QUOTES: 1. nothing In life is to be feared, it only to be understood. Now is the time to understand more, so that we may fear less.

2. Be less curious about people and mire curious about ideas

Radioactive discoveries:

curie was intrigued by the report of German physicist Wilhelm Rontgen’ s Discovery of X-ray and by the French physicist henri becquerel’ s repot of similar ” Becquerel ray” Emitted by uranium salts.

According to Goldsmith, Curie coated one of the two metals plated with a thin layers of uranium salts.

then she measured the strength of the rays produced by the uranium using instrument designed the faint electrical current generated when the air between two metal plates was bombarded with uranium rays.

she found that uranium compound also emitted similar rays

In addition the strength of the rays remained the same, regardless of whether the compound were in solids or liquid state.


She worked extensively with radium throughout her lifetime, Characterizing it’s various properties and investigating it’s therapeutic potential.

However,her work with radioactive material was what ultimately killed her .she died of q blood disease.
