Radium is a radio active element which always undergoes nuclear fission and desentegration, and releases energy in the form of radiation. It is an element. There is no compound in it. It contains atoms of radium.
A new lipstick has been introduced in the market. They have used radium for the glowing effect. The cost of per lipstick is about 950 .Rs.
As radium is radioactive, radium chloride would also be radioactive. Any compounds make with any radioactive material are radioactive, and they cannot be "not" radioactive. Radioactive material doesn't really care if it is "alone" or in compound; it will be radioactive in any case.
Radium chloride is a compound made of radium and chlorine. It is a radioactive substance known for its luminescent properties. Due to its high radioactivity, it is used in scientific research and medical applications, but must be handled with extreme caution.
Radium glows in the dark and is radioactive. When it decays into Radon gas, it emits alpha particles. It is fairly close to its compound radiumchlorite because like radium, it also decays emiting alpha particles. However, radiumchlorite is used to help cure canser. Overal, radium is like its most comon compound but can also have properties not related to its compounds at all.
Radium is not used in asphalt.
If your necklace is marked as containing radium, it likely means that the material used in the clasp or other components of the necklace may be radioactive. This was a common practice in the early 20th century to give objects a glowing effect, however, it is not recommended to wear or handle such items due to the health risks associated with radium exposure.
The first name was radium; some isotopes had in the past other names.
It isn't used for anything anymore--they have better, safer isotopes to do the things radium was once used for.
Radium is not used to produce energy.
Polonium is not used for the treatment of cancers. Radium is used to treat bone cancers.
The controlled variable for making glowing water could be the concentration of the glowing compound (such as a fluorescent dye or chemical) added to the water. By keeping the concentration consistent, you can ensure that any differences in glow intensity are due to the manipulated variable (such as the amount of light exposure or type of light source used) and not the concentration of the glowing compound itself.
Radium was used in the past as a radioactive source in the radiotherapy of some cancers.
