Abstract

The infant (0.5 month) and adult rats (2.5, 6 and 15 months, respectively) were exposed to single γ-ray neck irradiation (0Gy, as control, 0.5Gy, 2Gy, 4Gy, 8Gy, 16Gy). Some morphometric parameters of thyroid gland were measured under light microscope at 6 weeks after exposure. The results showed that the infant rat thyroids changed signiﬁcantly after 0.5Gy, whereas the adult thyroids expressed the similar response after more than 2Gy. Analysis of these data suggested that the infant thyroids were more radiosensitive than the adult ones.
