[Age-related changes in the radiosensitivity of animals and critical cell systems. Survival of stem cells of the small intestine epithelium 4-5 days after death in mice of various ages].
Mice of three strains exhibited similar changes in radiosensitivity tested with a reference to "intestinal" death: juvenile and old animals were more radiosensitive. No age-related changes were detected in radiosensitivity of stem cells of the small intestine epithelium estimated with a reference to average lethal dose D0.
