My answer will for sure not help for your US problem, but it should be
helpful for legislators: In Europe the distributors of instruments including
radioactive sources- including Ni-63 ones - have to take the sources back
(and are obliged to dispose them of properly) after the life time of the
instrument and after changes in the configuration. 

What is the problem in the USA to endorse a similar legislation?

Dear RadSafe List:
In the USA, there seems to be a new proliferation of explosive detectors
that use a sealed source for ionization.  I am purchasing a GE
Vaportracer Detector that contains a 10mCi Ni-63 sealed source.  While I
have determined that the device is exempt from licensing and leak
testing requirements, I am worried about disposing of the device at the
end of it's service.   What are the disposal requirements for sealed
sources?  It seems obvious to me that this equipment can't go to regular
landfill and must go to a disposal site for Low Level Radioactive Waste?
Any advice would be appreciated.
