Differences between the regulations of various states result
to some extent from differences between NCRP's recommended
regulations and AEC "Standards for Protection Against
Radiation"
(1)
California
(a)
No differentiation between exposure levels for
various bedy organs, thus allows less exposure
of the noncritical organs than NCRP
(b)
Air concentrations are established only for alpha
emitters as a class and beta and gamma emitters
as a class.
NCRP sets levels for each isotope.
Thus California permits some higher concentrations
than NCRP and insists on some lower concentrations
(c)
No exceptions for persons under eighteen.
The
AEC permits only one tenth the adult exposure
(4)
No exceptions for persons over forty-five.
The
NCRP would permit double exposure
(e)
(2)
Registration of radiation sources not required
New York
(a)
Several separate regulations
(b)
Permissible exposure levels essentially the same
as recommended by the NCRP
(c)
(3)
NCRP is followed with respect to waste disposal
Pennsylvania and Texas adhere almost to the letter to
NCRP recommendations
