[The early and late reactions of the thyroid-gonadal link in rats of different age groups to the action of ionizing radiation].

Pubertal and prepubertal rats were exposed to single (at doses of 0.1, 1, 10 Gy) or fractionated (at total doses of 1 and 10 Gy) X-ray irradiation. It has been shown that the irradiation is accompanied by the one-way phasic changes of thyroid and genital glands independently of the animals' puberty. Remote oppression of activity of the studied glands is the distinctive feature of these changes.
