The α decay rate of Po210 was measured in a film sample (Po210@Bi2O3) and a slice sample (Po210@Bimetal), respectively. The former was used as a reference sample. The half-lives of Po210@Bi2O3 and Po210@Bi metal environments were observed to be (138.40±0.21d) and (138.87±0.87d) at room temperature, respectively. It was found that the half-life of Po210 is consistent with international recommendations within the uncertainty limits, and we did not find any deviation of the α decay rate of Po210 between film sample (Po210@Bi2O3) and slice sample (Po210@Bimetal).
