About Nuclear Δ
Nuclear Δ calculates radioactive decay using exponential laws. Compute remaining mass, decay constant, half-life, and activity in becquerels. Suitable for physics and nuclear science learning with clean unit support.
Functions
- Decay law:
N = N₀ · e^(−λt) - Half-life formula:
N = N₀ · (1/2)^(t/T₁/₂) - Decay constant:
λ = ln(2)/T₁/₂ - Activity:
A = λ · N
