→About Decay Constant
===About Decay Constant===
*The '''decay constant''' is denoted by the symbol '''𝜆'''.*The [[Decay (Physics)|'''decay]] constant ''' provides a [[measure]] of the rate at which a [[radioactive]] substance undergoes [[Decay (Physics)|decay]].*Higher [[Decay (Physics)|'''decay]] constant ''' indicates a more rapid [[Decay (Physics)|decay]] process.Used *The '''decay constant''' is used in the calculation of the [[activity ]] of a [[radioactive]] sample.
===Formula===
The '''decay constant''' is related to the [[Half Life|half-life]] of a [[radioactive]] substance by the formula:
*<math>𝜆=\frac{ln(2)}{t_1t_{1/2}}</math>
Where:
t<sub>1/2</sub> is the [[Half Life|half-life]] of a given [[isotope]]
