Hereof, will a dehumidifier affect a radon test?

If you must test a damp or humid room (over 80% RH) then test only for two days. Dehumidifiers may be operated normally. Moisture may reduce the sensitively of some radon measurement devices. The World Health Organization recommends taking action to reduce radon levels in your home to below 2.7 picoCuries per Liter.

Also Know, is radon worse in summer or winter? Stack effect. The difference in pressure is higher when the difference between indoor and outdoor temperatures is greater. This means that it's at its highest in winter time (next highest in summer), thus contributing to increased radon levels in winter.

what can affect a radon test?

Rain, thunderstorms and high wind can also have an affect on radon testing results. Radon readings have been known to go down when the outdoor wind speeds increase during periods of high humidity. When the seasons change such as fall to winter, radon testing can be affected.

What are dangerous radon levels?

Radon levels are measured in picocuries per liter, or pCi/L. Levels of 4 pCi/L or higher are considered hazardous. Radon levels less than 4 pCi/L still pose a risk and in many cases can be reduced, although it is difficult to reduce levels below 2 pCi/L.
