Webhalf-life. In physics, a fixed time required for half the radioactive nuclei in a substance to decay. Half-lives of radioactive substances can range from fractions of a second to … WebTherefore, the half life formula that describes all the exponential decays is: t 1/2= t/ log 1/2 (N t /N 0) Conclusion. Now when we have learned everything about half-life, it shows that half-life has great significance in everyday …
Webhalf-life ( haf'līf) 1. The period in which the radioactivity or number of atoms of a radioactive substance decreases by half; similarly applied to any substance whose quantity decreases exponentially with time. Compare: half-time 2. Time required for the serum concentration of a drug to decline by 50%. WebApr 8, 2024 · The meaning of BIOLOGICAL HALF-LIFE is the time that a living body requires to eliminate one half the quantity of an administered substance (as a radioisotope) through its normal channels of elimination. The meaning of BIOLOGICAL OXYGEN DEMAND is biochemical oxygen demand.
WebThough the biological half-life cannot be expected to be as precise as the physical half-life, it is useful compute an effective half-life from. 1/T Effective = 1/T Physical +1/T Biological. Examples of the half-lives show that biological clearing is sometimes dominant and sometimes physical decay is the dominant influence.
