Information @ a Glance

  • Radium is a radioactive element that occurs naturally in very low concentrations (about one part per trillion) in the earth’s crust.
  • Radium in its pure form is a silvery-white heavy metal that oxidizes immediately upon exposure to air
  • Radium was first discovered in 1898 by Marie and Pierre Curie, and it served as the basis for identifying the activity of various radionuclide.
  • Radium-226 is a radioactive decay product in the uranium-238 decay series and is the precursor of radon-222.
  • Radium-228 is a radioactive decay product in the thorium-232 decay series.
  • Radium-226 is the only radium isotope used commercially. Historically, the main use of radium has been as a component in luminous paint used on the dials of watches, clocks, and other instruments, although it is no longer used for Radium this purpose.
  • Urine tests can determine if you have been exposed to radium.
  • Another test measures the amount of radon (a break­down product of radium) in exhaled air. Both types of tests require special equipment and cannot be done in a doctor’s office.
  •  These tests cannot tell how much radium you were ex­posed to, nor can they be used to predict whether you will develop harmful health effects.
  • It is in powder form. Generally used for stickers for wall in homes, dials of watch, textile printing, stickers, notice boards on road. Range of colours:Green,Blue,violet.
  • You can reduce radioactivity in your
    drinking water by selecting one of the following options:
  • 1.Hook up to a municipal water system if this option is available.
  • 2.Install a water softener or ion exchange water treatment system (known as a point-of-entry system).
  • 3.For the average home, this is usually the most feasible and cost effective method
    of reducing radioactivity in drinking water.
  • 4.Install a point of use ion exchange treatment system and use this water for drinking and food preparation.
  • Radium is classified as an "Alkaline Earth Metals" which are located in group2 elements of the periodic table.
  • An element classified as an Alkaline Earth Metals are found in the earth's crust, but not in the element form as they are so reactive.
