palladium seeds

["Nimmo,Elsa (CA35)" <Nimmo_Elsa@Measurex.com>]

A friend will have prostate treatment using surgically implanted
palladium seeds.  

I'm looking for some really basic info -- which isotope, info on
activities typically (?) used, anything on initial dose rates at
patient's skin &  at some greater distance, normal precautions patient
must take after implant.

Anyone know any good references or have time to tell a bit about this,
from a radiation safety perspective? 

Thanks,
