[ RadSafe ] Removal of Cs-137 source from an old irradiator

[EDWARD J TRAVERSO]

Hi Maryla
 
I was able to dispose of our old irradiator with very little cost to the university I worked at.  A firm in Canada took possession of it to use the source to make a bug irradiator for sterilization.  Please call me to discuss.  Best regards.

Gentlemen, 

Thank you very much for the tips.  At some point we did contact OSRP, but from what I understand, the removal of our source was not quite consistent with their mission. The irradiator is rather large, about 6 feet tall, which is why we thought we would try to remove the source for disposal, e.g., from behind the shield wall using manipulators.  That is why I was looking for the information on how the irradiator was constructed inside. 

Thanks again,

The very best deal to be had for disposal of these types of items can be found 
at Off-Site Source Recovery Project, OSRP, http://osrp.lanl.gov/.  The cost to 
your facility will be minimal, that is if there is any cost at all.

Hi,
      I had a similar problem 25 years ago involving 200 curies of Co-60 
in an experimental device which I designed and built.  I had a complete set 
of drawings, but I did not try to remove the sources.
      I got a type B shipping container from Chem Nuclear Systems, loaded 
the device, mixed and poured in concrete and shipped for disposal.
      This is expensive and does not help you much.
Good luck,
Ddon Rhodes
