RE: RADSAFE digest 3303

["North, David" <DNorth@Lifespan.org>]

Your memory is pretty good. I consulted my (probably too) voluminous files.
The date was May 25, 1993, and the speaker was Dr. William Thilley,
Professor of Toxicology and Civil Engineering at MIT. I haven't heard
anything more about it, either. And, yes, Jacquelyn Yanch spoke on BNCT,
also.
