Determination of mass attenuation coefficient of low-Z dosimetric materials

Determination of mass attenuation coefficient for some polymers using Monte Carlo simulation

“…In general, it was found that the µ/ρ values for the polymers (low-Z) were very close to theoretical XCOM data and experimental results. Similar investigation on µ/ρ values has been recently reported for low-Z dosimetric materials using MCNP simulation code [31]. The µ/ρ values calculated by MCNP-4C for polyethylene, nylon 6-6 and PMMA were found to be slightly higher than the experimental results at 59.5 keV photon energy.…”

“…Monte Carlo simulation for mass attenuation coefficients for concretes and heavy metal oxide glasses [6][7][8][9] are reported in literature. Recently an attempt has been made for estimation of the mass attenuation coefficients around the k-edges for low-Z dosimetric materials using the MCNP code which agree very well with theoretical values [10].…”

Variation of Energy Absorption and Exposure Build-up Factor Dependence with Effective Atomic Number and Electron Density of Amino Acids

“…It reflects the behaviour of photon energy increases mass attenuation coefficients decreases. The µ m depending on chemical composition and physical parameter of the composite material discussed by ElKhayatt et al [18]. In energy region 0.01 MeV < E < 0.05 MeV shows the maximum variation with increasing photon energy of mass attenuation coefficients decreasing value of amino acids.…”

Effects of gamma irradiation on some chemicals using an NaI (Tl) detector

“…The study of tissue-equivalent substitutes, dosimetric materials, radiation shielding materials, building materials is useful in radiation protection, medical radiation therapy, nuclear physics, electronics industry, material modification, etc. (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). For the study of these effects, to study the interaction and absorption of gamma rays in materials or samples is also important (14).…”
