What is the Radioactive Decay Calculator?

The Radioactive Decay Calculator helps students, scientists, and enthusiasts determine the remaining amount of a radioactive substance after a given period of time. By entering the initial quantity, the substance’s half-life, and the elapsed time, the tool computes the remaining mass using the standard radioactive decay formula, providing precise results for study, research, or general curiosity.

How to Use:

1. Enter Initial Amount (N₀, g): Input the starting quantity of the radioactive material in grams.
2. Enter Half-Life (t½, years): Input the half-life of the substance in years.
3. Enter Time Elapsed (t, years): Input the duration that has passed since the initial measurement.
4. Click “Calculate”: The tool calculates the remaining amount of the substance using the formula N=N0×(0.5)t/t½N = N₀ \times (0.5)^{t/t½}N=N0​×(0.5)t/t½.
5. Review Result: The output displays the remaining mass in grams. If invalid or negative values are entered, a helpful message guides you to correct the input.
