Half-Life Calculator
Calculate half-life, mean lifetime, and decay constant with advanced radioactive decay analysis. Supports activity, remaining quantity, time-to-fraction calculations, and visual decay modeling.
Key Features
- • Convert between half-life, mean lifetime & decay constant
- • Calculate radioactive activity (A = λN)
- • Remaining quantity over time (exponential decay)
- • Time required to reach a specific fraction
- • Unit conversion (seconds, minutes, hours, years)
- • Batch processing (CSV / text input)
- • Statistical analysis (mean, median, std dev)
- • Sensitivity analysis (variation %)
- • Interactive charts (decay curve, comparison, distribution)
- • History tracking with export (CSV, JSON, PDF)
Use Cases
- • Physics & nuclear science studies
- • Radiometric dating (e.g., Carbon-14)
- • Medical imaging & radiotherapy
- • Scientific simulations & modeling
- • Educational tools for exponential decay
How It Works
- • Enter input value (half-life, τ, or λ)
- • Select input type and time unit
- • Choose calculation mode (conversion, activity, decay)
- • Provide optional parameters (time, initial quantity)
- • Analyze results with charts & advanced tools
