What is radium?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is radiumwhich has developed particularly rapidly in recent years. Do you know about radium?
The official answer: Radium, the elemental symbol Ra, is a radioactive element [1] located in the periodic table of chemical elements at period 7, group IIA, atomic number 88. Pure metallic radium is almost colorless, but exposure to air reacts with nitrogen to produce a black radium nitride (Ra3N2). All isotopes of radium are radioactive, with the most stable isotope being radium-226, with a half-life of about 1600 years and decaying into radon-222. When radium decays, ionizing radiation is generated, causing fluorescent materials to glow. It was a new element discovered by Marie Curie, and the discovery of radium contributed to science.
On October 27, 2017, the List of Carcinogens released by the International Agency for Research on Cancer of the World Health Organization was sorted out and referenced, and radium-224, radium-226, radium-228 and their decay products were in the list of first-class carcinogens.
What’s the application of radium?
Radium emits two kinds of radiation, α and γ, and generates the radioactive gas radon.
Laser rays can destroy and kill cells and bacteria. Thus, it is often used to treat cancer and the like. Also, a mixture of radium salts and beryllium powder [4] can be used as a neutron radioactive source for the detection of petroleum resources, rock composition, etc.
Radium is one of the materials of the atomic bomb. Old-fashioned fluorescent coatings also contain small amounts of radium. Neutron Bombardment Radium-225 can get actinium.
Radium isotopes are used to find uranium in the paleochannel
