Some specific occupations that have been linked to increased cancer risk include rubber manufacturing, paving, roofing, painting, and chimney sweeping. (cdc.gov)
During the Bush Administration, Office of Information and Regulatory Affairs (ORIA) & Office of Emergency Management (OEM) proposed to weaken radiation standards to levels far outside the risk range and far above the MCLs, placing longstanding EPA fundamental principles at risk. (committeetobridgethegap.org)
Despite the best studies indicating an increased risk from radiation, the standards set by the EPA and other agencies has not been strengthened accordingly. (committeetobridgethegap.org)
The Nuclear Regulatory Commission (NRC) and the Department of Energy (DOE), and ORIA use dose to determine radiation risk standards, which makes it hard for decisionmakers to readily judge the appropriateness of proposed radiation standards. (committeetobridgethegap.org)
This is in contrast to EPA's guidelines which generally rely on risk, and not dose, for setting standards. (committeetobridgethegap.org)
Repeated exposure to imaging radiation accumulates over a child's longer lifetime, posing an increased risk of cancer per dose. (contemporarypediatrics.com)
An instant dose of 100-250 mSv can slightly increase the risk of later developing cancer, but if this dose is spread over time there is less risk of any effect. (world-nuclear.org)
