Modifications induced by gamma irradiation to Makrofol polymer nuclear track detector
The aim of the present study was extended from obtaining information about the interaction of gamma rays with Makrofol DE 7-2 track detector to introduce the basis that can be used in concerning simple sensor for gamma irradiation and bio-engineering applications. Makrofol polymer samples were irradiated with 1.25 MeV (60)Co gamma radiations at doses ranging from 20 to 1000 kG y. The modificati...
متن کاملPolymer Morphological Change Induced by Terahertz Irradiation
As terahertz (THz) frequencies correspond to those of the intermolecular vibrational modes in a polymer, intense THz wave irradiation affects the macromolecular polymorph, which determines the polymer properties and functions. THz photon energy is quite low compared to the covalent bond energy; therefore, conformational changes can be induced "softly," without damaging the chemical structures. ...
متن کاملProton beam dosimetry by CR-39 track-etched detector
Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...
متن کاملPolymer concretes improved by fiber reinforcement and gamma irradiation
The well-known key problem with concrete is that its compressive strength and the compression modulus are insufficient for a variety of applications. Our polymer concrete (PC) consists of an unsaturated polyester resin as the polymeric matrix, silica sand as the inorganic aggregate, plus atactic polypropylene (PP) fibers. A further property improvement can be achieved by gamma irradiation and w...
متن کاملThe protective effect of Sambucus ebulus against lung toxicity induced by gamma irradiation in mice
The aim of present study was to investigate the potential antioxidant and lung protective activities of Sambucus ebulus (SE) against toxicity induced by gamma irradiation. Hydroalcoholic extract of SE (20, 50 and 100 mg/kg) was studied for its lung protective activity. Phenol and flavonoid contents of SE were determined. Male C57 mice were divided into ten groups with five mice per group. Only ...
