Radioactive Decay & Half-Life Calculator
Calculate exponential radioactive decay (N(t) = N0 (1/2)^(t/t_half)), remaining mass, and elapsed half-lives.
Remaining Amount (N(t))
--
25.00% of initial mass (2.0 half-lives elapsed)
How to Use
- Enter the initial quantity, half-life and elapsed time.
- Select Remaining Quantity to view the remaining amount (n(t)).
