摘要
///The investigation of natural radioactivity in water environment in the lower reaches of the Dadu River shows that the radioactive level of groundwater in this region is safe with U of 0.16 μg·L-1～1.74 μg·L-1, low Th and Ra of less than 0.016 Bq·L-1～0.031 Bq·L-1. Water level of groundwater changes with water level of the oft-com:office:smarttags" />Dadu River
