Bananas are somewhat radioactive due to the presence of substantial amounts of potassium. Potassium-40 decays by two

Question:

Bananas are somewhat radioactive due to the presence of substantial amounts of potassium. Potassium-40 decays by two different paths:

19к — Са + В (893%) 40 20 Ca + B 40 40 1šAr + B* 15K gа да

The half-life for potassium decay is 1.3 Ã— 10⁹ years. Determine the rate constants for the individual channels.
