Today radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.
Possible use in radiotherapy of some cancers.
Radium was used in the past for luminescent painting of watches and other instruments, was used in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.
Today radium hasn't many important uses: - radium-beryllium neutrons sources - radium solutions as radon source and standards - possible use in the radiotherapy of some cancers
The first name was radium; some isotopes had in the past other names.
The cost of radium can vary depending on the form and quantity being purchased. However, radium is a highly regulated radioactive element, and acquiring it can be expensive due to its rarity and the associated safety and security considerations. Additionally, the handling, transportation, and disposal of radium require specialized procedures and equipment, further contributing to its overall cost.

Radium is not a common commercial product; radium (generally as radium chloride solution) is sold only to hospitals or specialized and controlled research laboratories.
Radium has today 33 isotopes and 12 nuclear isomers.
We have never stopped using radium. Many "trivial" uses and certain "inappropriate" medical uses were stopped decades ago. While many valid uses of radium have have stopped because better or safer materials (e.g. tritium, cobalt-60, caesium-137, promethium-147) have been found for those purposes, radium still has certain specialized medical and industrial uses where nothing else can yet take its place.
radium-226 isa radioactive element and has the form of a pellet or solution housed with in a ceramic outer housing
The cost of radium can vary based on factors such as the purity, quantity, and source. Radium is a radioactive element with limited commercial uses due to its toxicity and health risks, so it is typically not openly traded on the market. It is often obtained through specialized suppliers or regulated channels for research or industrial purposes.
In the past radium was used for the radiotherapy of some cancers or as a component of luminescent paintings. Now radium has very limited uses: source of neutrons as Ra-Be, source of radon, research laboratories.
The most common state of matter for radium is solid, specifically a metallic solid. Radium is a radioactive element that is typically found in the solid form due to its high atomic number and density.
Radium was discovered in 1889 by French chemesists Marie Sktowska-Curie and her husband. Some common uses for radium is in self luminous paints, "glow in the dark" lights in most watches, and medical use. It is not very safe for medical use and is therefore used mostly by quacks because of extremely dangerously high level of radiation.
