Most states require certification of radon testers - find them by googling this term and add your state name to the search term - certified radon test providers

Here is a link to a webpage with your state radon office, which typically has a list of certified testers on their website.

Certified radon testers typically charge about $150-250 for an on-site screening plus a long-term test ( a month or two).

Home test kits, which are short term - (1-5 day exposure time) cost about $15-40 for the kit, including test evaluation at a mail-in lab. I would recommend against the so-called self-read kits - they just are not reliable and give a lot of false alarms readings.

I would start with 1 or 2 of the short-term home test kits available at building supply stores and fire/emergency/safety supply stores as well as online, and put them in locations recommended in the instructions. If they test low levels, you are probably OK.

If high, then I would go with a certified radon tester visit to verify the level and get an idea of the extent of remedial measures you might want to install. Remember that radon exposure is a cumulative risk, so a house with young children has a lot more reason to be concerned than a household with only elderly persons. Remember also that if you have a reasonably low but concerning level, increasing exterior ventilation while in that area and limiting hours spent in the lowest levels might mitigate it adequately, depending on your house configuration and whether there are bedrooms on the basement level.
