"Radon Capsule"
Radsafers,
We are attempting to characterize an old radioactive source that goes by
the name of "Radon Capsule." It was apparently manufactured and/or
distributed by the Central Scientific Company. The source appears to be
very old, in that much of the upper half (reddish in color) has physically
deteriorated into small fragments - which are themselves radioactive. The
lower half (black in color) seems reasonably intact. There are a number of
what appear to be micro capillary tubes jutting out of the lower half of
the capsule (radon purge mechanism?). The capsule is about 1" long by a
1/4" wide.
Gamma radiation is definitely present, however, I don't have the
spectroscopy equipment to determine the energy. My guess is that we're
looking at a multi microcurie source of Ra-226.
Have any of you folks run across a "Radium Capsule?"
Regards,
-Erick Lindstrom
