Comparative dynamics of release from potential chromosome damage observed in mouse bone marrow cells under exposure to low and moderate radiation doses.

摘要

Potential chromosome damage due to radiation was diagnosed by identification of abnormalities of mitosis. The results provided evidence that radiation-induced potential chromosome aberrations (PA) were associated with short-term and long-term repairof DNA. The spectrum of PA increased as the radiation dose increased from 24 to 159 cGy. Short-term PA were induced by 24-75 cGy, and higher doses induced predominantly long-term PA.
