This means that a person living in an average European dwelling with 50 Bq/m 3 has a lifetime excess lung cancer risk of 1.5–3 × 10 −3. Similarly, a person living in a dwelling with a high radon concentration of 1000 Bq/m 3 has a lifetime excess lung cancer risk of 3–6%, implying a doubling of background lung cancer risk. [63]
