The radium and polonium elements were and still are radioactive elements.
The formula of radium perchlorate is Ra(ClO4)2, but this compound is not still prepared.
discovering radium
Radium is a decay product of uranium and is constantly being produced. U-238 has a half-life of about 4.5 billion years, so there's still quite a bit left of the original amount on Earth.
Before it was known how harmful the radiation emitted by radium as it decays is to living tissue, it was applied to some products such as watch faces for its glow-in-the-dark property. Now we know better. Today, unless you are working in the field of nuclear medicine or you are mining uranium ore, you will not be running into radium.
Radium Institute (now Curie Institute) in Warshaw: 1932 Curie Institute in Paris: 1921
is where Marie curie and her husband discovered the elements radium and polonium but now they have turned it into an institute
1932
the radium institute
radio activity was something she loved to study but she mainly kept her focuses on radium, or the radium institute.
Marie Curie founded the Radium Institute in 1932.
