ADR), the annual effective dose (AED) and excessive lifetime cancer risk (ELCR) at four sites in the Aniocha South local government area (LGA) of Delta State, denoted as A-D. The study was performed ...  Read More

Studying the effect of backgrounds on the determination of radiative thermal neutron capture cross-section in the Neutron Powder Diffraction facility of the Tehran Research Reactor

Mahya Pazoki; Hamid Jafari; Zohreh Gholamzadeh

Volume 4, Issue 2 , March 2023, Pages 9-17

  Neutron data and cross-sections are highly regarded and are essential for developing nuclear equipment such as advanced fission and fusion reactors, accelerators, neutron shielding, physics studies, etc. The neutron cross-section should preferably be measured using a single-energy neutron beam, although ...  Read More

Effect of marker material on the dosimetric parameters of I-125 source (model 6711): Monte Carlo simulation

Payvand Taherparvar; Ali AziziGanjgah

Volume 4, Issue 2 , March 2023, Pages 19-24

  Low energy I-125- seeds are considered as a common source in different brachytherapy techniques for treatment of different cancers. In this study, at first, we simulated and validated I-125 (model 6711) seed according to the TG-43U1 recommendation, by GEANT4 Monte Carlo toolkit. Moreover, we simulated ...  Read More

Volume 4, Issue 2 , March 2023, Pages 45-51

  During the operation of Graphite -fuel HTGR (High-Temperature Gas-cooled Reactor) nuclear reactors, Graphite  used as a neutron moderator, is irradiated and has a variety of contaminants (such as Cs-137, Co-60, and Sr-90) and due to industrial and environmental considerations, decontamination of ...  Read More

Assignment of a radiological map of the city of Borujerd in Iran

Reza Pourimani; Mobin Bajelan; Monire Mohebian

Volume 4, Issue 2 , March 2023, Pages 53-60

  The specific activity of radionuclides in the soil of the Borujerd region using high purity Germanium detector (HPGe) was measured and the associated radiological hazards were calculated. The mean specific activity of radionuclides of Ra-226, Th-232, K-40, and Cs-137 in soil was obtained at 10.99±5.11, ...  Read More
