There is a food irradiation Bibliographic
database at
http://www.nal.usda.gov/fnic/foodirad/intro.html
Principal investigator: Ari Brynjolfsson, Ph.D
The database consists of reports, articles,
books, and book chapters relevant to research and development of irradiated food
from 1947 to 1997. The material was given to National Agricultural Library in
the years 1986 to 1997 from the private libraries of Dr. Edward S. Josephson,
Dr. Eugene Wierbicki, Dr. Walter M. Urbain, and Dr. Ari Brynjolfsson.
