Radioactive Decay Calculator

Calculate quantities, time, or half-life related to radioactive decay using the formula N(t) = N₀ * (1/2)^(t / t½). Ensure Initial and Remaining Quantities use the same units (e.g., grams, atoms, Bq, % etc.). Ensure Half-life and Time Elapsed use the same time unit.

Calculate:

Remaining Quantity (N) Initial Quantity (N₀) Time Elapsed (t) Half-life (t½)

Parameters:

Initial Quantity (N₀) (Unit: e.g., g, atoms, Bq, %)

Remaining Quantity (N) (Must be same unit as N₀)

Half-life (t½)

Time Elapsed (t)

(Use same unit as Half-life)
