Dear Radsafe, From: _jpreisig at aol.com_ (mailto:jpreisig at aol.com) . Hey All, Brookhaven Lab's Main Webpage has a link to a story about Ac-225 production, so that plenty of the radioisotope will be available every year in a timely manner. You can read the story yourself. Regards, Joseph R. (Joe) Preisig, PhD
