Abstract
From low frequency electromagnetic wave actual measurement data .There are 5 items over ICNIRP exposure recommends value 833 mG, at 3 cm, they are dehumidifier B, C and microwaves A, B, C. According to the order, the electromagnetic waves are 2223 mG, 1951 mG, 2015 mG, 1332 mG, 1890 mG. The electromagnetic waves would slash reduce up to 98.16% at 30cm distance, the electromagnetic waves data are 57 mG, 71 mG, 111 mG, 45 mG, 34 mG. The results of experimental analysis , the shielding materials of low frequency electromagnetic wave had a best effect, at 3 cm shielding attenuation up to 99.49%. Measuring results ,All appliances of radio frequency electromagnetic wave does not exceed the ICNIRP exposure recommends values, and high frequency shielding material had a best effect for mobile phones, the material shielding attenuation up to 99.82%, and material shielding effect up to 27 dB.
The results of this study show that keeping at least 30cm from electrical appliance or using shielding materials, shielding effect by absorption loss or reflection loss, the electromagnetic waves would significantly reduce. Therefore, we can using these materials on construction, such as coated high frequency paint on the wall can up 16 dB of shield effect , using low frequency shield material to obstruct appliances, the microwaves electromagnetic waves shield attenuation value can up to 1908 mG. The expected results of this study will be used as home life planning and construction materials, to provide users improvement strategy, and helpful to the follow-up research.
