Dear Dr. Lederberg:

At the hearings in Palo Alto about the Rasmussen Report Last week,
you commented on the fact that patients with ankylosing spondylitis might
have a predisposition to cancer, and their radiation risk may not be typical.
T mentioned our studies which showed that the patients not given x-ray had
no excess of cancer. In view of your interest I thought you might Like to
have the enclosed reprints which address this particular issue.

IT am the new chatunan of the National Academy of Sciences BEIR Committee,
to neplace Dr. Arthur Upton, and I will transmit your concerns about the
possible genetic effects of radiation exposure to the committee at our
meeting next week.

Sincerely YOuNs ,
