The decay of ~(99m)Tc source was used to verify experimentally that in the measurement of the number of atoms of a radioactive isotope in a sample at time t_0, the error introduced through the inaccuracy of its decay constant can be reduced to a much smaller value by the careful selection of the time of measurement or measurements of its radioactivity at around one life time (1/λ) after t_0 and doing the calculation.

本文用~(99m)Tc源的衰變實驗證明了：在測量一個樣品中在t_0時的一種放射性同位素的原子數(shù)時只需精心選擇一次或多次測量其放射性的時刻在t_0后約該同位素的一個壽期(1/λ)18禁止网站观看大全，并進(jìn)行計算91极品福利精品国产，則由它的衰變常數(shù)或其半衰期(T1/2)的不準(zhǔn)確性而引進(jìn)的誤差可以被降低到較小值。
