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.

但一个意外事实引起我注意：某些矿物质(青铀矿物质、铀云母或钙铀云母)活性比根据其铀或针含量所判断要高。

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.
