Electron beam irradiation studies of polyethylene maleic anhydride on their Chemical and Thermal properties.
Abstract: The electron beam (e-beam) irradiation effects on polyethylene maleic anhydride (MANPE) are investigated by spectroscopic and thermal methods. The MANPE irradiated with electron beam to a radiation dose of 30, 60 and 90 K Gy and the resultant changes in their chemical structure and thermal properties have been investigated by Electron spin resonance (ESR), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), X-ray diffraction (XRD) and scanning electron microscopy …

Effect of Gamma and Electron Beam Irradiations on Crystalline and Gelatinization Properties of Edible Potato Starch
Abstract: Exposure of food material to radiation causes changes in crystalline (damage of crystal structure / lattice distortion), and gelatinization (digestive)properties. Potato starch (PS) is one of the important globally used food supplement in different forms like chips, curries, cusins etc. During its use the PS is exposed to radiations, altering its molecular structure (due to chain cleavages) and bring changes in structural and physical properties ; sometimes ill – effects …

Structural and Electrical Properties of Low-Energy Ion Beam Kr-Irradiated In/Se Bilayer
Abstract: In the present work, In (~50 nm) over Se (~50 nm) thin films were deposited successively on an Si substrate by e-beam evaporation method under 2×10–5 mbar pressure. The In/Se bilayers were irradiated with low-energy ion beams of 350 keV Kr+1 with fluence of 3 × 1016 ions/cm2. The sample was subsequently characterized for phase formation using X-ray diffraction and thickness profile using Rutherford backscattering spectrometry analysis. In the pristine …

Effect of Radiation Dose, Dose Rate and Annealing Temperature on Edible Potato Starch by Spectroscopic Methods
Abstract: Potato starch (PS) is a favorite food choice in different forms. During its storage and applications the PS is exposed to different radiations. In the present study the authors attempt to compare radiation effects (gamma and Electron beam of same radiation dose) in PS by Electron spin resonance (ESR) and Fourier transform infrared (FTIR) methods. ESR spectra of gamma irradiated PS appeared to have resolved shapes than the electron beam …

Revealing the Effect of Swift Carbon Ion Beam on Radiation Sensitivity of Radio-frequency Magnetron Sputtered Grown Alumina Thin Films
Abstract: Regarding targeted treatment, hadron therapy is beneficial than conventional radiotherapy based on X rays/gamma rays due to characteristic energy loss profile of energetic charged particle during ion matter interaction. In this regard, dose monitoring and its precise measurement with spatial accuracy are very crucial. Thermoluminescence (TL) based thin film radiation dosimeter has the potential to serve this purpose. In hadron therapy, use of swift carbon ion beam is found to …

Dose Rate Mapping Resulting from Water Unloading in the Tangential Tube
Abstract: Abstract The objective of this study aims to calculate the expected dose rate distribution in the neutron experimental area of research reactor due to unloading water from the tangential tube. The tangential tube is one of the irradiation neutron beams in open pool reactor which installed to conduit a neutron physics experiment. Unloading water from the tangential tube is a process aims to reaching neutrons emitted from the reactor core …
