The dominant constitutes of soil were SiO 2 , Al 2 O 3 and Fe 2 O 3 . Weak to moderate correlation was observed between elemental composition and activity concentrations of radionuclides. The average annual effective absorbed dose rate measured at 1m above ground due to terrestrial sources was 72.9 ± 1.0 µSvy -1 . The high altitude of study area causes the dominant doses to the public .The radium equivalent activity Ra eq , outdoor and indoor hazard indices we...

anthropogenic radionuclides and associated doses were
determined in soil samples collected from Muree and its
surroundings to provide baseline radioactivity data. High
purity Germanium (HPGe) based spectrometry system was
used for determination of activity concentration. The
activity concentration of 226Ra, 232Th, 40K and 137Cs varied
between 20.0─29.5, 43.4─62.4, 163.0─493.6 and
1.3─54.1Bqkg-1 respectively. Radium equivalent activity
was measured in range 107-148 with average
128.0Bqkg-1.The average annual effective absorbed dose
was found to be 72.9 ±1.0µSvy-1which was comparable to
world’s average. The radium equivalent activity Raeq,
indoor and outdoor hazard indices were lower than the safe
limit of Organization for Economic Cooperation.
