Radiometric dating
Measure the remaining fraction of a radioactive parent and estimate the sample age.
What to notice
Every halving of the remaining parent adds one half-life to the estimated age.
Key relation
t = T½ ln(N₀/N)/ln2
Try this
Compare 50%, 25%, and 12.5% remaining.
What you can change
- Isotope half-life: 100 to 10000 years
- Parent remaining: 1 to 100 %
