It is concluded that the 36CI ages of the groundwater of the fourth group(Q,) near the mountain and the second-third(Q3-Q,) group in the east of the Baoding area are less than 100k4 that the age of the third- fourth(Q,Q1) group in the east of the Baoding area is about 314.5ha and that of the second-third group in the west of The Cangchou area is less than 100ka.展开更多

Accelerator mass spectrometry (AMS)is the most important tool for detection of naturally produced long-lived radioisotope. Absolute AMS-measurements of ^36Cl require reliable standards for calibration. This original solution of RM12492 was diluted for new AMS standards. All dilution solutions weremade gravimetrically.展开更多
