Turning her attention to minerals, she found her interest drawn to pitchblende, a mineral whose radioactivity, superior to that of pure uranium, could be explained only by the presence in the ore of small quantities of an unknown substance of very high activity. Pierre Curie joined her in the work that she had undertaken to resolve this problem, and that led to the discovery of the new elements, polonium and radium. While Pierre Curie devoted himself chiefly to the physical study of the new radiations, Marie Curie struggled to obtain pure radium in the metallic state. This was achieved with the help of the chemist Andre—Louis Debierne, one of Pierre Curie’s pupils. Based on the results of this research, Marie Curie received her Doctorate of Science, and Marie and Pierre shared with Becquerel the Nobel Prize for Physics for the discovery of radioactivity.

她把注意力转向矿物质，发现自己对铀矿感兴趣，这种矿物质的放射性优于纯铀，只能通过矿石中存在少量未知高活性物质来解释。皮埃尔·居里加入了她解决这个问题的工作，并导致了新元素钋和镭的发现。皮埃尔·居里主要从事新辐射的物理研究，而玛丽·居里努力获得纯态的金属镭。这在化学家安德烈-路易·德比尔纳的帮助下实现，他是皮埃尔·居里的学生之一。基于这项研究的结果，玛丽·居里获得了她的科学博士学位，她和皮埃尔与贝克勒尔共同分享了因发现放射性而获得的诺贝尔物理学奖。
