  • HLRW
  • Thompson makes clear that a partial drain down of a high-level radioactive waste (HLRW) storage pool is an even worse-case scenario than a complete drain down, for air cooling provided by convection currents -- which might otherwise prevent ignition of the irradiated nuclear fuel's combustible zirconium cladding -- is blocked by the layer of water in the bottom of the pool.

  • This was countered by William H. Taft IV, general counsel for the Department of Defense who wrote that Cranston's bill created "the unmistakable impression that exposure to low-level ionizing radiation is a significant health hazard" and would be "damaging to every aspect of the Department of Defense's nuclear weapons and nuclear propulsion programs. (ratical.org)
  • 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)
  • Aside from the most recent fire in Williamsburg, most of these events have gone under-reported and little to no public information was released regarding the potential health and safety hazards presented by these fires. (nag-brooklyn.org)
  • You cannot see or smell radon, but it can become a health hazard when it accumulates indoors. (water-research.net)
  • Concern about granite building materials being health hazard arises due to these factors. (sbwire.com)
  • 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)
  • ATSDR's analyses for the other contaminants detected indicated that no negative health effects are expected from exposure to those contaminants, because people were not exposed at levels high enough to be harmful.Therefore, the other contaminants are not a hazard to public health, and no further action is needed concerning those contaminants. (cdc.gov)
  • toxic
  • Toxic chemicals like dioxins and furans, volatile organic compounds (VOC's) and elevated particulate matter are some of the potentially hazardous chemicals that may be released in the event of a major commercial/industrial fire. (nag-brooklyn.org)

  • Polunium is also radioactive - it is this element, which is produced by radon in the air and in people's lungs, that can hurt lung tissue and cause lung cancer. (water-research.net)
  • DENVER, CO / ACCESSWIRE / December 3, 2018 / Radon is a hazardous and commonly occurring natural gas that is radioactive and believed to be the second leading cause of lung cancer. (oilandgas360.com)
  • Bob Goldstein, US Nuclear CEO, says, "Solving the Radon problem was a natural for US Nuclear since we understand radioactive monitoring and measuring probably better than anyone in the construction industry and we provide some of the most accurate detection devices in the world. (oilandgas360.com)
