Temperature readouts may be adjusted to degrees Fahrenheit or Celsius. Radon readouts may be adjusted to either PicoCuries per Liter (pCi/L, US standard) or Becquerels per cubic meter (Bq/m3,World standard). The US EPA recommends action be taken when levels are above 4 pCi/L. Humidity scale is fixed in % Relative Humidity (%rH).
Unlike a test kit, Airthings radon detectors are unaffected by humidity and other radiation.
After 7 days One standard deviation is within 20% of the actual radon level, measured at 2.7 pCi/L (100 Bq/m3).
After 1 month One standard deviation is within 10% of the actual radon level, measured at 2.7 pCi/L (100 Bq/mâ‰¥).
0 ± 1.3 pCi/L: No action needed
1.3 ± 2.7 pCi/L: Experiment with ventilation and sealing cracks to reduce levels
2.7 ± 10.8 pCi/L: Keep measuring. If levels are maintained for more than 3 months, contact a professional radon mitigator
10.8 pCi/L and up: Keep measuring. If levels are maintained for more than 1 month, contact a professional radon mitigator
