It was discovered in 1990.

Radium is not a synthesized element. It is one of the naturally occurring elements. It has a limited life time because of the radioactivity though. Radium was first discovered by Marie Curie.
She invented radium and polonium and she was great.

Radium. it's simple
No one 'invented' radium; it is an element on the periodic table. Radium was discovered, however, by Marie Skłodowska-Curie, Pierre Curie and Gustave Bémont in 1898.
Radiotherapy was invented by Wilhelm Rontgen, who invented the x-ray and Marie Curie who discovered radium, which is a material used in certain treatments and in this case, radiotherapy. (Radiotherapy is a mix of an x-ray that projects radium.)

because she invented the radium
