摘要：
The ratio of the air pollutants generated on the Chinese continent and transported to Japan across the Sea of Japan was estimated quantitatively by the 222Rn concentration changes at Tonghae (South Korea) and Oki (Japan). It was found that diurnal variations were clearer at Tonghae than Oki. By comparing the baseline trends, which are day-to-day trends of daily minima at these two stations, pollutants in the continental air mass were found to be diluted to 40% during their transport over the Sea of Japan in the winter season.
