The Radon Problem in 14 C Dating

Due to traces of radium and uranium in most 14 C samples, radon appears as a radioactive contamination in the CO 2 prepared by combustion. This contamination must be removed by an active purification prodecure or by storing the CO 2 prior to measurement. No effective electronic discrimination agains...
