Abstract
FOLLOWING the announcements of Fermi and his collaborators1 on the radioactivity induced in many substances by bombardment with neutrons, we have undertaken some similar experiments. Using sources containing 50–100 millicuries of radon mixed with finely powdered beryllium, we have been able to confirm in general the results reported by Fermi, in addition to obtaining a few results independently similar to some which have since been, or are now being, published by him.
