  • Radiation prevents much cancer

    Evidence reviewed here supports the concept that chronic exposure to ionising radiation can dramatically decrease cancer incidence and mortality. This evidence includes an inverse relationship between radiation levels and cancer induction and/or mortality in: over 200 million people in the USA; 200 million people in India; 10,000 residents of Taipei who live in cobalt-60 contaminated homes; high ...

  • Individualisation of personal space in hospital environment

    The purpose of the paper is to test a Low Exergy heating and cooling system (LowEx system) that enables the creation of healing and comfort conditions for individual user with minimal possible energy use. The LowEx system was tested in a model room for burn patient and compared with the conventional one. Thermal comfort conditions were simulated for three individual users (burn patient, ...

  • Physical dosimetry system in radiation accidents

    We experience various types of radiation accidents. When a radiation accident happens, one of the important aspects that we have to consider is the radiation dose to the victims of the accident. To judge the health effects due to radiation exposure, it is necessary to make a dose assessment. There is a variety of dose assessment methods, of two types: biological dosimetry and physical dosimetry. ...

  • Molecular evidence of radiation hormesis at occupational exposure

    The idea of favourable effects of low dose ionising radiation in biological systems has existed for many years and is the basis of radiation hormesis hypothesis. New evidence at subcellular levels might contribute to further clarify this problem. We used molecular epidemiological biomarkers (DNA/protein changes in peripheral blood; immunological changes in lymphocytes) in occupationally-exposed ...

  • The design of an ICT module for radiation protection training purposes

    The Nuclear Research Center of Algiers (CRNA) organises each year radiation protection training courses to the benefit of such users from both the industrial and the medical fields. The Algerian Atomic Energy Commission (COMENA) has taken active steps towards the incorporation and adoption of ICT-based training modules in nuclear science and technology and related applications. The objective of ...

  • Evaluation of occupational radiation exposure of cardiologists in interventional radiography in Mashhad CATHLABs

    Several studies have revealed that interventional radiography procedures performed in cardiology departments are high dose techniques. In this study, effective dose of cardiologists working in hospitals Catheterisation Laboratories (CATHLABs) in Mashhad city have been measured during Coronary Angiography (CA) and Percutaneous Transluminal Coronary Angioplasty (PTCA) procedures. In order to ...

  • Low dose response of human lymphocytes in vitro and its dependence on the antioxidant status of donor persons

    The individual responses of persons were studied in vitro by lymphocyte micronucleus assay following X-irradiations of 0.7 and 0.25 Gy. Linear correlations of a different coefficient, R, were found with the normal total antioxidant level (TAS value) of the donors' sera: the higher the antioxidant status the less the radiation-induced micronucleus increment. The cytogenetic effect of low doses ...

  • The significance of DNA repair genes polymorphisms on development of non–cancer pathology in Chornobyl nuclear power plant accident sufferers and convalescents of acute radiation syndrome

    The aim of the study was to find an association between XRCC1 (Arg399Gln), XRCC3 (Thr241Met) and XPD (Lys751Gln) gene polymorphisms and non–cancer diseases in 87 sufferers of the Chornobyl nuclear power plant accident using polymerase chain reaction–restriction fragment–length polymorphism analysis. As controls, 109 healthy donors were studied. The distribution of studied polymorphisms was not ...

  • Calibration and characterisation of extremity dosimeters

    The increasing use of radiation in the medical field is providing great advances in health improvement. However, these techniques can generate an increase in the number of professionals exposed to radiation. The Brazilian authorities (Brazilian Nuclear Energy Commission ? CNEN) have imposed the monitoring of specific body parts of professionals. One of these obligations is the monitoring of the ...

  • Low-dose monitoring for occupational exposure and the influence of measurement accuracy

    This paper presents the evolution of individual radiation doses received by occupationally exposed workers. The individual doses accumulated over the period 2000-2007 correlated to nuclear laboratory and radiation source (gamma, X-rays) types are in the low radiation range. Dose equivalent Hp(10) was measured by a film dosimeter system; the influence of the measurement accuracy on the results was ...

  • Nuclear law stands on thin ice

    Revealing the questionable actions of many radiobiologists exposes the Achilles heel of nuclear law. Documentation of systematic deception is reason enough to change nuclear law. Much evidence comes from mis-statements by seven committees for the Biologic Effects of Ionizing Radiation (BEIR). These fraudulent interpretations led ignorant physicians, the media and government officials to accept ...

  • The evaluation of the dose equivalent to the people accompanying patients in diagnostic radiology using the MCNP4C Monte Carlo code and TL dosimetry

    The general purpose Monte Carlo N-Particle Radiation Transport Computer Code (MCNP4C) was used to calculate the equivalent dose to the person or people accompanying patients who have been exposed to radiation that was scattered from the patient. To do the calculations, two homogeneous water phantoms were used to simulate the patient and the accompanying person. Finally, in the case of source ...
