Younger North Americans are exposed to more radon gas due to occupancy biases within the residential built environment

Abstract Residential buildings can concentrate radioactive radon gas, exposing occupants to particle radiation that increases lung cancer risk. This has worsened over time in North America, with newer residences containing greater radon. Using data from 18,971 Canadian households, we calculated annu...
