Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive colorless odorless tasteless noble gas.It occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead and various other short-lived radioactive elements. Radon itself is the immediate decay product of radium .

Radium and radon are important contributors to environmental radioactivity. Radon occurs naturally in the environment as a result of decay of radioactive elements in the soil and it can accumulate in houses built on areas where such decay occurs. Radon is among the major causes of cancer; it is estimated to contribute to about 2% of all cancer related deaths in Europe. Radium like radon is a radioactive element and it is found in small quantities in nature and is hazardou…

Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table also known as the alkaline earth metals.Pure radium is silvery-white but it readily reacts with nitrogen (rather than oxygen) on exposure to air forming a black surface layer of radium nitride (Ra 3 N 2).All isotopes of radium are highly radioactive with the most …
