The natural Pb2l0 content of ash samples from 18 cadavers has been measured, and an average in vivo content of 0.0 15 picocurie per gram of wet bone is estimated. The contribution of Pb210 to the radioactive dose from natural sources is about one-fifth that from internally deposited Ra226 and its daughters.
