Marie Curie's Silver Pendant

Origin
Marie Curie was a scientist who conducted research on radioactivity, leading her to be the first woman to win the Nobel Prize, the first person and only woman to win it twice and the only person to win it twice in multiple fields. Her achievements included a theory of radioactivity, techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium.

Effects
Absorbed a lot of radioactivity during Curie's experiments. Wearing the pendant will allow the user to see through solid objects (x-ray vision), but exposes the wearer to high levels of radiation, possibly resulting in cancer or leukemia.
