But an unexpected fact was noted: certain minerals( pitchblende, chalcolite, autunite) had a greater activity than might be expected on the basis of their uranium or thorium content.

但是一个意外的事了的注意：某些矿物质(青铀矿物质、铀云母或铀云母)活性比根据其铀或针含量所判断的要。

We found that pitchblende contains at least two radioactive materials, one of which, accompanying bismuth, has been given the name polonium, while the other, paired with barium, has been called radium.

发现沥青铀矿物中至少含有两种放射性物质：与铋伴生的命名为钋，与钡伴生的命名为镭。
