Men.o from To: JOSHUA LEDERBERG L R.S. ewis BullmAt Sci RADIATION HAZARDS / yours of 12.17.70 I had meant to s&ay in closer touch with you about your plans for this issue. IN ANY EVENT, it seems to me that it would be unfortunate to continue a debate on a set of pre- mises that are already obsolete (namely that the 170 mr standard is being defacto defended). Also I have every hope that the AEC is going through a crisis of decision that may result in further formalization of their expectations. This does not seem like a good time for a joumnal on a monthly schedule to seize on the issue. But if you do, I hope you will give fair representation to Seaborg's statement -- not only by publishing its import, but by looking for a fair recognition that this is current policy ih the other pieces that you accept (or by appropriati editorial comment if its is ignored. When the d ust has settled, there will be plenty of room for further analysis on the basis of these new presmises. If you are still moving ahead-- do you want to use this particular piece, or suggest any small scale revisions that might adapt it better to your own needs? By coincidence Miss Cullen's letter of 5/4 just arrived. If I can have another month (from now) I will amplify the economic argument; but I will be interested meanwhile in your reactions to edhe above.
