Production of a novel high strength heavy concrete using tourmaline and galena for neutron and photon radiation shielding
Background: High density concrete is extensively used for efficient radiation attenuation in radiotherapy rooms and nuclear reactors. Over the past eight years, some efficient galena-based concrete samples for shielding X or gamma rays was produced. The goal of this study was to produce a novel high density concrete against neutron and photon radiations using tourmaline and galena. Materials an...

متن کاملFast Neutron Generators: Radiation Levels and Shielding Requirements.
@ Neutron and gamma radiation levels around a Cockcroft-Walton neutron generator producing 14-Mev neutrons at an approximate rate of 1010 neutrons per second were measured under conditions typical of those required for activation analysis. Neutron flux reduction to acceptable levels for limited operation was accomplished by 12 feet of distance that included shielding consisting of 27 inches of ...
متن کاملThe comparison between simple and advanced shielding materials for the shield of portable neutron sources
Background: Monte Carlo simulations play a vital role in the calculation of the necessary shielding both for neutrons and photons. Advanced and simple shielding materials against neutron and gamma rays were compared by simulation using the MCNB4B Monte Carlo code. The simulations were carried out for the three common neutron sources, namely the 252Cf, the 241Am/Be and the DD neutron generator w...
متن کاملthe relation between bilingualism and translation: a case study of turkish bilingual and persian monolingual translation students
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
