Since then the BEIR and UNSCEAR committees have revised their > cancer risk estimates and NCRP has reduced the maximum permissible > dose limits. > > Dose limits for Research Subjects are linked to occupational > exposure limits and so it follows that they should now be reduced. A > simplified system of dose limits for adults will be suggested. > > As the Japanese A-bomb data has matured, it has become evident > that young children are much more sensitive to radiation induced > cancer than adults. It may be justified to have 3, instead of 2, age > ranges namely 0-5 > yrs, 5 to 18 yrs and over 18 years, with dose reduction factors of 15 > and 10 > respectively for the children that are under 18 yrs of age. > > NOTE: I should disclose that I am a consultant to the FDA.
