Radio-iodine sampling

[Kim Merritt <merritt9@llnl.gov>]

I have been tasked with bringing some air samplers into service for 
our emergency response program.  We would like to have one of them 
available for doing radio-iodine collection if the unlikely need 
arises.  When the samplers were initially purchased (a long time ago) 
this was the obvious initial intent since they all have the ability 
to hold multiple cartridges as well as the particulate filters.  I 
have both impregnated charcoal and silver zeolite cartridges for 
these samplers.  Since I have never done radio-iodine sampling, I 
would like to know if the cartridges should be used together or 
separately under different conditions.  If both cartridges are to be 
used together what order should they be in in the filter head?  Since 
I will have to generate some sort of procedure for doing the air 
sampling I would also appreciate a copy of an existing procedure any 
of you may have.  If it seems like I am hoping that someone will just 
present me with the complete answer to my problem it is because I am. 
The amount of time that I have to dedicate to emergency response 
preparation is pretty small so all help is appreciated.  Thanks in 
advance for any response.
