Although it is the earliest-issued thesis on the study of computer radiation safety, people paid little attention. In 1983, a Swedish scientist published a pamphlet named Compromising Computer, in which the radiation leakageof computer was mentioned once again. In 1985, a Netherlandish scholar named Ike issued his study report on electromagnetic radiation from video display units of computers at the Third Conference on Computer Communication Safety Protection. At the same time he demonstrated how to use a black and whiteTV set to receive signals from a computer with radiation leakage. His report caused a great reverberation in the world. From then on people began to treat this problem seriously.

这是最早发表的研究计算机辐射安全的论文，但当时没有引起人们的注意。1983年，瑞典的一位科学家发表了一本名叫《泄密的计算机》的小册子，其中再次提到计算机的辐射泄漏问题。1985年，荷兰学者艾克在第三届计算机通信安全防护大会上，公开发表了他的有关计算机视频显示单元电磁辐射的研究报告，同时在现场作了用一台黑白电视机接收计算机辐射泄漏信号的演示。
