North Texas, USA) Walking Tour of the elements CD. Image adapted with permission from Prof James Marshall's (U. The paint was composed of radium salts and a phosphor and glowed in the dark. All uses of radium stem from its radioactivity. One gram of the element is capable of producing 0.0001 ml (stp) of radon gas. Radium is a hazardous element, and proper ventilation is necessary for storing radium to prevent the build-up of radon gas. Radium is used in industrial production of radon gas. Radium paint was used in the mid 1900s to paint the hands and numbers of some clocks and watches. Radium is a radioactive chemical element and the heaviest of all the alkaline-earth metals in Group Two of the periodic table. Radium is over a million times more radioactive than the same mass of uranium. alkaline earth metal, white but tarnishes black upon exposure to air, luminesces, decomposes in water, emits radioactive radon gas, disintegrated radioactively until it reaches stable lead, radiological hazard, α, β, and γ emitter, exposure to radium can cause cancer and other body disorders. Inhalation, injection, or body exposure to radium can cause cancer and other body disorders. radium (Ra-226), which emits alpha particles and gamma rays and. Radium emits α, β, and γ rays and when mixed with beryllium produces neutrons. Radioluminescence involves the use of a radioactive material that provides a long-term. Surface water is usually low in radium but groundwater can contain high levels of radium depending on local geology. Radium Ra 223 dichloride may cause serious side effects. Radium imparts a carmine red colour to a flame. Get emergency medical help if you have signs of an allergic reaction: hives difficult breathing swelling of your face, lips, tongue, or throat.

It exhibits luminescence, as do its salts it decomposes in water and is somewhat more volatile than barium. Pure metallic radium is brilliant white when freshly prepared, but blackens on exposure to air, probably due to formation of the nitride.
