Abstract: This paper briefly describes the method of estimating skin dose by skin contamination level. Taking surface pollution measuring instrument 6150AD5+6150AD17 as an example, the conversion relation between the monitoring value and contamination level is derived. According to the management requirements of body surface contamination in China and internationally, the definition, classification method and response strategy of the human body surface contamination event based on the monitoring value of 6150AD17 are given. Finally, some suggestions on evaluation index of surface pollution management are given.

Key words: personnel body surface contamination, skin dose, response to specified levels
