Attempts to measure the branching ratio of K40 by determining the A40/K40 ratio in potassium minerals of supposedly known age were recently reported by Russell, Shilibeer, Farquhar, and Mousuf [1] and by Mousuf [2]. These results indicated a branching ratio of 0.06±0.006. Other recent determinations of λK/λβ by counting methods [3] and by determining the A40/Ca40 ratio in geologically old potassium salts [4] are in agreement with a value of 0.13.
