Abstract
The activity of K-40 in natural potassium as derived from the recent l iterature varies between 27.33 to 31.31 Bq g(-1) of potassium. This pa per reports measurements by gamma-ray spectrometry and compares these with independent calculations, yielding values of 30.18+/-0.72 Bq g(-1 ) and 31.00+/-0.33 Bq g(-1) respectively.
