Half life decay equation
Actually, you don't need to know about radioactive decay constants, λ , "k", etc to do half-life calculations. However, if you must learn about these in school, then .... The average lifetime is the reciprocal of the decay constant as defined here. For example, free neutrons decay with a halflife of about 10.3 minutes. This ... 3925e8d270
