![Page 7: Madame Marie Curie & The Science of Radioactivity By Claire Goelst](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649de45503460f94adc188/html5/thumbnails/7.jpg)
Work with Uranium
• Discovered that if you have a certain amount of uranium, then you get a certain amount of ray intensity, no matter what you did to the material
![Page 8: Madame Marie Curie & The Science of Radioactivity By Claire Goelst](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649de45503460f94adc188/html5/thumbnails/8.jpg)
Uranium Continued
•Marie discovered that there was something going on inside the atom that created the rays, she named this effect “radioactivity”
![Page 9: Madame Marie Curie & The Science of Radioactivity By Claire Goelst](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649de45503460f94adc188/html5/thumbnails/9.jpg)
