A comprehensive approach for calculation of surface area and volume in radiation transport codes

Hamed Kargaran

Volume 5, Issue 2 , April 2024, Pages 61-69


  The estimation of flux in radiation transport Monte Carlo problems needs to calculate the volumes and surface areas of the geometric regions. The particle flux is often estimated as the track length per unit volume or the number of particles crossing a surface per unit area in Monte Carlo transport problems. ...  Read More

Comparison audit program for selected radiotherapy centers by secondary standard dosimetry laboratory (SSDL) using thermoluminescence dosimeter

Nahid Hajiloo; Mostafa Mohammadi; Omid N. Ghodsi; Hamideh Daneshvar; Soheil Moghtader

Volume 5, Issue 2 , April 2024, Pages 71-75


  The International Atomic Energy Agency (IAEA), sends dosimeters annually to Secondary Standard Dosimetry Laboratories (SSDL) around the world, to calibrate their radiation field. Therefore, they mainly send thermo-luminescent dosimeters as transfer dosimeters to the SSDL laboratories, to be irradiated ...  Read More
