Compute exponential decay schedules, remaining quantities, and elimination rates.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Choose Carbon-14, Iodine-131, Caffeine, or enter custom half-life parameters.
Input starting quantity and total elapsed time duration.
Review remaining amount, total decayed percentage, and the 5-cycle schedule.
N(t) = N0 × (1/2)^(t / t_half), where N(t) is remaining quantity, N0 is initial quantity, t is time elapsed, and t_half is the half-life period.
Approximately 7 half-lives reduce a substance to under 1% of its original amount (0.5^7 ≈ 0.78%).
