  • Evaluation of natural radioactivity in rocks of Nilgiri hills and their radiation hazard to mankind

    Twenty three rock samples were collected from various altitudes of Nilgiri hills, Tamil Nadu, India. A survey was carried out to determine the activity concentration of selected radionuclides (238U, 232Th, 40K) by means of gamma–ray spectroscopy using NaI (Tl) detector. From the measured spectra, ...

  • Pb–210 irradiation dose estimation for inhabitants living in high natural background areas on Pernambuco/Brazil

    This work was designed to: (a) determine 210Pb concentration in human urine samples of inhabitants of two regions with high natural radiation in the state of Pernambuco - Brazil; (b) estimate radiation dose in bones as a result of this radionuclide incorporation. For this, urine samples of healthy and non–smoker subjects were studied. Pb–210 was separated by ion–exchange resin ...

  • Analysis of the conditions of use of the high-frequency power transformer and design principles

    According to the conditions of use of the high-frequency power transformer (transformer manufacturers) analysis, the overall two-fold: the feasibility and electromagnetic compatibility. Only pay attention to the feasibility of environmental protection awareness, must pay attention to electromagnetic compatibility. Feasibility refers to the specific conditions of use, high-frequency power ...

  • Effect of –irradiation on anti–nutrient, in vitro digestibility and amino acids: profile of sorrel seeds (Hibscus sabdariffa)

    The effect of irradiation (dose levels of 0, 2.5, 5, 10 and 20 kGy) on nutritive (amino acids, and protein digestibility) and anti–nutritional characteristics [total phenols (PH), tannins (TA), phytic acids (PA) and oxalate (OX)], level of anti–nutrients in vitro digestibility (IVPD) and protein digestibilty corrected amino acid score (PDCAAS) of sorrel seeds (Hibiscus sabdariffa), ...

  • More durable or more vulnerable? - Effect of nanoparticles on long–term performance of polymeric nanocomposites during UV exposure

    ZnO nanoparticle is being used as an inorganic UV absorber for polymers. However, the mechanism of how ZnO nanoparticles influence the photo degradation of polymersis is not well understood. This study has investigated the role of ZnO nanoparticles in the long–term performance of a polyurethane (PU) nanocomposite subject to UV radiation. PU samples containing different levels of ZnO nanoparticles ...

  • External and internal radiation doses due to alpha activity in Tafila district, Jordan

    Tafila district of Jordan is unique in the presence of phosphate mines and hot spa which are the major sources of natural radioactivity. Natural radionuclides transfer from soil to vegetables grown in the region, and become a part of people's food. In this study, 16 soil and vegetable samples from Tafila district were collected from eight locations. External absorbed dose rates were calculated to ...

  • Expression of apoptotic genes can distinguish radiation workers from normal population

    Ionising radiation can be produce different forms of DNA damage on living cells. Changes in biomarkers due to exposure to ionising radiation can be an appropriate tool for the immediate recognition of individuals exposed to radiation after a radiological accident or nuclear disaster. QPCR technique, as an approved method, can be used for analysing the expression levels of sensitive genes ...
