I have been discussing with another HI friend of mine in reguards to the purchasing of a Radon measuring device. I have been using the Radon canisters and mailing them in to the lab for work up. I have been very pleased with this process so far and my cost's are what I would call fair including the overnight mailing.
My freinds point is that the machine will cost him around $700 and each year after that aprox. $100 for calubration of the unit.
My concern is that if I use the machine and report the levels of radon am I liable for any miss readings.
My questions are is anyone else using the machines and will it be any better than having a registered lab certify the results with the cans.
Thanks
