Radiation attenuation of boron doped clay for 662, 1173 and 1332 keV gamma rays
Background: Radiation shielding properties is an important for a material wish can be used the photon attenuation coefficients of clay produced using different rate of boron have been measured for the purpose of radioactive waste disposal. Materials and Methods: The measurement has been performed using gamma spectrometer contains NaI (Tl) detector at the photon energies of 662, 1173 an...
متن کاملPreparation of polyvinyl alcohol-polyacrylamide composite polymer membrane by gamma-irradiation for entrapment of urease.
Composite polymer membrane of polyvinyl alcohol (PVA) and acrylamide was prepared on cheesecloth support by gamma-irradiation induced free radical polymerization. The enzyme urease was entrapped in the membrane during polymerization and was cross-linked within the matrix using glutaraldehyde. The membranes could be reused a number of times without significant loss of urease activity.

متن کاملBiodegradable single-polymer composites from polyvinyl alcohol
The microstructure and thermomechanical behaviour of a novel fully biodegradable polyvinyl alcohol (PVOH)-based single-polymer composite (SPC) is presented. Three kinds of PVOH stapled fibres, having different melting temperatures and tensile mechanical properties, were considered as a reinforcement, whilst plasticized PVOH granules were selected as a continuous matrix. Calorimetric tests on th...
متن کاملBentonite Clay as a Natural Remedy: A Brief Review
BACKGROUND From old times, the human kind has used clays, externally or internally, for maintaining body health or treating some diseases. Meanwhile there are few scientific articles reviewing the beneficial effects of clays on body function. Bentonite clay is one of the available clays in nature, used as traditional habits, and remedies in many cultures. METHODS These articles explored among...
