Upon prolonged irradiation, human stem cells' defenses are activated

(Moscow Institute of Physics and Technology) Researchers discovered that ionizing radiation causes a cell cycle delay, which leads to faster repairs of radiation-induced DNA double-strand breaks, with fewer errors. It is unclear what the health implications are, particularly how this affects the risk of developing cancer, but this results could become the basis of further research into double breaks in stem cells and their effect on tumor formation.
