According to radon and its short-lived progeny formation, decay, migration, enrichment regularity and the measured results in our hospital, Tianjin city area of fracture through the zone and recessed regions, such as Jix- ian, Ninghe, Baodi, Wuqing, Hangu and Tanggu areas along the Hai River, higher radon concentrations.
