Radioactive Decay (Activity)
A = A_0·exp(-lambda_d·t)
What it says
The activity of a sample falls exponentially with time at a rate set by its decay constant.
Symbols
| Symbol | Quantity | Dimension |
|---|---|---|
A | Activity (1/s) | T^-1 |
A_0 | Initial activity (1/s) | T^-1 |
lambda_d | Decay constant (1/s) | T^-1 |
t | Elapsed time (s) | T |
Work it out
Enter what you know. No account needed.
Fill in all but one: A_0, lambda_d, t, A are all empty.
