Abstract: This paper introduced an application of the oxygen-bomb method for ¹⁴C monitoring in biological samples from Qinshan Nuclear Power Base,analyzed advantages of this method. The monitoring results over the years for ¹⁴C in biological samples from the base were then analyzed. This study may provide reference in formulating the new national standard of ¹⁴C Monitoring Method for Biologic Samples.

Key words: Qinshan Nuclear Power Base, biological samples, ¹⁴C, oxygen-bomb method, liquid scintillation spectrometer
