Hourly readings of the radon concentration, temperature, relative humidity and barometric pressure will record any unusual fluctuations resulting from Protocol violations. It is extremely difficult to compromise a Radalink test.”
Check sampling rates of the Femto-Tech and Sun-Nuclear products. Also, their accuracy rate. For example, one of them has a 25% margin of error which can make a 4.0 level look like a 3 or a 5.
The only thing that bothers me is the lack of an option to purchase Radalink's equipment. I have used particle counters that have more sophisticated components and they were available for purchase. The ongoing lease is the only problem with Radalink. Bear in mind that calibrations and reporting is included as part of the fee.
