What are some things that are in the US that use or need radium to operate?
Radium has very few commercial uses these days, it formerly was used in luminous watch dials, and used in cancer treatment. However, both those uses have stopped because of the environmental dangers. Very little radium is produced nowadays.
That is too bad I need to do a repot on Marie Curie and I don't know what to say for my introduction do you have any ideas?
Do some atomic clocks use Radium ? I think they use Cesium, but I got the same guess from 2 people
For your introduction on Marie Curie, you can start by highlighting her significant contributions to science and her pioneering research on radioactivity. You can mention that she was a physicist and chemist who made groundbreaking discoveries in the late 19th and early 20th centuries. Specifically, you can mention her discovery of the elements polonium and radium, her development of the theory of radioactivity, and her numerous contributions to the field of radiation therapy for cancer treatment. Additionally, you can mention her as the first woman to win a Nobel Prize and the only person to ever win Nobel Prizes in two different scientific fields. This should provide a solid foundation for your introduction.
Regarding atomic clocks, they do not typically use radium. Instead, atomic clocks largely rely on the properties of cesium or rubidium to measure time with extraordinary accuracy. Cesium atomic clocks, in particular, are widely used as the primary standard for measuring time and frequency. These atomic clocks work by measuring the oscillations of cesium atoms at a specific frequency, which provides a stable and consistent time base. So, your initial guess from the two people indicating cesium as the element used in atomic clocks is correct.
