Radioactivity monitoring in environmental water and air around QNPP
چکیده انگلیسی
Results of environmental radioactivity monitoring around Qinshan Nuclear Power Plant (QNPP) are reported in this paper. From 1992 to 2005, concentrations of 90Sr, 137Cs and 3H in terrestrial freshwater are (4.4±1.7) mBq
- L−1, (0.3±0.1) mBq
- L−1 and (1.6±0.5) Bq
- L−1, respectively, and (2.8±2.4) Bq
- L−1 of 3H in rainwater. Concentrations of 90Sr, 137Cs and 3H in the seawater samples collected from sea area nearby QNPP are (5.4±4.1) mBq
- L−1, (0.7±0.2) mBq
- L−1 and (1.0±0.5) Bq
- L−1, respectively. Concentrations of 90Sr, 137Cs and 3H in the total waste water discharged from NPP-I are (4.0±1.8) m Bq
- L−1, (1.0±0.5) mBq
- L−1 and (2.8±2.2) Bq
- L−1, respectively, and (1.4±0.4) Bq
- L−1 of 3H in seawater sampled from No.1 outlet. Atomspheric 3H concentration in 1993 ∼ 2005 at two monitoring sites is (78.9±96.3) and (64.2±40.2) mBq
- m−3, respectively, with an increasing trend after 2003. Atmospheric 14C concentrations at the two sites are in the same levels as the background and data of the reference site.
