Dispersion of radiocesium-contaminated bottom sediment caused by heavy rainfall in Joso City, Japan - Fig 3

Correlation between count rates inside and outside the car (p = 0.781) (a). Correlation between dose rates in air and count rates outside the car (p = 0.215) (b). The absorbed dose rates in air were calculated using software that implemented the 22 × 22 response matrix method [9]. The slopes of these regression lines were used as the shielding factor and the dose conversion factor, respectively.
