Subject: Radioactive graphite bricks

Radioactive graphite bricks

From: Craig Deller <craig>
Date: Saturday, April 24, 1999
The reason I raised this question is that the radioactivity itself
is the historically important part of these otherwise common
materials since it was the first controlled nuclear reaction. Enrico
Fermi and his staff sustained the reaction under the bleachers at
the University of Chicago in 1944, (we all know the story) for the
first time ever, and these are the graphite bricks he used, (along
with other materials being held at Argonne National Laboratory).  It
strikes me as a terrible ethical question. The actual
decontamination would be carried out by Argonne, but I would like to
get a discussion on such an issue.
