Tom,
All of the above is great info, you might want to weigh your options for method of testing: canister vs CRM (Continous Radon Monitor). Which would best fit your style. I personally chose to put the money out & invest in the CRM. After the test I get instant results via my laptop that includes hourly readout to print & view spikes, I can email that to my client the same day & I don’t have to wait for results from the lab (usually only a couple of days.). This is the way I chose & works fine for me.
Good luck on whatever you choose.
T.J…
What is wind mitigation and can we do it? Terry
Terry… It’s a Florida thing…
BTW. Change your profile so we can see where you are from. 
So- always follow protocol , whats the problem with that? I do it by the book, and i don’t ever need to worry about it later.
