  • Toxic Substances
  • The federal Agency for Toxic Substances and Disease Registry (ATSDR) has released a final report of the public health assessment (PHA) the agency completed on the Safety Light Corporation Superfund Site located at 4150-A Old Berwick Road, Bloomsburg, Pennsylvania. (cdc.gov)
  • ATLANTA - The Agency for Toxic Substances and Disease Registry (ATSDR) announced that recently discovered evidence suggests Iodine-131 (I-131) releases occurring between 1944 and 1956 from the X-10 Site at the Oak Ridge National Laboratory (ORNL) did not extend beyond the facility boundary at levels that would constitute a public health hazard. (cdc.gov)
  • In the 1990s, federal efforts accelerated with the Food Quality Protection Act, an executive order on children's environmental health, the Agency for Toxic Substances and Disease Registry/Environmental Protection Agency Pediatric Environmental Health Specialty Units, and National Institute of Environmental Health Sciences/Environmental Protection Agency Centers of Excellence in Research in Children's Environmental Health. (aappublications.org)
  • emissions
  • CEQA Statutes Section and Education Code Section contain specific procedural requirements with regard to the siting of school sites near potential sources of hazardous emissions. (docplayer.net)
  • A complex chemical and atmospheric phenomenon that occurs when emissions of sulfur and nitrogen compounds and other substances are transformed by chemical processes in the atmosphere, often far from the original sources, and then deposited on earth in either wet or dry form. (free.fr)
  • humans
  • A hazardous material is any item or agent (biological, chemical, radiological, and/or physical), which has the potential to cause harm to humans, animals, or the environment, either by itself or through interaction with other factors. (ihmm.org)
  • assessment
  • Historical air monitoring data from the 1950s and deer thyroid data collected between 1979 and 1989 were supplied to ATSDR during Public Health Assessment research of I-131 releases from the X-10 Site. (cdc.gov)
  • For more information about I-131 releases and the ATSDR Oak Ridge public health assessment visit http://www.atsdr.cdc.gov/HAC/Oakridge/phact/iodine/index.html or contact Jack Hanley at 770/ 488-0736 or call 1-800-CDC-INFO. (cdc.gov)
  • emergency response
  • State Office of Emergency Services which implements hazardous materials notification programs and provides emergency response services to hazardous materials accidents in cooperation with local emergency response providers. (docplayer.net)
  • Wildland Fire Hazard The California Department of Forestry and Fire Protection provides a variety of fire protection-related services for locations within State Responsibility Areas and through mutual aid agreements with local emergency response providers. (docplayer.net)
  • emit
  • Laboratory equipment and instruments which may emit harmful quantities of a substance during their operation must be provided with an effective local exhaust ventilation system. (worksafebc.com)
  • soil
  • The Hazards and Hazardous Materials section of the EIR also discusses the potential for soil or water contamination that could affect the project. (docplayer.net)
  • Although I-131 released during RaLa processing is no longer present in the environment, the current radioactivity of I-129 in the soil can be used to evaluate past I-131 concentrations. (cdc.gov)
  • estimates
  • Because of the limitations with the currently available data and the large uncertainties associated with the previously modeled I-131 release estimates, the extent to which nearby off-site communities were affected by the I-131 releases in the past can not be determined at this time. (cdc.gov)
  • c The US Department of Transportation estimates that the average distance per shipment of radioactive material is about 55 kilometres, well below the 185 kilometre average across all hazardous materials. (world-nuclear.org)
  • health
  • ATSDR determined that radon gas in the buildings formerly occupied on the site was a health hazard to workers during times the facility was operational. (cdc.gov)
  • 3 The Hazards and Hazardous Materials impact analysis should focus primarily on the potential for development to increase the risk of adverse human health or environmental effects related to the presence of hazardous materials in research and teaching laboratories and in the workplace. (docplayer.net)
  • The field of pediatric environmental health traces its origins to a decision made by the AAP in 1957 to establish a Committee on Radiation Hazards and Epidemiology of Malformations. (aappublications.org)
  • harmful
  • ATSDR does PHAs at a site to find out if people are being exposed to hazardous substances from the site, and if so, whether the exposures are harmful and should be stopped or reduced. (cdc.gov)
  • decay
  • The most common form of decay undergone by Krypton-85 is by the emission of beta particles with a maximum energy release of 687 keV and an average energy release of 251 keV. (chemistrylearner.com)
  • The unusually low energy released in the tritium beta decay makes the decay (along with that of rhenium-187 ) appropriate for absolute neutrino mass measurements in the laboratory (the most recent experiment being KATRIN ). (worldheritage.org)
  • environment
  • 2. In the Superfund program, the existence of a contaminant concentration in the environment high enough to warrant action or trigger a response under SARA and the National Oil and Hazardous Substances Contingency Plan. (free.fr)
