Web13 mei 2024 · (1) α = α ∘ e − β t where α is activity of the material at any time t and α ∘ is activity of the material at time you started to measure, t = 0. The constant β depends on several factors including decay process ( e.g., β is not same for U and P o ). We can simplify this as: (2) α α ∘ = e − β t ⇒ ln ( α α ∘) = − β t ⇒ ln α = ln α ∘ − β t Web12 sep. 2024 · How do you calculate the half-life of a drug? Half life. The half-life of a drug is is the period of time required for its concentration or amount in the body to be reduced by exactly one-half. Example 2. Drug B has a half-life of 3 hours. 6hr = 2 half − life = 1800 ÷ 2 = 900 / 9hr = 3 half − life = 900 ÷ 2 = 450 / 40 − 32 = 8ℎ = 480
