  • Range of motion assessment of elderly arthritis sufferers at Montana (USA) Radon Health Mines

    Radioactive radon therapy is a little-known pain relief modality in the US, although it is an accepted therapeutic choice in many parts of Europe and Japan. Radon therapy has been extensively studied by European and Japanese physicians and scientists but information about the specific therapeutic applications of radon in the US is limited to anecdotal and ethnographic data. The purpose of this ...

  • 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 ...

  • Child care center hazards result in New Jersey emergency legislation

    Exposure of children and staff in a Child Care/Day Care Center in New Jersey prompted Governor Corzine to introduce emergency legislation for Environmental Hazards. These environmental hazards include air emissions from nearby businesses as nail salons, dry cleaners, industrial facilities, chemical plants, and even trucking facilities. Further, contaminated drinking water and contaminated soil in ...

  • HDPE - A Hydrocarbon Resistant Membrane?

    Most brownfield redevelopment and environmental protection applications require the use of a hydrocarbon resistant membrane.  However, each membrane material will vary in its ability to resist chemical attack and its effectiveness as a barrier to permeation.  It is essential that a barrier material prevents the migration of contaminants, thereby not harming the surrounding environment ...

  • 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 ...

  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • Help protect children from environmental risks

    October is Children’s Health Month. To heighten awareness about environmental issues impacting children, EPA is providing parents and caregivers simple tips they can use to help protect children in their homes, schools and communities.“As both EPA Administrator and a mother, I understand the importance of protecting our children from environmental threats,” said EPA Administrator Lisa P. Jackson. ...

  • New approaches studied to investigate vapor intrusion

    In 2008, EPA Region 9 received an EPA RARE grant (Regional Applied Research Effort) to evaluate three promising techniques for VI assessment of indoor air: (1) using radon as a surrogate for assessing VOC VI; (2) using modified sorbent-based methods for longer, time-integrated measurements of indoor air VOCs; and (3) using building pressure differentials to assess the potential for VI. Available ...

  • Application of Monte Carlo Analysis for Assessing Radiation Doses and Risks to Humans

    ABSTRACTThis BIOMASS Theme 2 report has been produced by the Remediation Working Group, which is concerned with the evaluation of the reliability of dose and risk assessment methodologies applied in support of decisions related to the cost-effectiveness of risk reduction measures within an environmental remediation programme. Scenarios have been developed concerning the site contaminated by an ...

  • Remote control dredge prevents contamination at Fernald, Ohio nuclear remediation site

    When the operations manager at the Fernald, Ohio Super Fund Site Remedial Action Project needed a dredge to remediate sludge from one of four on-site waste (raffinate) pits, they required more than the usual dredging standards. The dredging operation was complicated with the possibility of unknown radon emissions, chemical contamination, and radiation that could be unleashed as material was ...

  • Using Rn-222 to manage the air quality of air conditioned buildings in Hong Kong

    This paper proposes a pragmatic methodology to manage the air quality of an air conditioned building as well as optimizing energy consumption during venting. Radon-222 (Rn-222) is used as a tracer to quantify the specific production rates and resultant losses of pollutants for which the information is important in indoor air quality management. A term, indoor pollutant inventory, is introduced ...

  • Superinsulated Houses

    Superinsulated building is a method of energy-efficient construction that can be adapted to any structure, commercial or residential, in any climate. A superinsulated (SI) home can save 75% of the annual energy costs for heating and cooling compared to a standard home, and is also more comfortable and healthy for the occupants. SI houses can be of any design—Colonial, Victorian, Contemporary, ...


  • Good intentions may result in bad health

    President Obama’s stimulus investments in home energy efficiency may have the unintended consequence of increasing future medical costs. The stimulus bill contains $1500 tax credits for homeowners who install energy efficient doors, windows, and/or insulation. Studies in both the United States and England have shown that these home upgrades can reduce air infiltration by 50% in older homes, and ...

  • Dredging at weldon spring super fund project Morrison Knudsen - St. Charles, Missouri, USA

    Remote controlled Dredging proved to be the best method of removing radioactive sludge from settling ponds of a former uranium processing plant near St. Charles, Missouri. Dredging keeps the material wet and out of contact with the atmosphere throughout the removal and treatment process, eliminating the danger of contaminates becoming airborne. The Weldon Spring Site Remedial Action Project ...

  • Program developed to ensure long-term O&M and performance of vapor intrusion mitigation

    EPA Region 7 has developed a comprehensive VI program to address the installation and long-term operation and maintenance (O&M) of VI mitigation systems, as well as assessment sampling for future systems, in homes near the Chemical Commodities, Inc. Superfund site (CCI). Region 7's VI Program Implementation Manual, which describes decision processes and procedures as well as roles and ...
