[ RadSafe ] Cs-137 radiography source

[Brian Rees]

I have a researcher that is interested in obtaining (purchasing or leasing) 
a 10-15 Ci Cs-137 radiography source and camera.  We know the people who do 
Ir-192 sources and cameras, but they don't do Cs-137.  Does anyone know a 
source (minor pun!) for Cs-137 radiography?

Sorry I can't add anti-something commentary to feed the seething 
bystanders...but we've got gammas to get....

Thanks,
Brian Rees
