Radioactive decay follows first-order kinetics: N(t) = N₀·e^(-λt); half-life t₁/₂ = 0.693/λ; λ is decay constant.

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
¹⁴C: t₁/₂ = 5730 years, after 11,460 years → 25% remains
ଫଳ
After 3 half-lives: 12.5% remains

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Assuming linear decay (exponential)
  • Using wrong half-life values

Can decay rate change?

No, radioactive decay unaffected by temperature, pressure, chemical state.
