A comparative study on potential cytogenetic fingerprints for radiation LET in human lymphocytes.

abstract：PURPOSE:Solar energy has a number of short- and long-term detrimental effects on skin that can result in several skin disorders. The aim of this review is to summarise current knowledge on endogenous systems within the skin for protection from solar radiation and present research findings to date, on the exogenous opti...
