- Ra-226 was used in numerous medical applications during the 20 th Century as well. It was used in sealed and unsealed sources for cancer therapy applications. Ra-226 was fashioned into various sizes and types of sealed sources, many of which were called “needles” because of their shape. Radium needles and other forms were implanted into cancerous tumors to arrest the cancerous growth. In unsealed form, Ra-226 has been used as a source of radon-222 for inhalation therapy.

Elements for Kids Radium is an extremely rare element on Earth. It is found in uranium ores. It takes about 7 tons of ore just to produce a single gram of radium. It is produced as a byproduct of uranium mining. Because it is so dangerous, only a few ounces are produced each year. How is radium used today? When radium was first discovered it had a number of uses.

Rubidium Rubidium is used as a getter in vacuum tubes because it combines with and removes trace gases. It is also a component in photocells and has been used in making special glasses. Rubidium has been considered for use in ion engines in space shuttles, because it can be easily ionized.Cesium, however, is more efficient.t is a soft, silvery-white metallic element in the alkali group. [See Periodic Table of the Elements ]. Rubidium is the second-most electropositive and alkaline element. As with other alkali metals, it forms amalgams with mercury and alloys with gold, cesium, sodium and potassium.

Radium It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily combines with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra3N2).

- For these reasons, Ra-226 should be regulated consistently throughout the United States. Although many States in the U.S. had previously regulated Ra-226, the NRC lacked comprehensive authority to regulate radium and provide leadership in this area until the EPAct was signed into law in August of 2005.

It's Elemental Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist, in 1898. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it.

- It reduces nitrogen oxides in exhaust gases. Rhodium is also used as catalysts in the chemical industry, for making nitric acid, acetic acid and hydrogenation reactions. It is used to coat optic fibres and optical mirrors, and for crucibles, thermocouple elements and headlight reflectors. It is used as an electrical contact material as it has a low electrical resistance and is highly resistant to corrosion. Biological role. Rhodium has no known biological role.

- Uses. Uranium is a very important element because it provides us with nuclear fuel used to generate electricity in nuclear power stations. It is also the major material from which other synthetic transuranium elements are made. Naturally occurring uranium consists of 99% uranium-238 and 1% uranium-235. Uranium-235 is the only naturally occurring fissionable fuel (a fuel that can sustain a chain reaction). Uranium fuel used in nuclear reactors is enriched with uranium-235.

Radium in Drinking Water Some absorbed radium is excreted in urine. Absorbed radium behaves similarly to calcium and is deposited in the tissues of the body, especially bone. Any radiation received externally through showering, washing, or other uses is not a hazard since alpha particles do not travel through your skin.ost shallow aquifers do not contain higher levels of radium. However, radium has been found in some private and public wells. Radium cannot be seen, tasted, or smelled in your drinking water. Unless your private water supply has been tested for radium, you should not assume your water is radium-free.

Gemstone and Jewelry Glossary Rhodium is a precious metal, a member of the platinum family. Rhodium electroplating is used, especially on jewelry, to provide a surface that will resist scratches and tarnish, and give a white, reflective appearance.Rhodium plating is most often found on white gold.The term white gold is something of a misnomer. Gold is actually yellow, what jewelers call white gold today is an alloy (mixture) of gold and a white metal-usually nickel, silver, or palladium (another member of the platinum family).hodium electroplating is used, especially on jewelry, to provide a surface that will resist scratches and tarnish, and give a white, reflective appearance.

Q & A: Uses and dangers of radioactive elements Some radioactive elements glow because of their radioactive decays. They emit electrons or alpha particles, changing from one kind of element to another, and as the electrons in the atoms rearrange themselves to the new atom's configuration, they emit light. Radium was used for watch dials because it glows green.articulrly nasty radioactive elements include radon and radioactive iodine. Radon is a chemically inert gas with a short half-life (and therefore decays rapidly, emitting radiation faster than other elements).
