Abstract：
The present paper pionted out that in the measurement of the number of atomsof a radioactive isotope in a sample at time t₀, the error introduced through the in-accuracy of its decay constant (λ) can be reduced to a much smaller value by thecareful selection of the time of measurement or measurements of its radioactivity ataround one life time (1/λ) after t₀ and doing the calculation.
