“None of the detected indoor radon concentrations were higher than the reference dose suggested by IR (300 Bq m−3), while 25% of the detected indoor radon concentrations in the bedroom and 29.16% of the detected indoor radon concentrations in the living room were higher than the reference dose suggested by USEPA (150 Bq m−3).”

Structure

Factor: Radon
Setting: home (bedroom), IR
Study design: cross-sectional survey of dwellings: indoor radon measured in the bedroom and the living room of each dwelling and compared against the reference levels of the World Health Organization, the United States Environmental Protection Agency and the national standard of Iran (class 4)
Effect: share-above 25
Caveat: none of the measurements exceeded the Iranian reference level of 300 Bq m−3
