Thyroid cancer incidence rate in the Fukushima Prefecture under the condition of continued ultrasonography surveys is estimated to be increased compared with the incidence rate in 2007 by a factor of 7.4, with a 95 % confidence range from 0.96 to 17.3.

Thyroid cancer incidence rate in the UkrAm cohort during the second to fourth screening is estimated to be higher than the national incidence rate in Ukraine by a factor, fUA, of 3.6, with a 95 % confidence range from 0.5 to 7.9

This choice is supported by the thyroid screening study in Hong Kong (Yuen et al. 2011), in which the ratio for nodules larger than 5 mm and larger than 10 mm is 2.4 (398/169). For tumours, the ratio is 2.2 (11/ 5), nearly equal to that for nodules.

The screenings from October 2011 to March 2013 in the Fukushima Prefecture detected 1,125 nodules larger than 5 mm and 354 nodules larger than 10 mm (Fukushima Medical University 2013b). Correspondingly, the upper boundary of fsp is estimated to be 1,125/354 = 3.2. The lower boundary is assumed to correspond to no additional cases according to differences in the study protocol, 1.0. The factor fsp is assumed to have a symmetrical triangular distribution between these two boundaries with a maximum at 2.1.
