Application and current status of elemental research in radiation protection

With beginning by discussing data sources of the parameters in bio-kinetic models for dose estimation,this article summarizes main applications of elemental studies in radiation protection,i.e.their significance in developing relative parameters of bio-kinetic models and environmental transfer models,and introduces related methods for obtaining some important parameters by using examples in literature.Finally,discusses current status of application for elemental studies in the field of radiation protection.
