摘要:

本文提出了低本底高品质因数液体闪烁计数系统的一些技术关键。根据这些关键,本实验室达到了使测年上限好于30000年的水平。与著名的Beckman LS9800液闪相比较,证明了本系统是测量¹⁴C地质样品的一种高性能且价格便宜的仪器。

A LIQUID SCINTILLATION SYSTEM FOR MEASURING ¹⁴C AGE

Abstract:

This paper presents some technical keys of the liquid scintillation counter with low-background and high-quality factor. By using these keys, a better than 30000 years level can be obtained in measuring ¹⁴C samples. Compared with the well-known Beckman LS 9800 Type Liquid Scintillation System, the system has a high performance at a lower price for measuring ¹⁴C geological samples.
