New cyclotron engineer here. We are about to run some new lines into hot cells. Typically we have ran Teflon tubes but these are accused of raising the cold mass for 18F. Looking at changing over to a polypropylene tubing. Wondering if anyone can tell me if that is what is used at other facilities, where you get it, how often you replace it? I know it is dependent on exposure but looking for info.

Thanks!
