Half-Life Calculator – Calculate Radioactive Decay Parameters
The Half-Life Calculator is a powerful tool designed to compute various parameters related to radioactive decay, including half-life (t<sub>1/2</sub>), mean lifetime (τ), and decay constant (λ). Whether you’re a student, researcher, or science enthusiast, this calculator simplifies complex decay calculations by allowing you to input any three known values to determine the fourth.
Features:
✔ Calculate Half-Life: Determine the time required for a substance to reduce to half its initial quantity.
✔ Find Remaining/Initial Quantity: Compute how much of a substance remains after a given time or its original amount before decay.
✔ Time Estimation: Calculate the time needed for a substance to decay to a specific quantity.
✔ Convert Between Decay Parameters: Easily switch between half-life, mean lifetime, and decay constant.
How It Works:
- Half-Life Calculation:
- Enter any three of the following:
- Remaining quantity (N<sub>T</sub>)
- Initial quantity (N<sub>0</sub>)
- Time elapsed (t)
- Half-life (t<sub>1/2</sub>)
- Click “Calculate” to get the missing value along with derived decay parameters.
- Enter any three of the following:
- Decay Parameter Conversion:
- Provide one of the following:
- Half-life (t<sub>1/2</sub>)
- Mean lifetime (τ)
- Decay constant (λ)
- Click “Convert” to instantly get the equivalent values for the other two parameters.
- Provide one of the following:
