Radium preparations are remarkable for maintaining themselves at a higher temperature than their surroundings, and for their radiations, which are of three kinds: alpha rays, beta rays, and gamma rays.
Radium (usually in the form of radium chloride) is used in medicine to produce radon gas which in turn is used as a cancer treatment.
Radium was originally acquired from pitchblende ore from Joachimsthal, Bohemia (7 metric tons of pitchblende yields 1 gram of radium).

Radium decays into a number of short lived decay products that can usually be expected to be present at, or close to, the same activity as the radium.
The radium was usually in the form of radium sulfate - the latter is less soluble than the other radium salts that were available (radium bromide and radium chloride).
During the 1920s, the radium paint was applied to clock and watch components in a variety of ways: painting it on with a brush, painting it with a pen or stylus, applying it with a mechanical press, and dusting.

 Energy Citations Database (ECD) - Energy and Energy-Related Bibliographic Citations
Renewed interest in lead(II) chemistry stems from a prominent role of the metal as environmental contaminant and also from the recognized diversity of coordination chemistry of the ion, related to the presence of a lone electron pair 6s{sup 2} on the Pb{sup 2+} ion.
The large ionic radius of Pb{sup II} results from the lone electron pair occupying 6s orbital, but the radium decreases to a value compared with that of Pb{sup IV} when the pair enters a hybrid orbital and becomes stereochemically active.
Hancock et al observed a sudden marked increase of stability in a series of Pb{sup II} complexes with macrocyclic ligands where oxygen donor atoms were successively replaced by nitrogens, and attributed that to a change from a stereochemically inactive to active lone electron pair, followed by shortening of the metal-ligand distance.

Barium is used in the manufacture of alloys, soap, rubber, and linoleum; in the manufacture of valves; as a loader for paper; and as an extinguisher for radium, uranium, and plutonium fires.
Estimated releases of barium and barium compounds to the air, water, and soil from manufacturing and processing facilities in the USA during 1998 were 900, 45, and 9300 tonnes, respectively.
At the time of the study, four processes were in operation: "ozide process," which involved blending several grades of zinc oxide; "ozark process," which involved bagging very pure zinc oxide powder; "bayrite process," which involved grinding and mixing several grades of barium-containing ores; and "sher-tone process," which involved mixing inert clays with animal tallow.
