Development of a 2D photon-photon coincidence digital system for absolute activity measurement

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

Volume 4, Issue 3 , June 2023, , Pages 9-14

  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

Design of a two-dimensional pseudo coincidence Compton suppressor system for neutron activation analysis

Ali Biganeh; Banin Shakeri Jooybari

Volume 3, Issue 4 , October 2022, , Pages 17-21

  Compton scattering events are the main source of error on the peak counting during the Neutron Activation Analysis (NAA). The Compton suppressor system in instrumental NAA reduces the detection limit of the technique and leads to a data with a higher degree of precision. In this paper, a two-dimensional ...  Read More
