Radiolead 210Pb and 210Po/210Pb activity ratios in dogs' hair
The aim of this study was to determine activity concentrations of radiolead 210Pb as well as 210Po/210Pb activity ratios in dog hair. The objectives of this research were also to investigate the utility of domestic animal hair as a noninvasive indicator of metal exposure for radiotoxic, naturally occurring 210Pb and find the correlations between 210Pb concentration in hair and age, gender, hair type or diet of analyzed animals. The highest 210Pb concentrations were measured in a 2-year-old Shih Tzus (9.82 ± 0.53 Bq kg−1 dw−1) and a 2-year-old Bichon Maltese (8.09 ± 0.42 Bq kg−1 dw−1), both longhair males, while the lowest was found in a 15-year-old Yorkshire Terrier (0.44 ± 0.02 Bq kg−1 dw−1), small longhair male as well. As results showed, mainly dog hair color as well as their age and gender influenced the differences in the values of 210Pb concentrations in analyzed hair samples. Also the values of activity ratios of 210Po/210Pb in analyzed dog hair samples were calculated and obtained results were similar to those observed in human hair.
