"Radio Wave Protection Guidelines" (Telecommunications Technology Council Report, Consultation No. 38)
As shown in the Guidelines for the Protection of the Human Body When Using Radio Waves (June 1990), which provides protection methods to reduce the strength of the electromagnetic field irradiated to the human body, electronic devices are generally manufactured with consideration given to their effects on the human body. The amount of radiation to the human body is not large because the electromagnetic waves are manufactured and used, but if you continue to work near electronic devices that emit electromagnetic waves continuously for a long time every day, the amount of radiation to the human body will be further reduced. It is desirable to

When the electromagnetic shielding effect was measured in the wavelength band of kHz to 1 THz, a dB value of 50 dB was obtained, revealing a large electromagnetic shielding effect. Measurement was performed using the Advantest method. That is, a sample was installed between a transmitting probe antenna and a receiving probe antenna in a shield box, and the attenuation rate (dB) was determined from the intensity ratio of the transmitted electromagnetic wave and the received electromagnetic wave. The measurement frequency is 1kHz
The measurement was performed by continuously changing the frequency between 1 THz and 1 THz. The values of the attenuation rate (dB) mentioned above are 1kHz, 1MHz, 1GH
It is the average value of the attenuation rate (dB) at four points of z and 1 THz. The same electromagnetic shielding fabric was used in the following examples, and the same attenuation rate (dB) was obtained.
