ABSTRACT: With the wide application of electronic products in life, its radiation safety has gradually become the focus of public attention. In order to ensure personal health, equipment safety and electromagnetic environment, as well as to protect the interests of users and consumers, it is necessary to rectify the products with unqualified radiation emission. Through the analysis of the reasons for the excessive radiation emission of electronic products, it can be concluded that the excessive radiation emission of products is usually caused by three factors, interference source, interference coupling path and sensitive equipment. According to relevant national radiation safety standards, this paper used advanced electromagnetic compatibility principles and shielding effect theory to locate the radiation source of electronic equipment, analyzed its radiation characteristics, and took corresponding measures to reduce the radiation emission value of the tested product to within the specified limit, put forward the three major directions for radiation emission rectification at present were shielding, filtering, and isolation, which providing further reference for related research.
