The most dangerous of these is Polonium, the isotope of Po 210 has specific activity of
166 tera Bq for each gram. An ingested microscopic speck of 0.1 microgram would be lethal.
Now radium hasn't practical applications. Uranium has many applications as nuclear fuel and also in nuclear weapons and strong tank armors.
Radium is more reactive than radon. Radium is a highly reactive metal that readily forms compounds, while radon is a noble gas and is less reactive due to its stable electron configuration.
radium
Radium has not its own minerals; radium exist in extremely low concentrations in uranium and thorium ores.
Absolutely none. Radium is element #88, while uranium is element #92. They are two completely different entities. If you are referring to uranium ores, it is a different story. The ratio is about 3 metric tons of uranium to 1 gram of radium. Oxygen and other elements are also present in uranium ore. http://en.wikipedia.org/wiki/Uranium#Oxides

Radium is a decay product of uranium.
She discovered the elements Polonium, which was named after her homeland, and radium. Polonium is 4x more radioactive than uranium and radium is 10x more radioactive than uranium.

Uranium and radium, and a number of others, are natural elements found in the ground, and they are radioactive.
Radium (Ra)
Radium was more or less discovered by accident while the Curies were looking for Uranium in samples of Pitchblende. In 1898, they discovered in tiny amounts, Polonium in July, and Radium in December.
Radium exist in very small concentrations in uranium ores.
Radium exist in uranium ores but in very low concentrations.
