" Its appearance is almost pure white, but it readily oxidizes on exposure to air, turning black.

- Formerly used in self-luminous paints for watches, aircraft switches, clocks, and instrument dials. More than 100 former watch dial painters who used their lips to shape the paintbrush died from the radiation. Soon afterward, the adverse effects of radioactivity became widely known. Radium was still used in dials as late as the 1950's. Objects painted with this paint may still be dangerous, and must be handled properly. Although tritium's beta radiation is potentially dangerous if ingested, it has replaced radium in these applications.

- When mixed with beryllium it is a neutron source for physics experiments.

- 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 also put in many foods for taste and as a preservative, but also exposed many people to radiation.
223Ra is currently under investigation for use in medicine as cancer treatment of bone metastasis.

- At the turn of the 20th century radium was a popular additive in products like toothpaste, hair creams, and even food items due to its supposed curative powers. Such products soon fell out of vogue, and were prohibited by authorities in many countries, after it was discovered they could have real and serious adverse health effects.

- Spas featuring radium-rich water are still occasionally touted as beneficial, such as those in Misasa, Tottori, Japan. "

Okay,, sweetie, no stupid answers.

All elements heavier than lead, (element 82 Pb) on the periodic table are radio-active. (look up Periodic Table, and click on one of those--- one of them has GOT to show you a table of all the elements... (I'll let you do the grunt work of looking up atoms, molecules, elements, radioactive, particles,etc., and any other word I use here). This means that all of them emit some sort of particle that reduces their mass (weight) Some of these radioactive elements last for years, and others remain intact for only seconds, before they disintegrate to the next one lighter on the list (closer to 82) Radium is one of those, and how long a bunch of radioactive stuff remains radioactive depends upon the half life of each of the elements as they disintegrate. If you let enough time go by (in some cases hundreds of thousands of years) the pile of stuff you had in front of you would become lead) Some of those elements that you see above element 82 (lead) are man made, and do not exist in nature, and some are so unstable that when they ARE put together by man, to be in the area would give you radioactive poisoning, unless you were wearing protective clothing, or putting them together with robots under water, which is often done... (radioactive poisoning -- not a cool thing to die of)

So, radium is not usually found in any large quantity in anything you or I could dig up. { Google Marie Curie -- she and her husband fiddled around with radium in the early 1900's. She eventually died of the effects of radium poisoning (a cancer) and he would have as well had he lived long enough --- as I remember he was run over by a horse and carriage and died. Even some of her sons and daughters who were working on their projects died of cancers caused by radioactive poisoning....}

Hope this helps?

Pitchblende, the uranium ore. Marie and Pierre Curie, the first to isolate radium, extracted a very small amount of radium from a very large amount of this ore.

Element Radium - Ra
Comprehensive data on the chemical element Radium is provided on this page; including scores of properties, element names in many languages, most known nuclides of Radium. Common chemical compounds are also provided for many elements. In addition technical terms are linked to their definitions and the menu contains links to related articles that are a great aid in one studies. http://environmentalchemistry.com/yogi/periodic/Ra.html#Physical

Do you mean where is it found? Within Uranium ore--in trace amounts.
