| Background: Due to the presence of radioactive
minerals such as monazite, the beach sand of the
west coast of Kanyakumari exhibits high natural
background radiation. Hair is a good indicator of
radionuclides in the human body. An attempt is
taken to measure the 210Po activity in human hair
samples and the factors affecting it. Material and
Methods: 210Po activity was analysed in 47 individuals
including males and females living in Kanyakumari
district, Tamil Nadu, India. The activities were
measured using a Nucleonix® Radiation Counting
System (RC 605A). Results: The activity was in the
range of 9.89 ± 4.43 to 58.85 ± 6.27 milli Becquerel
per gram. 210Po activity was observed in the hair
samples when compared to the global values were
comparatively higher. Conclusion: Hair samples
obtained from the users of home-made and medicinal
oil had higher concentration of 210Po compared to
that of people using branded oils. These high values
may be attributed to the hair oil usage and this is a
topic of interest for future studies. Iran. J. Radiat. Res.,
