Abstract

Abstract: The current study involves the X-ray/gamma and neutron shielding properties of selected lead based binary/tertiary/quaternary alloys such as Foundary type, Lino type, Molybdochalkos, Mono type, Stereo type, Turne type, Type metal and Woods metal. The X-ray/gamma and neutron shielding parameters are studied in detail for all the selected alloys. Among all the selected alloys, Molybdochalkos shows larger values of mass attenuation coefficient (MAC), absorption buildup factor (ABF), Z eff, N e, specific absorbed fractions of energy (SAFE), radiation protection efficiency (RPE), kinetic energy released in matter (KERMA) and relative dose. Furthermore, neutron total interaction cross section ( σ tot ) and absorption cross section ( σ ab ) values are also larger. This clearly indicates that Molybdochalkos binary alloy is the good absorber of both X-ray/gamma and neutrons. Graphical abstract: Image 1 Highlights: Gamma/X-ray and neutron shielding properties of Lead based binary/tertiary/quaternary alloys are discussed in detail. Developed empirical model produces the change in mechanical property of the compounds due to of X-ray/gamma interaction. Among all the lead based alloys, Molybdochalkos binary alloy shows all the characteristics of the good absorber.
