How to Calculate Decay Rate?
Decay Rate calculator uses Decay Rate = -Decay Constant*Total Number of Particles in Sample to calculate the Decay Rate, The Decay Rate formula is defined as is the total activity and is the number of decays per unit time of a radioactive sample. Decay Rate is denoted by D symbol.
How to calculate Decay Rate using this online calculator? To use this online calculator for Decay Rate, enter Decay Constant (λ) & Total Number of Particles in Sample (N) and hit the calculate button. Here is how the Decay Rate calculation can be explained with given input values -> -26 = -0.4*65.
