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 …

Dosimetric Aspects of Poly(ethylene- g - maleic anhydride)
Abstract: Electron spin resonance (ESR) spectroscopy is considered to be finger print technique to identify chemical structures of irradiated polymers. To prove this, ESR spectra of unirradiated and irradiated maleic anhydride grafted poly ethylene (MANPE)are recorded under different conditions. The ESR spectra show multiplehyperfine lines with latent structure corresponding to macro radicals . Radiation dose dependency on chemical structure of MANPE has been investigated by recording ESR spectra at various radiation …

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 …

Mechanisms and Applications of Lyoluminescence
Abstract: When strongly energized halide or organic crystals are dissolved in а liquid solvent like water, light is emitted as an end result of а recombination process. This emission of light is known as Lyoluminesсenсe0. The emitted light intensity, called the Lyoluminescent intensity, depends on а class of factors like radiation doses, probability of radiative recombination, rate of dissolution inside the solvent, etc. The effect is enhanced when the materials have …

Treatment Planning Techniques in External Beam Photon Radiation Therapy
Abstract: Volumetric modulated radiation therapy (VMAT) is a modern treatment technique in radiation therapy, and it delivers conformal radiation dose to the tumor while minimizing dose to the normal tissues. The beam delivery is done in the form of one or multiple arcs, with gantry rotating around the treatment isocenter. A number of literature suggests that VMAT could be an attractive option to treat prostate cancer. However, there is no consensus …
