Figure 4
The number of thyroid cancer case per 105 children in six areas, based on the FSS data, as a function of the hourly air-dose rate. These areas are classified according to the formula shown in Fig. 2 and in Table 1. Poisson error bars are included using the method explained in Fig. 3. We include a straight line using all data points with the Poisson regression method: N = 5.05x + 26.54. We obtain the 95% confidence interval using the Likelihood curve as (0.44, 11.61) for a and (19.78, 34.57) for b.
