Homa Berjisi; Ali Pazirandeh

Articles in Press, Accepted Manuscript, Available Online from 22 December 2022

https://doi.org/10.22034/rpe.2022.351237.1095

Abstract
  Digital spectroscopy with Silicon Photomultiplier (SiPM) array coupled on CsI(Tl) crystal, needs some consideration to achieve desirable energy resolution. an array of SiPMs must be used with large scintillation crystal, therewithal signal from whole SiPMs is not ideal. Also silicon pixels are arranged ...  Read More

Maryam Azizi; Ali Biganeh; Omidreza Kakuee; Behjat Ghasemi; Yashar Vosoughi

Articles in Press, Accepted Manuscript, Available Online from 24 January 2023

https://doi.org/10.22034/rpe.2023.374917.1111

Abstract
  Primary standardization of radioactivity is related to the direct measurement of activity in radioactive decay. A large variety of primary standardization techniques have been developed in the past years. The photon-photon coincidence counting is one of the methods for activity determination. This method ...  Read More

Measurement of Radiation and Radioactivity
Experimental and Monte Carlo investigation of neutron detection by THGEM detector in SQS mode

Mohammad Hadi Najarzadeh; Mohammad Reza Rezaie; Ali Negarestani; Ahmad Akhound

Articles in Press, Accepted Manuscript, Available Online from 26 January 2023

https://doi.org/10.22034/rpe.2023.361464.1103

Abstract
  Neutron detection techniques are widely studied in many articles. Most of this research requires a lot of electronic equipment. In this study, using the Thick Gas electron multiplier (THGEM) detector, a new method for neutron detection is proposed to reduce electronic equipment. In the neutron detection ...  Read More

Measurement of Radiation and Radioactivity
Measurement and simulation of the effective annual dose and radiation hazards of Jooshan hot spring in Kerman province

Mahmoud Abdoulahpour; Mohammad Reza Rezaie; Saeed Mohammadi

Articles in Press, Accepted Manuscript, Available Online from 09 February 2023

https://doi.org/10.22034/rpe.2023.374012.1110

Abstract
  Hot springs are known as one of the hydrotherapy centers in the world and have been welcomed due to their healing properties. Due to the presence of radon and radioactive elements in hot spring sediments, water and soil, these components are radioactive. So far, radiation hazards and the annual effective ...  Read More

Measurement of tritium concentration in heavy water by azeotropic distillation

Reza Pourimani; Mohammad Reza Zare; Mehrdad Aghamohammadi

Articles in Press, Accepted Manuscript, Available Online from 01 March 2023

https://doi.org/10.22034/rpe.2023.379666.1113

Abstract
  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
