US : " Acceptable" Radiation Limits

in part, require the US Nuclear Regulatory Commission (NRC) to consider
dramatically weakening its radiation protection standard. If federal
radiation limits are gutted in the manner urged by the president, the new
standard could allow four out of five people exposed over a 70-year
lifetime to develop a cancer they would not otherwise get. Contesting the
scientific consensus. Section 5(b) of the executive order—formally titled
“Ordering the Reform of the Nuclear Regulatory Commission”—directs
the NRC to issue a proposed “wholesale revision of its regulations and
guidance documents,” including reconsideration of the agency’s
“reliance on the linear no-threshold (LNT) model for radiation
exposure.” The LNT model maintains that risk from radiation exposure is
proportional to the dose: Even a tiny amount of radiation causes some small
but real increased risk of cancer, and that risk goes up linearly as the
dose increases.
