摘要
论文着重讨论在花岗石的不同岩石类型中,放射性比活度的变化规律及其与放射性矿物锆石的相关关系。研究结果表明,在花岗石中锆石的含量与花岗石的放射性比活度成正相关关系。
Radioactivity of the granite stone is bound up with content and distribution of the radioative mineral in the rock. Zircon is important a radiative mineral. Its content has normal correlation to the specific activity in the stone. Radioactivity is roughly judged by the content of the biotite in the rock if zircons are beneficiatecd in the bi-otites.
