Dear listers:

Does anybody know in which chemical compound gamma irradiation sources 
used for material testing, medical use or food irradiation and the like, 
are usually delivered ? I am particularly interested in 137Cs, 60Co and 
192Ir in this context.
Anything known about solubility in water or eventual reactions with air ?
Are such sources being used in ceramic compounds ?

As far as I know the Cs source involved in the Goiânia accident was CsCl 
as powder.

Thanks for hints.
