I am looking for information for performing airborne monitoring for Cl-39. We are operating an accelerator and plan to irradiate liquid Argon for an experiment. This will result in the production of Cl-39 via gamma activation. I expect some of the Cl-39 to change from liquid to gas and become airborne. We have local ventilation that will exhaust this out of the building via a stack. I want to monitor the stack effluents during this operation.
My question is how do I sample this? Normally, I would sample the stack with a filter paper and charcoal cartridge. But with the chlorine being a gas, I'm not sure what collection efficiency I would have.
