Radon question...

I was wondering if anyone can direct me to the information on how to determine how many radon monitors to use.


Take the nachi course. But I would say two.

That *could *be determined by the State you operate in, and what your definition of a “monitor” is.

How about filling out your location in your profile. Thx.

Use as many as you can afford and maintain calibrated without loosing money from not having one available when needed. Does that answer your question?
