  Today, with the development of nuclear technology and radiation therapy equipment, radiation protection is important. This study aimed to design heavy concrete with high compressive strength and effective protection against neutron and gamma rays. In this study, 11 types of concrete with different mixing ...  Read More

Measurement of tritium concentration in heavy water by azeotropic distillation

Reza Pourimani; Mohammad Reza Zare; Mehrdad Aghamohammadi

Volume 4, Issue 3 , June 2023, , Pages 23-27

  In this work, the concentration of tritium in D2O of various degrees of purity was measured. Samples were taken from the Arak heavy water plant and tritium concentrations were determined using a liquid scintillation detector (LSC) based on tritium decay. In this work, instead of simple distillation, ...  Read More

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

Spectrophotometric evaluation of a Nickel-based complex solution for use as a radiation dosimeter

Vahidreza Babaei; Peiman Rezaeian; Sedigheh Kashian; Reza Pourimani; Azam Akhavan

Volume 4, Issue 1 , January 2023, , Pages 19-22

  In this paper, the spectrophotometric properties of a colored Nickel-based solution complex (Nickel nitrate hexahydrate and Methyl Orange (MO)) were investigated as a stable chemical dosimeter for using in radiation processing of agricultural products. Its simple synthesis method as well as low cost ...  Read More

Radiological assessment of different varieties of pistachios produced in Iran

Reza Pourimani; Monire Mohebian; Mobina Abdi

Volume 4, Issue 1 , January 2023, , Pages 61-67

  Nuclear radiations are harmful to the human body. The main sources of nuclear radiation are the decay chains of U-238, U-235, and Th-232 and also some radionuclides as K-40, which are present in small amounts in the materials of the earth's crust, including plants, rocks, soil and water. Radioactive ...  Read More
