  • Mitigation of workplace radon gas concentration using high–performance epoxy resin coating

    The indoor radon gas released from concrete was measured using a 0.65 × 0.65 × 0.65 m fabricated concrete slab room, simulating a workplace. The indoor radon gas concentration was monitored, and the remediation method was examined. Radon concentrations were monitored using Radon Monitor Model 1023 from Sun Nuclear. Results show that average radon concentrations reached 111 ...

  • How healthy is your child’s school

    I was called recently by a concerned parent. His school was undergoing mold remediation during school hours. Also, the Shigella bacterium has closed several schools in the Birmingham area. Just how safe are your children in their school, and how can you help to ensure that they are in a safe environment? By being proactive and asking questions. The biggest problems regarding ...

  • January is National Radon Action Month

    January is National Radon Action Month and the EPA and the U.S. Surgeon General are urging all Americans to take action and protect their health by testing their homes, businesses, schools and other buildings for radon. Radon is impossible to detect by humans as you can’t see, smell or taste it but it is the leading cause of lung cancer deaths among nonsmokers in America claiming the lives ...

  • Prevention measures against radiation exposure to radon in well waters: analysis of the present situation in Finland

    Naturally occurring radioactive elements are found in all groundwaters, especially in bedrock waters. Exposure to these radioactive elements increases the risk of cancer. The most significant of these elements is radon which, as a gas, is mobile and dissolves in groundwater. In Finland, water supply plants are obliged to carry out statutory monitoring of the water quality, including radon. ...

  • Exposure to radon in tourist caves in Cuba

    With the objective of estimating the dose due to radon-222 received by tour guides and other people who work inside some of the most important tourist caves in the Republic of Cuba, measurements of radon concentrations were carried out in four of these caves. All the studied caves are located in Vinales Valley (Pinar del Rio City), a very important tourist area in the country. The relationship ...

  • Monitoring radon and its progeny in the environment of the vertical 15 UD Pelletron accelerator facility

    Environmental radioactivity due to radon and its progenies in the ambient air at the vertical 15 UD Pelletron accelerator facility of the Inter University Accelerator Centre, New Delhi, India was evaluated to calculate the annual effective dose to the workers and users. The radon activity was measured with an active monitor. The activity concentrations of the radon progenies were measured ...

  • Vapor intrusion mitigated through solar-powered exhaust systems

    EPA Region 6 undertook a Superfund removal action earlier this year at the Delfasco Forge site in Grand Prairie, TX, to address trichloroethene (TCE) vapor migrating from a groundwater plume. Region 6 and the State had determined after extensive site investigations that technologies such as soil vapor extraction or natural attenuation would require several years to remove or reduce the plume ...

  • Natural radioactivity of some Egyptian building materials

    The study of the radiation hazards from building materials is of interest in most countries. The measurements of natural radioactivity were verified for some Egyptian building materials to assess any possible radiological hazard due to their use. The measurements were performed by gamma-ray spectroscopy using a Hyper-Pure Germanium (HPGe) detector. A CR-39 track detector was used to measure the ...

  • Studies on natural radioactivity of some Egyptian organic and chemical fertilisers

    Radiometry techniques were applied to evaluate the activity and concentration values of 238U, 232Th and 40K in four types of Egyptian made fertilisers. Also, radon and thoron concentration values were estimated for the same samples. The Hyper-Pure Germanium Detection System (HPGeDS) installed at the hot laboratories of Inchas, Cairo, and the Solid State Nuclear Track Detection System (SSNTDS) ...

  • Estimating the spatial-temporal distribution of Radon releases from the K-65 silos

    This study investigates the spatial and temporal distribution of Radon at the Department of Energy's (DOE) Fernald Environmental Management Project (FEMP), in southwest Ohio in 1999. It employs the United States Environmental Protection Agency's (EPA) Industrial Source Complex Short Term 3 (ISCST3) dispersion model, existing monitoring data and Geographic Information Systems (GIS) as tools to ...

  • Environment and Health

    Public concerns, evidence from research and increasing scientific knowledge are all driving widespread discussions on environment and health problems. The issue of environment and health is characterised by multi-causality with different strengths of association. This means that the links between exposures and their health consequences depend on the environmental pollutants and diseases being ...

  • Radon distribution in groundwater of Taiwan

    Radon levels were surveyed in 517 monitoring wells constructed in five major groundwater areas of Taiwan. The radon concentration in groundwater samples varied in a wide range from below the detection limit of 18 pCi/L up to 1,100 pCi/L. A worldwide comparison of reported groundwater radon levels was conducted. Overall radon levels in Taiwan groundwater are relatively low compared to other ...

  • Effects of Headroom on the Performance of the Displacement Ventilation System

    IntroductionIn recent years an increasing amount of health evidence from building occupants has confirmed the existence of sick building syndrome (SBS). This is where occupants within a building begin to report feelings of nausea, headaches and general feelings of illness. Additional symptoms of this health problem include eye, nose and throat irritation, coughing and fatigue. The fact that most ...

  • Effects of chronic radon-related external and internal irradiation: assessment of the dose effect curve below 200 mGy

    The long-term effects of professional exposure to radon are well-known. They result from the combined action on the lung epithelia of α-radiation due to radon inhalation and deposition in the lung of its decay products and external γ-radiation from uranium, thorium and their progeny. According to the guidelines applied by the USEPA and recommended by the ICRP, the maximal exposure in ...

  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...
