Easy to insomnia, memory loss

 Easy to insomnia, memory loss, physically weak, fatigue, low immunity, with its growth rate of cancer cells twenty-four times faster than normal.

radiation far away from us in our living environment, radiation is everywhere!

household appliances: televisions, refrigerators, air conditioners, microwave ovens, vacuum cleaners and other

Office equipment: cell phones, computers, copiers, electronic equipment, medical equipment, home decoration

: marble, laminate flooring, wall wallpaper, paint and other

surrounding environment: high-voltage lines, substations, television (broadcast) signal transmission tower

natural environment: sunspots and other electrical appliances

radiation index implementation of radiation index

fifth electrical system, who was named the fifth, and both are seriously overweight, but must draw your attention to the; Samsung exceeded the scope of the above belong, but also your attention; a star is safe, you can relax.

two levels of electromagnetic radiation, in which the unit is working band μT, if the radiation is stronger than in the 0.4μT radiation on the human body has certain hazards, long-term exposure susceptible to leukemia. If the radiation in 0.4μT the following, relatively safe. The radiofrequency unit is μW / cm 2.

1. TV

traditional CRT TV CRT is the first tested. We first tested it to close, within half a meter on the front, the normal boot of the moment, the radiation it produces is 0.12μT, the radiation normal viewing is 0.30μT, change the channel when 0.27μT, standby is 0.11μT, while the side view in the case of normal radiation values are 0.28μT, overall it seems close to the warning value.

because most people watch TV is about 3 m distance, so we have to do the front 3 meters tested and found a high degree of attenuation of radiation: Off, Normal view, change channels, standby are 0.12μT, test results show that the traditional CRT TV will not harm normal viewing. But to our surprise that in a larger radiation intensity behind it, within half a meter after the start of radiation values as high as 4.8μT, but separated by glass, wood, radiation is not reduced, or even across the 10 cm thick Wall radiation value there 0.9μT. If your TV behind the bed facing the bedroom, you had better be careful. However, people usually rest and watch TV at different times, so the problem is not quite large.

look at plasma TV, half a meter at the front, boot, watch, for Taiwan is 0.11μT, standby 0.12μT, side 0.11μT; 3 meters in front, boot 0.12μT, normal viewing is 0.14μT, change channels, standby 0.11μT, watching from the test results than traditional TV, plasma radiation intensity is smaller.

and rear projection TVs, the normal viewing, close to the fuselage 0.12μT, side 0.19μT, followed 0.14μT; the front half a meter at the 0.11μT; positive 3 m 0.1μT.

in the TV series of the most reassuring is that LCD TVs, both positive and half a meter or a positive within 3 meters, instant start, normal view, change channels, standby test results are 0.1μT , and the side only 0.11μT, basically no change in radiation intensity.

test results: comparison of three types of TV, we can easily find, LCD TV, rear projection televisions radiation smallest, slightly stronger than that of radiation, plasma TV, CRT TV more, but mainly in television behind, you are prompted best when viewed at a distance, especially children.

2. DVD players and home theater

home theater popular in recent years, that is, player plus sound system, close to the test results, DVD1.2μT, OK machine 1.2μT, PA 1.24μT, small speakers 1.5μT, large speakers 0.49μT, If open simultaneously, the radiation not small.

it was believed that the larger CRT monitors radiation, in the end is not what we think of that? We first tested it, the display before the close to 1.00μT, display the side close to 0.55μT, take a look at the display in the center, from 0.03 meter, radiation also 0.55μT, is it really like CRT monitors We think so much radiation? To further confirm that we started looking for a safe distance from it and found that when the distance of 0.2 meters, the display in front of the radiation to decay to 0.18μT, it seems as long as the CRT display to maintain a distance of 0.2 meters can be assured that use. Friend asked the audience, and it is not a big CRT TV, like the back radiation, the test and found not significant. Some people like to use the radiation of the screen saver, then it work? We also specifically tested it done, plus screensavers only 10% reduction in radiation, it seems screensavers not effective.

now is an alternative to traditional LCD displays, we also tested it. 0.5 m before the display 0.11μT, start an instant 0.12μT, off 0.11μT, the display side of the 0.5 m 0.12μT, it seems LCD really is quite reassuring.

Let us look at the host desktop computer, in front of 0.17μT, but the host control panel central radiation slightly from the 0.03 meter, 0.26μT; host side 0.29μT, the left side of the central chassis, from 0.03 meter, 0.23μT. Back 0.46μT, but we generally have a certain distance away from the host behind, so little effect. There are instant start, standby is 0.17μT. Also talk about the desktop computer power supply wiring connected state if the re-radiation is 0.47μT, then use the desktop computer so have to keep distance.

However, the next test is not so optimistic, and subwoofer speakers, the central control panel, from 0.03 m, 0.63μT; the right side of the central speaker, from 0.03 m, 5.68μT; radiation but do not small, then it's a safe distance from what is it? After careful testing found that when the distance of 0.4 meters, its radiation to be reduced to 0.17μT. So serious radiation subwoofer speakers, the use of at least half a meter to keep the distance.

eventually, that is the laptop screen 0.1 meters before the 0.13μT, 0.3 meters before the display 0.10μT, the display side of the 0.3 m 0.13μT, above the keyboard 0.19μT, power adapter 0.22μT. Radiation test results show slightly stronger notebook keyboard, power adapter max.

Tip: the radiation is very small LCD screen, CRT display is somewhat larger, but all within a safe range; host behind the larger side of radiation, it is strongly recommended that you not easy to heat, open the chassis to use; subwoofer Speaker severe radiation when used for at least half a meter away; notebook radiation concentrated in the top of the keyboard, using a notebook with the adapter should be the far distance.
