As living standards improve, health issues become more and more important. With the expansion and diversification of radio wave usage such as smartphones, mobile phones, wireless LAN, wireless and IC tags in daily life, we are worried that radio waves may not be good for our health, and we question the safety of radio waves. There is a person who has. Machines such as jammers are widely used in many places.
Mobile phone jammers with the ability to block signals are used at test sites as a tool to prevent cheating. However, there is a sentence such as "Interfering devices are harmful to humans." The Ministry of Education reveals its position. This phrase lacks scientific evidence. Mobile phone protection is an effective way to prevent cheating. According to the Ministry of Education, we will announce how to teach you how to use this product. There are various opinions about this case. We interviewed Mr. Chen, who has 6 years of experience in producing and selling GPS jammers. He said, "I touch this machine every day. No problem." Many movie theaters have introduced this device. I installed it and used it. There are no unpleasant situations for the human body in these areas.
I will study it as one of the important issues related to electromagnetic waves in the future. There are many types of "electromagnetic waves". As long as you use the wifi jammer, you have to be affected by electromagnetic waves. There is a theory that electric appliances that are normally used do not affect the human body because they emit only a very small amount of electromagnetic waves. High-intensity microwaves generate heat, similar to microwave ovens, and can affect living organisms. In Europe and the United States, legislation on electromagnetic wave protection standards for the human body and standardization of electromagnetic wave measurement methods are steadily progressing.
In order to use radio waves safely and securely in our daily lives, the Ministry of Internal Affairs and Communications has set standard values for radio wave strength based on the results of domestic and overseas research over the past few decades, and regulated by the Radio Law. doing. Specifically, in places such as mobile phone base stations and broadcasting stations where the strength of the emitted radio waves exceeds the standards of the radio wave protection guidelines, fences will be installed to prevent the general public from entering. I am.
