This Article contains three typographical errors.

In the ‘More severe abnormalities 6 months after the accident’ subsection, ‘The overall abnormality rate of the F1 adults was 59.1% (Table 1).’ should read ‘The overall abnormality rate of the F1 adults was 51.9% (Table 1).’ The corresponding number in Table 1 is correct.

In the legend of Figure 4, ‘the right antenna (an arrowhead) was elongated with abnormal structure and colouration’ should read ‘the right antenna club (an arrowhead) was elongated with abnormal structure and colouration’.

In the ‘External radiation exposure’ subsection, ‘a cumulative radiation exposure of 3–55 mSv’ should read ‘a cumulative radiation exposure of 22–55 mSv’.
