Moved into new (to us, built in 1980) house 2 years ago. Installed an Airthings radon meter a year ago. Levels get up to 400 Bq/m3 when all the windows are closed. Finally had a radon mitigation system installed. Will hopefully get to much safer level below 100 Bq/m3.
Wow! Hopefully I see results that good.
New construction last year - tested shortly after moving in at ~2500 Bq/m³ ಠ_ಠ
Wired in the fan and now it’s typically reading between 4 and 20 Bq/m³ ( ͡° ͜ʖ ͡° )
So…could you microwave your food by just putting it on the counter? Did your pets count as night lights?
Holy crap!!
