Please see the attached PDF file (assuming the attachment goes through) of
a photo of an item that was found in an old barn in New Hampshire, USA.  It
appears to be a bundle of rubber or plastic tubing with metal clips on the
ends.  The bundle in the photo is approximately 15 cm in diameter, with a
tube thickness of approximately 0.5 cm.  The contact exposure rate is 50
mR/hr, and the isotope was identified to be Ra-226.  Does anyone know what
this might be or where it might have come from?
