“…The μ=ρ constitutes base of various parameters such as Z eff and N eff , energy deposition, and dosimetric behavior. This value can be computed by some programs and is used as reference data (Al-Hamarneh et al, 2017;Eyecioğlu et al, 2017;Gaikwad et al, 2017;Isikli & Berna, 2017;Kurudirek & Onaran, 2015;Kurudirek & Yüksel, 2011;Manohara et al, 2010;More et al, 2016;Singh et al, 2018). Correct μ=ρ values must be obtained to provide basic data in various fields such as radiology, radiation dosimetry, gamma ray fluorescence studies, radiation physics, etc.…”
