The lead 210 method for dating was applied to firn samples collected from a 5-m pit at Mizuho Station by the 15th Japanese Antarctic Research Expedition. Two series of measurements were undertaken (Po-210 and Pb-210) and the snow accumulation rates were estimated as 19±2cm snow per year from the Po-210 profile and as 20±2cm snow per year from the Pb-210 profile. The net accumulation rate was estimated as 7.8±0.8g water per year assuming that the density was 0.4g per (cm)^3. These values well agreed with the results of previous studies. The lead 210 method could be applied to estimate snow accumulation rate within error of 10% as two sigma.
