[Effects of gamma-irradiation on the cardiovascular system of sheep].
In experiments with sheep, the response of the vascular system of the mammals to the total exposure dose was studied. A dose increase resulted in a more pronounced impairment of contraction of the cardiac muscle. In response, a compensatory reaction of the peripheral vessels was intensified up to LD50/30. Higher doses led to a complete disorder in the regulatory apparatus of the circulatory system.
