^<210>Pb, ^<210>Po, ^<232>Th, ^<230>Th, ^<228>Th, ^<238>U and ^<235>U and ^<234>U in Geological Survey of Japan manganese nodule standard rock sample JMn-1 were determined by radioactive isotope dilution/alpha ray spectrometry. Extraction chromatography, anion exchange chromatography and solvent extraction were applied to the analysis. The analytical results of Th and U in JMn-1 were in agreement with the literature values determined by ICP-MS (inductively coupled plasma mass spectrometry) or INAA (instrumental neutron activation analysis). It was found that the concentration of ^<21o>Pb in JMn-1 was higher than that in other certified reference materials for environmental radioactivity. JMn-1 proved to be useful for quality control sample in the analysis of environmental radioactivity.
