“…Various forms of radiation possess varying capacities to ionize substances [1][2][3]. Non-ionizing radiation, including visible light, radio waves, and microwaves, lacks the energy required to displace electrons from an atom [4,5]. Ionizing radiation, a form of electromagnetic radiation, has higher energy levels than non-ionizing radiation.…”

The objective of the research is to develop novel materials that are both inexpensive and have a low density, while also being able to endure the transportation of γ-photons with low-to-medium energy levels. The outcome consisted of four epoxy resins that were strengthened with different quantities of heavy metallic waste. The density of the formed composites improved from 1.134 ± 0.022 g/cm3 to 1.560 ± 0.0312 g/cm3 when the waste content was raised from 0 to 40 weight percent. The theoretical investigation was determined using Monte Carlo (MCNP) simulation software, and the results of linear attenuation coefficient were justified experimentally in a low and medium energy range of 15–662 keV. The mass attenuation coefficient results in a low gamma energy range (15–122 keV) varied in between 3.175 and 0.159 cm2/g (for E-MW0 composite) and in between 8.212 and 0.164 cm2/g (for E-MW40 composite). The decrease in mass attenuation coefficient was detected in a medium gamma photon energy range (122–662 keV) with 0.123–0.082 cm2/g (for E-MW0 composite) and 0.121–0.080 cm2/g (for E-MW40 composite). The density of the enhanced composites influenced these parameters. As the metallic waste composition increased, the fabricated composites’ half-value thickness decreased. At 15 keV, the half-value thickness decreased from 0.19 to 0.05 cm. At 59 keV, it fell from 2.70 to 1.41 cm. At 122 keV, it fell from 3.90 to 2.72 cm. At 662 keV, it fell from 7.45 to 5.56 cm. This decrease occurred as the heavy metal waste concentration increased from 0 to 40 wt.%. The study indicates that as metallic waste concentrations rise, there is a rise in the effective atomic number and a decline in the buildup factors.

“…Recent studies by Chandrika et al (2023) indicate that bismuth-zinc-iron (BiZnFe) nanocomposites (NCs) have been synthesized for the first time using a solution combustion approach and aloe vera extract as a reducing agent, and UV light absorption was observed in the wavelength region of 200 to 300 nm, and the direct energy bandgap was determined as 3.06 eV, thus the ability of BiZnFe NCs to protect against various types of radiation, i.e. X-rays/gamma rays, bremsstrahlung and neutrons, has been evaluated.…”

A documentary review was carried out on the production and publication of research papers related to the study of the variables Aloe Vera and Radiation Absorption. The purpose of the bibliometric analysis proposed in this document was to know the main characteristics of the volume of publications registered in the Scopus database during the period 2012-2022, achieving the identification of 18 publications. The information provided by this platform was organized through graphs and figures categorizing the information by Year of Publication, Country of Origin, Area of Knowledge and Type of Publication. Once these characteristics have been described, the position of different authors towards the proposed theme is referenced through a qualitative analysis. Among the main findings made through this research, it is found that India, with 11 publications, was the country with the highest scientific production registered in the name of authors affiliated with institutions of that nation. The Area of Knowledge that made the greatest contribution to the construction of bibliographic material referring to the study of the variables Aloe Vera and the absorption of radiation, was Pharmacology, Toxicology and Pharmaceutical with 6 published documents, the same presented under the theories of Chemistry. The most used Type of Publication during the period indicated above were Journal Articles with 61% of the total scientific production.
