Correlation between incidence rates for influenza and norovirus infection and soil radiation
| Season | 2006–2007 | 2007–2008 | 2009–2010 |
|---|---|---|---|
| Influenza | 0·84** | 0·61** | 0·66** |
| Season | 2006–2007 | 2007–2008 | 2008–2009 |
| Norovirus | 0·61** | 0·72** | 0·71** |
** P < 0·01
Pearson's correlation coefficients are shown for the fluctuating averages of the incidence rates for each dose (rounded to units of 0·01 μGy/h) of soil radiation (<0·15 μGy/h) in Japan.
