Marie Curie studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive. She also found out that:
- you can exactly measure the strength of the radiation from uranium;
- the intensity of the radiation is proportional to the amount of uranium or thorium in the compound - no matter what compound it is;
- the ability to emit radiation does not depend on the arrangement of the atoms in a molecule; it must be linked to the interior of the atom itself - a revolutionary discovery!
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium. Her work aroused the interest of her husband, Pierre Curie, who stopped his own research on crystals and joined the "detective work" with his wife. And Marie was proven right: in 1898 the Curies discovered two new radioactive elements: radium (named after the Latin word for ray) and polonium (named after Marie's home country, Poland).

Dakota people are a Native American tribe and a First Nations band gov’t that
used to dominated the Plains, and they migrated yearly to follow the movements
of American Bison which they hunted for subsistence, while also engaging in
corn and tobacco farming (which they used exclusively for ceremonies). Near
extinction of Buffalo herds vanquished their traditional lifestyle. Wars with
other tribes and enroachement of their lands by whites made sticking to their
traditional life much harder. </span>
