Beta Backscattering and Gamma Radiation Absorption Characteristics of Carbon Nanoparticles Contained Concrete Composite

Abstract

Concrete is a very important composite for making different building structures to absorb different levels of radiation. Nuclear power plants, nuclear research reactors, particle accelerators and linear accelerator in medical institution use concrete in building construction. Nanoparticles or nanocrystals have different properties than their bulk counterparts. The gamma radiation absorption characteristics and beta back scattering by nanoparticles is also different than their counterparts. In this paper, carbon nanoparticles are mixed in the concrete composite during its preparation. The concrete composite with carbon nanoparticles as admixture were analyzed to provide radiation protection. The gamma radiation absorption characteristics and beta back scattering in ordinary and carbon nanoparticles contained concretes have been studied by GM counter. The results show that using carbon nanoparticles as an admixture in the concrete is one of the solutions for gamma ray shielding and beta back scattering. Therefore, it is good to use carbon nanoparticles as admixtures in concrete composites for beta and gamma radiation scattering and absorption respectively.

Monte Carlo Calculation of linear attenuation coefficients and photon scattering properties of novel concretes loaded with Osmium, Iridium and Barite nanoparticles

“…12 In previous studies, comparisons of microparticles-and NPs-containing concretes have shown higher attenuation coefficients and lower HVLs to protect against energetic photons with Nano-concretes (NCs). [13][14][15] The scattering properties of photons impinging on the walls inside the radiotherapy bunker affect the patients' received whole-body dose from neutrons and photons. In addition, the dose of photons and neutrons reaching the entrance door of the maze is significantly impacted by the scattering properties of the concrete walls.…”
