As living standards improve, health problems become more and more important. In daily life, with the spread and diversification of radio waves such as smartphones, mobile phones, wireless LANs, wireless and IC tags, we are concerned that radio waves may be unhealthy or question the safety of radio waves. Machines such as signal jammers are widely used in many places.
At the test site, jammers with the ability to block signals are used as tools to prevent cheating. However, there is a saying that “signal jammers are harmful to humans”. The education department disclosed its position. This language lacks scientific basis. Mobile phone signal jammer is an effective means to prevent cheating. According to the Ministry of Education, we will announce how to use this product. There are various opinions about this situation.
In order to use radio waves safely and reliably, the Ministry of Internal Affairs and Communications has formulated radio wave intensity standards based on domestic and international research results over the past few decades, and formulated regulations based on the Radio Law. Specifically, in places where the intensity of the transmitted radio waves such as mobile phone base stations and broadcasting stations exceeds the standards of radio wave protection standards, jammers and the like will be provided so that ordinary people cannot enter.
