Air Sampling

Radsafers

Tim Knapp, speaking of air sampling for radioiodine with successive charcoal filters, wrote:  Over the past year I have run into 3 occasions where the counts in the second filter are almost equal to those of the first.

In a similar vein, does anyone have experience that they could share concerning observed partitioning between a particulate pre-filter and a silver zeolite or charcoal filter when sampling for radioiodine, or even a three-part filter train with a pre-filter, silver zeolite, and charcoal?
