放射性半衰期指数衰变计算器
利用 N(t) = N₀ × (0.5)^(t / t_½) 求解衰变后剩余量、初始样本量、经过时间或同位素半衰期。
Amount of substance remaining at time t
Starting amount at t = 0
Total decay duration (same time unit as half-life)
Time required for quantity to reduce by 50%
分步代入计算过程
Exponential half-life decay determines the remaining quantity N of an unstable isotope, drug concentration, or decaying signal after elapsed time t given characteristic half-life t_½.
常见参考标准值
