如何计算Half Life General

learn.whatIsHeading

A half-life calculator determines the time for any quantity to decrease by half under exponential decay: N(t) = N₀ × (1/2)^(t/T). Applications range from radioactive decay (carbon-14 half-life: 5,730 years) to drug pharmacokinetics (aspirin half-life: 3–5 hours) and population decline modeling.

分步指南

2. 2Calculate remaining amount over time
3. 3Apply exponential decay
