The Research of Sub-picogram Plutonium's Quantitative Analysis by Isotope Mass Spectrometry (In Chinese)

Аннотация

By using active carbon powder as emission matter,the detect sensitivity of ~(239)Pu was 0.5 pg(1±0.15,95% confidence level),improved 20 times compared with the sensitivity 10 pg(1±0.5) of the tradition method.The sub-picogram plutonium sample was determined quantatively by isotope dilution mass spectrometry(IDMS).
