(one) radioactivity injury
With the thyroid gland of rat of experiment of X line illuminate, can make an animal produce thyroid cancer. The experiment proves 131 Ⅰ can make the metabolization of thyroid cell produces change, nucleolus is out of shape, the synthesis of thyroid element decreases greatly. Visible radiation causes the unusual division of thyroid cell on one hand, bring about canceration; Make thyroid gland is destroyed on the other hand and cannot produce endocrine element, the hormone of hurried thyroid gland that causes from this (TSH) a large number of exudation also can close to send thyroid cell canceration.
