Frequencies of X-ray-induced chromosome translocations in human peripheral lymphocytes as detected by in situ hybridization using chromosome-specific DNA libraries.

In situ hybridization with chromosome-specific DNA libraries was used to analyse radiation-induced stable translocations in human peripheral blood lymphocytes. These data were compared with radiation-induced unstable-type aberrations (dicentrics) in the same samples. The results indicate that far more stable aberrations are induced by radiation in comparison to unstable aberrations.
