Abstract: From the point of view of electromagnetic radiation safety assessment technology of hot bridge wire electro-explosive devices (EEDs), several test methods of electromagnetic radiation safety assessment of hot bridge wire EEDs  in recent years have been reviewed, and the direction of research to focus on is pointed out. It is pointed out that the use of a high-precision, fast-response new fiber-optic temperature measurement device to monitor the temperature rise response of the hot bridge wire EEDs under external strong field irradiation, through extrapolation to determine the critical stimulus of the tested EEDs, to assess the electromagnetic radiation safety of the hot bridge wire EEDs is an effective measure to break through the bottleneck of the existing test and evaluation technology; as the response time of the  bridge wire is much shorter than that of the fiber optic temperature measurement device, to accurately measure the temperature, further study be made should to solve this prolblem, thus to meet the practical needs of the actually installed hot bridge wire EEDs’  electromagnetic radiation safety assessment.
