Abstract：
The present paper examines theoretically the way of reducing tha errors introducedby the inaccuracy of the decay constant and measuring statistics in the determinationof the number of the radioactive atoms. It was discovered that the "front-back sym-metrical measurements with life-time as center" (FBSLC) may fulfil this reguirement.Even if the error of the decay constant reaches ±10%, the error introdnced by theinaccuracy of decay constant of the number of the radioactive atoms at zero time cal-culated from the radioactivities measured at zero time and two life-times by takingaverage will still be smaller than 0.1%. Experimental data of ^99mTc radioactive decaywithin measuring statistics verified the above theoretical prediction. Therefore, by FBSLC with measuring time as early as possible, it is possible toreduce the errors introduced by inaccuracy of the decay constant and measuring sta-tistics, so that the results of the absolute measurements may be more accurate.
