at a widely different site from the site of infection. Therefore, what 
should be looked for is survival of the genetic activity of a DNA fragment, 
not the coli per se. 
DR. FREDRICKSON: We will ask Dr. Stetten or some member of the commit- 
tee perhaps to comment on those two points tomorrow, Dr. Nightingale. Thank 
you. 
When we convene tomorrow morning we have still two public witnesses to 
hear, and then Dr. Stetten, if he is able, or if anyone is able, to provide 
a summary of our discussion at this point, they will do so, and then we will 
move on for more interchange between the committee itself and the public 
toward the point where the committee members will be asked to provide their 
opinions and recommendations as we move toward the close of the morning. 
This committee is now in adjournment until 9:00 a.m. sharp, tomorrow 
morning. 
[Thereupon, at 5:35 p.m., February 9, the meeting was adjourned, to 
reconvene at 9:00 a.m. the following day.] 
February 10 transcript. 
DR. FREDRICKSON: We will resume our meeting with testimony from 
public witnesses. The number has expanded slightly from my last evening's 
compilation. 
First we will hear from Dr. Zimmerman from the Environmental Defense 
Fund, and Dr. Zimmerman has agreed that he might be able to make this state- 
ment in three minutes. 
DR. ZIMMERMAN: Well, I will see what I can do in this limited amount 
of time. 
I am Burke Zimmerman, a staff molecular biologist with the Smithsonian 
Institution Radiation Biology Lab in Rockville, here representing the Envi- 
ronmental Defense Fund. Most of you should have a copy of our handout.
