Numerous studies are reporting the use of polymer composites as gamma-radiation shields. Different barite concentrations 0%, 10%, 20%, 30%, 40%, and 50% were added to epoxy, and the linear attenuation coefficients of the composites increased with the increase in barite concentrations (Al-Sarray et al. 2017 ). The proposed epoxy nanocomposites are established to be useful for the development of improved γ -radiation shielding. Introduction Lately, the applications of γ -rays are ever-increasing in the fields of nuclear physics, medicines, dosimetry, biology, agriculture and industries (Damla et al., 2012a).

Due to the increase in use of radiation energy in many industrial applications, radiation shielding has become a crucial topic in order to diminish its hazardous effects. Radiation shields can be of various weights depending on the materials from which they are produced and the area in which they are used. In this sense, polymer composites have taken attention by researchers because it is. Epoxy resins are a good candidate for radiation shields owing to their low cost, high strength, low toxicity, resistance to corrosion, excellent mechanical properties, and low shrinkage. [ 9, 10, 11] These characteristics make epoxy composites a desirable shield to attenuate neutrons, X-rays, and gamma rays. Malekie, S. & Hajiloo, N. Comparative study of micro and nano size WO3/E44 epoxy composite as gamma radiation shielding using MCNP and experiment. Chin. Phys. Lett. 34(10), 108102 (2017). A comprehensive investigation on the effect of gamma radiation on epoxy-lead oxide composites has been carried out highlighting upon the chemical structure, thermal stability, mechanical stability, surface morphology and gamma attenuation properties.

The epoxy resin utilised in this work was E−110I/H-9 type, which falls under the category of thermosetting polymers. The molecular formula of epoxy resin is C 21 H 25 ClO 5 and its density is 1.1 g/cm 3. It consists of two parts, namely, a resin with epoxide rings at the ends of its molecules type (E−110I) and a curing agent or hardener. The proposed epoxy nanocomposites are established to be useful for the development of improved γ -radiation shielding. Keywords Attenuation coefficient Effective atomic cross-section Effective atomic number Effective electron number WINX COM program 1. We developed new composites for photons shielding applications. The composite were prepared with epoxy resin, red clay and bismuth oxide nanoparticles (Bi2O3 NPs). In order to establish which. The gamma irradiation treatment of epoxy resins composites offers many advantages compared with conventional thermal curing, such as a reduced time, ambient temperature, greater flexibility [5], changes in physical, optical, electrical properties, or morphological structure [2,9,10]. Often, epoxy resins are amorphous in nature and it is.

Herein, carbon-doped boron nitride (BCN), modified by two silane coupling agents, was used to fabricate epoxy composites, and the effect of gamma irradiation on the properties of epoxy resin composites was investigated. The research showed that the modified BCN/epoxy composites prepared herein exhibited excellent mechanical and thermal. By Richard Thompson. Scientists in China have designed and developed a series of epoxy thermoset resins containing gamma ray-responsive bonds. The new polymers, which have mechanical.
The epoxies are usually heavy and viscous materials with a molecular weight of approximately 370, with a wpe (weight per epoxide group) of about 180 and a viscosity of 1100 to 1500 mPa-s at 25°C. - 2 - Several factors affect the behaviour of epoxies subjected to ionizing radiations, including the radiation environment and the presence of additives.

We have attempted to develop the gamma radiation shielding abilities of newly prepared epoxy composites by introducing ZrO2. The radiation shielding parameters are experimentally reported below. The experimental setup included an HPGe detector and different radioactive point sources which emitted photons with energies of 0.06, 0.662, 1.173, and 1.333 MeV. The gamma radiation shielding. The aim of the current study is to investigate the impact of introducing micro- and nanoparticle MgO as a filler into epoxy resin on the radiation shielding abilities of the prepared samples. To this end, we performed a gamma-radiation spectroscopy experiment with the help of an HPGe detector and Am-241, Cs-137, and Co-60 sources. We evaluated the particle size effect (PSE) and detected the.
