โฆ Synopsis
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.

## Abstract The utility of the sister chromatid exchange (SCE) assay for human population studies is potentially limited by the variability associated with individual baseline SCE frequencies. This investigation identifies and quantifies the major sources of preparative and biological variation ass
