reading this section you will be able to do the following:
why Marie Curie was deserving of two Nobel prizes.
what the Curies discovered.
are the Curies?
scientists hard at work discovering radioactive elements were
Polish scientist Marie Curie and her husband Pierre Curie, a French
scientist. While working in France at the time of Becquerels
discovery, they became very interested in his work. They too suspected
that a uranium ore, known as pitchblende, contained other radioactive
elements. The Curies started looking for these other elements,
and in 1898 they discovered another radioactive element in pitchblende.
They named it `polonium in honor of Marie Curies native
homeland. Later that same year, the Curies discovered another
radioactive element which they named radium. Both polonium and
radium were more radioactive than uranium.
For their work on radioactivity, the
Curies were awarded the 1903 Nobel Prize in physics. In 1910,
Marie Curie was awarded the Nobel Prize in chemistry for her discoveries
of radium and polonium, thus becoming the first person to receive
two Nobel Prizes. Since these discoveries, many other radioactive
elements have been discovered or produced. Today many artificial
radioactive materials are produced and put to use in various ways
ranging from medical to industrial. We will continue to talk about
these in the following pages.
and Pierre Curie advanced the study of radiation and discovered
the radioactive materials radium and polonium.
