Jinsi ya kukokotoa Radioactive Decay

Radioactive Decay ni nini?

Radioactive decay is the spontaneous transformation of unstable atomic nuclei over time. The half-life is the time for half the atoms to decay; after n half-lives, N₀/2ⁿ atoms remain.

Fomula

N(t) = N₀ × e^(−λt) | t½ = ln(2)/λ | N(t) = N₀ × (½)^(t/t½)

N(t): Remaining nuclei at time t
N₀: Initial number of nuclei
λ: Decay constant (s⁻¹)
t: Time elapsed (s)
t½: Half-life (s or years)

Mwongozo wa Hatua kwa Hatua

1N(t) = N₀ × (½)^(t/t½)
2Decay constant λ = ln(2)/t½
3After 1 half-life: 50% remains; 2: 25%; 3: 12.5%
4Used in carbon dating, nuclear medicine, and waste management

Mifano Iliyotatuliwa

Ingizo

Carbon-14, t½=5,730yr, elapsed 11,460yr (2 half-lives)

Matokeo

N = N₀ × 0.25 = 25% of original carbon-14 remains
