Project at a Glance Contents on the CD ROM
  • Protactinium  is a chemical element in the periodic table that has the symbol Pa and atomic number is 91 and it is a malleable, shiny, silver-gray radioactive metal that does not tarnish rapidly in air.
  • It is harmful due to its radioactivity and is also toxic and it is one of the rarest and most expensive naturally occurring elements.
  • A short-lived radioactive metallic element formed from uranium and disintegrating into actinium and then into Lead.
  • Protactinium occurs in vanishingly small quantities in the natural decay chains of uranium and thorium minerals.
  • Most of the protactinium is sourced from thorium that is present in nuclear reactors.
  • Possibilities of using protactinium as a tracer in the fields of geology and pale oceanography have surfaced recently.
  • Protactinium is widely distributed in very small amounts in the earth’s crust,
    and it is one of the rarest and most expensive naturally occurring elements.
  • It does not used for industrial or commercial uses due to its scarcity, expense, and radio toxicity and it only used for scientific research activities.
