Calculation of total counting efficiency of a NaI(Tl) detector by hybrid Monte-Carlo method for point and disk sources

Detection efficiency calculation for photons, electrons and positrons in a well detector. Part I: Analytical model

“…[8]). They are generally less realistic, hence less accurate, but are more easily implemented in own software and deliver results faster and free of random sampling uncertainties.…”

The Determination of the Total Efficiency for NaI(Tl) Detector by GATE Simulation

“…Scintillation detectors are the main class of radiation detectors used in many areas (eg in high energy physics, nuclear physics, nuclear medicine, industry, security, geology, astrophysics, agriculture, radiation measurement of environmental samples, etc.) [1][2][3][4]. Hofstadter in 1948 firstly showed that thallium-activated sodium iodide crystals (NaI(Tl)) combining with PMTs (Photomultiplier Tubes) used as an efficient detector to measure gamma-rays and other ionizing radiations [5].…”

Analytical Formulae to Calculate the Total Efficiency of an Arbitrarily Positioned Point Source by an Elliptical Cylindrical Detector

“…By combining Eqs. (14)(15)(16)(17)(18)(19)(20), results in direct mathematical expression for the total efficiency subtended by an elliptical cylindrical detector, from an arbitrarily positioned radiating point source S (p, 0, h).…”

“…Several authors [2][3][4][5][6][7][8] have been treated the issue concerning with the absolute efficiencies determination and have given some useful solutions to this problem. Recently, Selim and Abbas [9][10][11][12][13][14][15] calculated the total and full-energy peak efficiencies for any source-detector configuration using spherical coordinates system.…”
