In order to investigate the possible influence of metallic environment on the alpha decay process, we have measured the 147Sm activities in the hosts of metal samarium and Sm2O3 . The 147Sm half-life was found to be (1.06±0.01)×1011 y in metal samarium and (1.07±0.01)×1011 y in Sm2O3 , respectively. No significant change has been observed within the experimental uncertainty. The absolute half-life presented here is consistent with the recommended value.
