A re-examination of the half life of lutetium was carried out by an analysis of the probable decay products, and the applicability of this BETA radioactivity for geological dating was tested. In various rare earth minerals the lutetium and hafnium content. as well as the isotopic abundance of hafnium, was determined. In a gadolinite mineral radiogenic Hf /sup 176/ was detected. The mineral age of this mineral was determined. Under the assumption that the possibility of K capture in place of the beta decay or Lu/sup 176/ could be ignored, the half life of Lu/sup 176/ was calculated to be (2.17 plus or minus 0.35) x 10/sup 10/ yr.
