1, radium can emit α and γ rays, and produce radioactive gas radon.

2. The rays emitted by radium can destroy and kill cells and bacteria. Often used to treat cancer and so on.

3. The mixed preparation of radium salt and beryllium powder can be used as neutron radiation source for detecting petroleum resources.

Radium is one of the materials of atomic bombs.

5. Searching for uranium in ancient rivers with radium isotopes.

Radium is a highly radioactive element, located in the seventh period of the periodic table of chemical elements, IIA family, atomic number 88, element symbol Ra. Pure metal radium is almost colorless, but it will react with nitrogen in air to form black radium nitride.

The discovery of radium;

After Becker's pioneering observation and research on the radioactivity of uranium, he found that uranium rays, like X rays, can make air and other gases conduct electricity, and thorium compounds were also found to have similar properties. Starting from 1896, Madame Curie and her husband made a systematic discovery, looking for this effect in various elements and their compounds and natural objects.

From 1898 to 1902, after countless times of extraction, nearly one ton of slag was treated, and finally 0. 1 g radium salt was obtained, and its atomic weight was determined to be 226.

The discovery of radium triggered a real revolution in the scientific community. 1903, the curies both won the nobel prize in physics. Madame Curie's great success is by no means easy. It embodies the sweat and tears of the Curie couple, which is the crystallization of their painstaking efforts.
