  • DNA repair in nuclear workers after occupational exposure to ionising radiation

    Recently, for purposes of radiation safety, the validation of the linear non-threshold (LNT) hypothesis at low doses of radiation was actively discussed. New knowledge, especially on subcellular level, might contribute to the clarification of this problem. The aim of our study was to describe the patterns of spontaneous (rs_sp) and induced (rs_ind) leukocyte DNA repair in workers from the Nuclear ...

  • Exposure to ethylene glycol monobutyl ether and related workers habits in an ink factory

    Ethylene glycol monobutyl ether (EGBE), one of the ethylene glycol ethers (EGEs), is often used as a solvent in surface coatings such as spray lacquers, quick-dry lacquers, enamels, varnishes, varnish removers, latex paint and printing inks; is also used as a cleaning fluid owing to its miscibility with both water and a large number of organic solvents (NIOSH, 1990). Unlike ethylene glycol ...

  • Chromosomal aberrations in Iranian radiation workers due to chronic exposure of X-irradiation

    The frequency of chromosomal aberrations in the peripheral blood lymphocytes of 65 radiology technologists working in hospitals in Tehran, Iran, who had been chronically exposed to X-rays, was analysed. Although film dosimetery did not show the maximal annual permitted dose (20 mSv per year) in any of the examined subjects, cytogenetic analysis detected fairly high levels of chromosomal ...

  • How to deal with asbestos exposure in your workplace: advice for industrial workers

    At one point, more than 75 different industries exposed workers to asbestos. Even though these industries have been made safer by regulations from the National Institute for Occupational Health and Safety, many workers still come in contact with asbestos products that remain at their jobsites. Although most industrial employees face some form of asbestos exposure risks during their career, ...

  • What is the REACH of your exposure?

    Margarethe Jaroszewski of 3E Company looks at the extra burden REACH Exposure Scenarios will bring The REACH Regulation went into effect on 1 June 2007, simplifying but also complicating the compliance work for companies manufacturing or importing chemicals in Europe. As a result, all companies manufacturing, importing, distributing or using chemical substances on their own, in mixtures ...

  • Effects of exposure to portland cement dust on lung function in portland cement factory workers in khash, Iran

    Portland cement is a light grey powder produced by crushing and grinding calcareous materials such as limestone, chalk and argillaceous materials such as; clay and shale, as a wet slurry or in a dry state. The mixture is calcined in a rotary kiln and the resulting clinker is finely ground. The product is composed largely of calcium silicates, calcium aluminates, calcium sulfates, oxides of sodium ...

  • Health monitoring of NPP workers

    The aim of the study is to assess the health status of Kozloduy Nuclear Power Plant personnel in association with their occupational exposure to low doses of ionising radiation (IR) as well as with other factors of their working environment and to determine the probability of the occupational exposure to be a reason for the diagnosed malignant diseases (Probability of Causation – PC). More than ...

  • Protecting Workers From Asbestos

    However, repair, renovation, and demolition operations often generate airborne asbestos, a mineral fiber that can cause chronic lung disease or cancer. The Occupational Safety and Health Administration (OSHA) has developed regulations designed to protect cleanup workers from asbestos hazards. OSHA’s Standards for Asbestos The work of flood cleanup personnel involves the repair, renovation, ...

  • Open questions regarding implications of radioadaptive response in the estimation of the risks of low-level exposures in nuclear workers

    Substantial data indicate that increased levels of chromosome aberrations in lymphocytes can be used to predict cancer risk in humans. One may conclude that a dose of ionising radiation sufficient to produce a certain level of cell damage increases production of antioxidants and repair enzymes that decrease either the frequency of chromosome aberrations or the cancer risk. People in some areas of ...

  • Lead in finger bone, whole blood, plasma and urine in lead-smelter workers: extended exposure range

    Objectives: To assess the historical exposure and to study the relationships between lead concentrations in whole blood (B-Pb), plasma (P-Pb), urine (U-Pb), finger bone (Bone-Pb) and duration of employment in workers at a secondary lead smelter and to compare the relationships between B-Pb and P-Pb with results from previous studies of populations with a wide range of lead exposure. Methods: In ...

  • Workers` silica exposure at Fracking sites far exceeds OSHA Limit, NIOSH study finds

    The concentration of silica in the air workers breathe exceeded occupational health criteria at all 11 hydraulic fracturing sites tested by the National Institute for Occupational Safety and Health, the American Industrial Hygiene Association announced July 31. Researchers measured the silica levels of more than 100 personal breathing zone samples at fracking sites in five states, finding levels ...

  • Suicides and exposure to low doses of ionising radiation

    The suicide rates in southern India are very high (Joseph et al., 2003; Aaron et al., 2004), where there are areas of high natural radiation background (UNSCEAR, 2000). It was a stable tendency towards excess of suicides among the atomic bomb survivors exposed to low doses (0?90 mGy) (Kusumi et al., 1993). It was informed about the direct dependence between the suicide rate and the residency ...

  • 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 ...

  • Risk assessment and brownfields-determining exposure to site contaminants

    The USEPA’s Brownfields Program was developed to facilitate the rehabilitation of contaminated property for re-development. EPA has set forth criteria that must be met for a revitalized property to be used for residential, commercial or industrial purposes. The main thrust of these criteria is the long-term protection of residents or visitors (including shoppers and business employees). As ...
