A radon level of 4.0 pCi/L leads to exposure that equals 200 chest x-rays annually or smoking eight ci******es per day.
At 8.0 pCi/L it's equivalent to 400 x-rays or 16 daily ci******es.
And if your level is 20.0 pCi/L that equals 1,000 chest x-rays per year or 40 ci******es per day.
Don't take on that risk. Mitigate problems and breathe safely.
