Discussion of measurement and evaluation of the radiation hazard of personal in mixed field

With the application of electronic equipment, both in the field of life and military, which is filled with the electromagnetic wave with wider frequency and stronger radiation intensity, the electromagnetic radiation hazard of the mixed field caused by the combined work of several launch equipment is becoming more and more prominent. GB 10436-1989[1], GB 10437-1989[2],GJB 5313A -2017[3] and the method801 in GJB 8848-2016[4] all provide the methods for measuring the field strength, limiting requirements and evaluating the effects of electromagnetic radiation. In this paper, combining several standards, and the measurement results of electromagnetic radiation environment in the cockpit during the operation of an equipment of a type of aircraft, the method of measuring and evaluating the radiation hazards of personnel in the mixing field is discussed, further more, this paper discussed the limitation of working hours when people working in the electromagnetic radiation in order to ensure the safety of personnel.
