Input interpretation
exponential decay
Equation
N/N_0 = e^(-λ T) | λ = log(2)/t_1/2 | N/N_0 | remaining fraction of number of particles T | time t_1/2 | half-life λ | decay constant
Input values
time | 1 second half-life | 1 second
Results
remaining fraction of number of particles | 50% = 0.5 decay constant | 0.6931 Bq (becquerels) = 18.73 pCi (picocuries) = 1.873×10^-11 Ci (curies)
