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
