Re: Creative uses for Contaminated Lead

[Lester.Slaback@nist.gov]

First, given the low lead effective thickness these are of little use for
shielding except for low energy sources. Note that the photon emissions
are negligible so the primary problem is contact beta dose rate.

 Some suggestions:

 - x-ray synchrotrons, i.e., synchrotron light sources. Lots of low E
shielding needed.
     (only useful for the soft xray facilities)
 - for patient shielding (their time of exposure is so low that the added
      exposure is negligible)
 - leaded curtains for portable/makeshift x-ray operations
  - leaded paper wieghts? (minimal contact time)
 - liner for gamma spec shields as part of a graded shield (attn: Fraizer
B.)
 -  add some more inert plastic for beta shielding and use them as
intended.
 - wall shielding in x-ray rooms (multiple layers needed but space should
not be an issue) and
 - momentos to remind folks that the world is radioactive.

 -donate to countries where LNT is a rumor and worker shielding is scarce.
