Radioactive Decay & Half-Life

អំពីការពិសោធន៍និម្មិតនេះ

Watch individual nuclei decay unpredictably while the whole sample follows a statistical pattern. Compare small and large samples.

អ្វីដែលសិស្សអាចស្វែងរកបាន

  • What fraction is expected after one, two and three half-lives? Must every sample match it exactly?
  • Each nucleus receives an independent exponential lifetime. N=N₀×2^(−t/T½) is the expected curve. Circles are undecayed parents; crosses are daughters assumed stable. Time units and isotope are illustrative. New sample changes the random seed; reset repeats the original sample.

សំណួរដែលគ្រូតែងសួរ

What fraction is expected after one, two and three half-lives? Must every sample match it exactly?

The expected fractions are 1/2, 1/4 and 1/8. Random samples differ; proportional fluctuations are usually larger for small samples.

About the model

Each nucleus receives an independent exponential lifetime. N=N₀×2^(−t/T½) is the expected curve. Circles are undecayed parents; crosses are daughters assumed stable. Time units and isotope are illustrative. New sample changes the random seed; reset repeats the original sample.
