Study on activity of radium, radon and physicochemical parameters in ground water and their health hazards around Tumkur industrial area.

The activity of radium (226Ra), radon (222Rn) and physicochemical parameters in ground water around study area were estimated by standard techniques. The average values of activity of 226Ra, 222Rn in the study area are higher than the global average but physicochemical parameter are within the safe level. The total dose and ELCR to the workers and publics of the study area are less than the prescribed and accepted level. The industrial activity influences the activity of radionuclides and physicochemical parameter in ground water. The correlation was observed between radium with fluoride, chloride and nitrate. The obtained data are discussed in this paper. [ABSTRACT FROM AUTHOR]
