Spectral deconvolution approach for Beryllium-7 detection: Evaluating soil redistribution with NaI(Tl) detectors Radiat. Phys. Chem. (IF 2.8) Pub Date : 2024-08-28 João M.F. Lopes, Fábio L. Melquiades, Rodrigo O. Bastos, José F. de Oliveira, Graziela M.C. Barbosa, Avacir C. Andrello
Beryllium-7 is a cosmogenic radionuclide produced in the upper atmosphere through the spallation of cosmic rays and falls to Earth mainly by wet deposition. Given its short half-life (53 days) and strong adsorption to the clay present in the soil, Be inventory can be evaluated to obtain information about soil redistribution over periods of up to 6 months. By performing these measurements, one can infer

Exploring the potential of attapulgite clay composites containing intercalated nano-cadmium oxide and nano-nickel oxide for efficient radiation shielding applications Radiat. Phys. Chem. (IF 2.8) Pub Date : 2024-08-25 Hani H. Negm, Elhassan A. Allam, Islam M. Nabil, Eslam Abdeltwab, Massaud Mostafa, Atef El-Taher
An innovative nanocomposite material, denoted as ATCdNi, has been developed by incorporating attapulgite (APL) clay with two different nanometal oxides, CdO and NiO, at varying proportions to serve as promising alternatives for shielding against γ-rays. The composition of the material is represented as 40%APL + X%(CdO)+(60–X)%(NiO), with X values of 15%, 30%, and 45%. Several characterization techniques

Quantitative and qualitative performance evaluation of commercial metal artifact reduction methods: Dosimetric effects on the treatment planning Radiat. Phys. Chem. (IF 2.8) Pub Date : 2024-08-24 Mohammad Ghorbanzadeh, Seyed Abolfazl Hosseini, Bijan Vosoughi Vahdat, Hamed Mirzaiy, Azadeh Akhavanallaf, Hossein Arabi
The presence of metal implants within CT imaging causes severe attenuation of the X-ray beam. Due to the incomplete information recorded by CT detectors, artifacts in the form of streaks and dark bands would appear in the resulting CT images. The metal-induced artifacts would firstly affect the quantitative accuracy of CT imaging, and consequently, the radiation treatment planning and dose estimation
