Thyroid
A : 
A papillary structure with atypical cells and the proliferation of
tumor cells is evident (papillary carcinoma).
B : 
Thyroid tissue (colloid follicles show a regular arrangement, control)
C : 
A nodular tumor is evident in the cervical region.
D : 
- The increase in relative risk at 1 Sv for all ages was 1.15.
- The crude incidence in the control, low-dose and high-dose
groups showed a strong dose response relationship of 1.08, 1.49 and
3.17 per 104 persons per year, respectively.
- The risk was higher in people who were young ATB than in those
who were old ATB.
EĦ§ 
- The subjects were 2,587 people who underwent regular examinations
between October 1984 and April 1987.
- Solid nodule of the thyroid (thyroid cancer, thyroid tumors)
were significantly more frequent among the atomic bomb survivors than
among non-exposed persons, and the number of cases was higher the
higher the dose and the lower the age ATB.
- Autoimmune hypothyroidism was significantly more frequent among
the atomic bomb survivors than among non-exposed persons. Moreover,
the frequency reached a peak at a dose of 0.7 Sv, which was lower
than that in cancer cases.
