What is the Decay Constant?
The decay constant (λ) is the probability per unit time that a radioactive nucleus will decay. It is unique for each radioisotope and is independent of the sample size.

The decay constant determines:
Decay constants are used in:
Decay constants can be determined by:
N = N₀e^(-λt)
λ = ln(2)/t₁/₂
A = λN
