Our clients in florida should be aware of change in our radon reports.
example: average radon level 2.6 +/- 0.2 pCi/l
Radon Reports will look a little different. Just ignore the =/- after your radon average number.
A 3.9 is a 3.9. They do not get to choose whether to apply the + or to apply the - to make their wallets happy.
A 4.1 +/- 0.2 requires mitigation during a real estate transaction but a 3.9 +/- 0.2 does not.
This is becoming a National standard, so at first there is a bit of “oh crap”, but in reality the +/- have been there all along, it just wasn’t printed. Now we have to print it. It is a natural “wobble” associated with measuring a radioactive substance, whether it is Radon or Uranium.
