BIOSIS COPYRIGHT: BIOL ABS. This paper reports the environmental radiation level in Beijing. The monitoring sites were set up by netgrid method. In Beijing the grid point-weighted average values for gamma radiation dose and cosmic ray outdoors radiation dose are 56.2 and 32.3 nGy/h, respectively. The area-weighted average values of U-238, Th-232, Ra-226, K-40 and Cs-137 in soil are 19.4, 34.1, 21.4. 662 and 8.3 Bq/kg, respectively. The concentration range of U, Th and Ra-226, K-40 in various waters are 0.12-8.94, 0.02-0.66mug and 6.0-98.1, 19.2-643 mBq/L, respectively. The geographical distribution of the environmental radiation levels is higher in the west-north mountain area and lower in the east-south plain of Beijing.
