Characterization of novel SeTeSn Chalcogenide Glassy Alloy (STS ChGA) as shielding material: Case study of its resistance against γ-ray irradiation for nuclear waste immobilization applications

Radiation shielding competence of SeTeSnIn chalcogenide glassy system: resistance against gamma irradiation

“…Bashter et al [6] and Obaid et al [7] measured the radiation attenuation coefficient of concretes and rocks for gamma radiation. The experimental investigation of gamma radiation at different doses on SeTeSn chalcogenide glass was demonstrated by Srivastava et al [8].…”

“…So, it became very essential to protect the human being from this instant high-dose radiation or radiation of long duration by taking various precautions [1,2]. For this purpose, several shielding materials that can minimize or eliminate the effects of radiation were investigated experimentally as well as theoretically and reported in the literature by different research communities [2][3][4][5][6][7][8][9][10][11][12][13]. Glasses and glass ceramics have an amorphous structure, meaning they lack the ordered crystalline arrangement found in crystalline materials.…”

Attenuation characteristics of high-energy radiation on As-Se-Sn chalcogenide glassy alloy

“…An experimental valuable study were developed by Ankita Srivastava et al about the radiation-induced effects of Gamma rays on Se78Te20Sn2 [20], thermal analysis has confirmed the stability of these materials against recrystallization when exposed to gamma rays and stability against aging effects induced by gamma rays, a slight increase of modulus of elasticity and the microhardness were observed. Also the dielectric features were found to be stable against gamma radiation at high energies except an abnormal increase in dielectric loss at low energies side [20]. For all of these positive features, Ankita Srivastava et al have considered these materials as promising candidate for radiation shielding materials for preventing workers from the harmful effects of nuclear wastes [20].…”

“…From these studies of radiation shielding on chalcogenides, it was found that these materials are better than many of ordinary and commercial glasses and also better than many of the recently developed oxide glasses [17][18][19].

Theoretically various calculations programs have been developed to deduce the shielding factors and hence describe how much the material is suitable to prevent from harmful radiations.…”
