[ RadSafe ] Radioactive Pen

I am looking for info (radionuclide & activity) about a pen that appears
to have been used for marking x-rays. The information on the picture of
the items reads
 
IsofloT   Radiography Pen
CAUTION: Radioactive Ink  (When filled)
Scienceware      Bel-Art Products
 
We contacted Bel-Art products and this item was discontinued and they
can tell us nothing about it. 
 
You can contact me at Bryan-Bionomics at Comcast.Net
 
Thanks
