| Abstract: |
| Discussed the seasonal trends of the levels and patterns of environmental γ, radiation. The cosine model was used to analyze the monthly average of automatic γ radiation continuous monitoring station from 2005 -2008. Compared with actual values, the fitting curve coincided well with the actual curves. The cosine model can reflect the seasonal variation of radiation levels. |
| Key words: cosine model nuclear power plat γ radiation levels seasonal trends |
