She didn't discovered radiation.
In the spring of 1896, Henri Becquerel found a penetrating radiation coming from uranium compounds. The Curies took the next step, showing that these rays depended only on the amount of uranium in the compounds. They thus concluded (correctly) that radiation was a facet of uranium atoms themselves, not the result of chemical interactions.
I'm assuming you mean nuclear radiation, which was discovered and initially experimented with in the late 1800s/early 1900s.

the year 1900
No alchemic symbol for radon; radon was discovered around 1900.
in 1899 by Pierre and Marie curie
Radon was discovered by Friedrich Ernst Dorn, a German chemist, in 1900 while studying radium's decay chain
Yes, Dimitri Mendeleev (1834-1907) was alive during the discovery of radon (1899-1903).
Radon is the heaviest of the inert gases. The inert gases are also known as the noble gases and are the lightest elements.

Immediately after the discovery of the radioactivity of radon, near 1900.

Radon was first discovered by Pierre and Marie Curie in 1899 in France. A year later Friedrich Dorn discovered it.

Radon was discovered by Friedrich Ernst Dorn in 1898. There were several proposed names but finally in 1920 it came to be known as radon.
Because radon has no odor or color.
In 1741, the English metallurgist Charles Wood found platinum from Columbia, South America.
