	Radsafers:

	I've come across one reference that gives a comprehensive list
of
	external dose factors relating specific activity in soil to the
external
	dose rate received from standing on the surface of the soil.
This
	reference is NUREG/CR-5512 "Residual Radioactive Contamination
from
	Decommissioning".  The values given are for surface sources (in
Sv/d per
	Bq/m3) and 15 cm thick sources (in Sv/d per Bq/m3) for a long
list of
	radionuclides.

	I understand that these factors come from Federal Guidance
Report No. 12
	(US EPA) "Dose Coefficients for External Exposure to
Radionuclides
	Distributed in Air, Water and Soil" by Eckerman and Ryman 1992.

	I have two questions:

	1.How can I get a copy of this Federal Guidance Report No. 12?
(sorry,
	I'm Canadian so I don't know about these things)

	2. Does anyone know of other comprehensive references with this
type of
	information?  I'd be particularly interested in a document from
an
	internationally recognized body such as the ICRP or IAEA.

	Thanks for the help.
