Dear Dr. Edlin--

Now I'm afraid we're both confused.
Are you ageréeved because I undpr-or over-
emphasize the hazards of radiation? Or
neither?

My main purpose was to point out the
methodological difficulties we face in try-
ing to formulate reasonable policies for. the
regulation of an innumerable variety of
environmental"additives"., | I am concerned
that chlorine may be as portentous as _radia-
tion; it is astonishing how little investi-
gative work has gone into it. (In fact, we
are finding that DNA is readily chlorinated
by dilute aqueous hypochlorite, and the
chemical and genetic consequences of this,
in microbial test systems are quite fascina-
ting.)

I am also rather confused” about your” “own
position on LSD & cyclamates.~

Perhaps you would consider giving me a
call, and we might clear up some of the com
fusion more quickly. I am also enclosing some
of the other columns in this series, in case
you missed them. The Chronicle runs rather
behind the Washington Post, and it inverted

the sequencem of 170/171. |Piease note that
I have no influence on the headlining.

    

Sineerety,
