Try DOE/EH-0070, "External Dose-Rate Conversion Factors for Calculation of
Dose to the Public".

radionuclides in streams/lakes

	EPA's Office of Radiation and Indoor Air compiles the HEAST Table 4
that
	provides carcinogenic slope factors for external exposure to rads in
soil. 


	Has anyone developed an equivalent listing of carcinogenic slope
factors if
	the source is a waterbody?   
	I am interested in quantifying exposure due to submersion (swimming)
as
	well as from non-swimming activities (eg in a boat, or wading on the
margin
	of the stream).  I assume that the attenuation due to water
eliminates most
	concerns with external radiation while boating or wading?

	Thanks for any input,
