The 40K activity of one gram of potassium

Phys Med Biol. 1997 Feb;42(2):407-13. doi: 10.1088/0031-9155/42/2/012.

Abstract

The activity of 40K in natural potassium as derived from the recent literature varies between 27.33 to 31.31 Bq g-1 of potassium. This paper 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.
