The number of sister chromatid exchanges (SCE) per metaphase was determined in normal human lymphocytes by the Hoechst-Giemsa procedure. UV C irradiation promotes SCE dose-dependent in the range of 0-40 mJ/cm2. No difference of this phenomenon may be observed, compairing young volunteers (20-40 years) with a 60-80-year-old group.
