Dear Mr. Lederberg:

I am enclosing a draft copy of the report "Assessment of
Technologies for Determining Cancer Risks from the Environment."
The report describes what we know about exposures and factors that
are responsible for today’s cancers, methods to identify
carcinogenic substances and to project human risks, and Federal
regulatory policies. Earlier drafts have been reviewed by a
number of governmental, industry, and academic experts, and we are
now seeking additional comments.

I know that this is a terrible time of year to ask for a
review, but we would very much appreciate your reviewing ail or
parts of the report. You may telephone your comments to me at
(202) 226-2070 or mail them. We are coming up against a

reasonably firm deadline, and your comments would be most useful
if they reach us before December 29, 1980.

Sincerley yours,

Michael Gough

Project Director
