Condition of voles housekeepers thyroid gland from radioactive territories after padding influences

For detection of stability of animals thyroid gland (TG) after action of the ionizing radiation in small doses experiment on the voles housekeepers living in territories with various level of radiocontamination, with padding not radiating influences (cold and urethanum) was made. Tests applied by us showed that reactivity of animals TG living in different radio of ecological conditions, isn't identical. High stability of TG of voles testing a chronic exposure in small doses to action of padding not radiating factors, in comparison with control animals is found. It is possible to assume that at the long-lived habitat of voles housekeepers population in the conditions of raised background radiation there is a reorganization of work of cells protection system.
