2.2 RADON AND THORON
The chemical element radon has two radiologically important isotopes that occur in nature: 220Rn and
222
Rn. Following popular usage, this document refers to the former as "thoron" and the latter as "radon."
Radon and its short-lived progeny (decay products) are continuously produced by decay of 226Ra, a
member of the naturally occurring 238U series. Airborne concentrations of radon's short-lived progeny
