In this research, polymers were fabricated through combining polyester, boron oxide (B2O3), and Tellurium (TeO2). B2O3 has good neutron absorption TeO2 is not only highly dense (5.670 g/cm3) but also environment-friendly, compared to PbO, as well being a photon absorber. The radiation protection features for five investigated samples examined utilizing an HPGe detector point sources Am-241, Cs-...

background: in radiation therapy, water is the phantom material of choice, both for reference and for relative dosimetry measurements. solid phantoms, however, are more useful for routine measurements because they tend to be more robust and easier to set up than water phantoms. materials and methods: fluka input data cards have been arranged in sequential order. a simple cylindrical geometry wi...

The primary aim of this investigation is to synthesize a novel glass system with composition (35+x) PbO-5TeO2-20Bi2O3-(20-x) MgO-20B2O3 (where x=0, 5, 10, 15, and 20 mol%) by melt quenching method. confirmation the amorphous behavior presence various vibration modes stretching have been analyzed using XRD FTIR techniques, respectively. radiation shielding parameters these glasses were reported ...

Abstract An innovative cost-effective and lead-free polymer nanocomposite of polyvinyl alcohol/ pyrrolidone was developed. PVA/PVP film contained spherical AgCl SnO 2 nanoparticles facilely prepared via a one-pot synthesis method. The route affords uniform dispersion the both unique features insoluble, dense, nonporous properties. new achieved an efficient gamma radiation attenuation capability...

Abstract Thallium-activated sodium iodide (NaI(Tl)) detectors can be used in gamma cameras, environmental radiation assessments, including emission levels from nuclear reactors, and analysis equipment. This three-phase investigation aimed to model a standard NaI(Tl) detector using the Monte Carlo N-Particle eXtended (MCNPX) general-purpose simulation techniques. Accordingly, was designed along ...

In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-energy technique with only a si...

Introduction: This study introduces a novel polyvinyl chloride (PVC)/tungsten composites with characterization of their shielding properties by employing different techniques. Methods: The PVC/tungsten composites were produced by employing various weight fractions of tungsten micro-particles including 0, 20, and 40 % wt via melt blending method. In the next st...

Considering the negative effects on environment and toxicity of lead, which has been widely used for gamma shielding a long time in nuclear technology, studies have focused development various materials that can be as an alternative to lead radiation shielding. In this research, composite material containing magnetite boron carbide (epoxy/magnetite/boron carbide) transmission technique is empha...
