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.
