It looks like today we’re getting irradiated more than ever. Laptops, tablets, smartphones — we simply can’t live a day without something electronic in our hands. Despite being widespread, all these devices make certain impact on human health. Even different kinds of electric appliances we use every day at home are considered to be unsafe.
Let’s look deeper into the issue. What is really harmful and what is not?
All those blenders, washing machines, etc. really create some magnetic field affecting our organism. But the strength of emissions is different and depends on the kind of appliance. According to scientific research vacuum cleaners and microwaves are among the most irradiating home appliances. At the distance of 30 cm they create alternate magnetic field of 2-20 and 3-8 µT correspondingly. So it’s not recommended to stand close them while they’re working. Then go electric shavers, hair driers and washing machines. Radiation emissions of other electric appliances are hardly noticeable for our health.
Mobile phones are said to be harmful for human body, they supposedly affect our brain activity and even can cause serious illnesses like cancer. Mobile phone producers deny this information while numerous researches contradict their argument.
Emissive power of a cell phone is different depending on the conditions of signal reception. When the signal from the base station is low and weak, radiation emissions can reach 2W, when the coverage is good they decrease up to 0, 01W. The maximum radiation power is emitted during mobile conversations and connection establishment. You can notice it according to the speed of phone battery recharging.
Probably mobile phone boosters are strongly associated with additional radiation emissions because they are not very spread. Research proves that this fear is rather exaggerated. Emissive power of a mobile repeater is 0,1W, just like of an ordinary radiophone we have at home. By the way, the power is divided between a few antennas, which are placed at a considerable distance from the user.
Apart from low emissions a cell phone booster reduces radiations coming from a mobile phone. The purpose of a repeater is to amplify mobile signal in a certain area. Since a mobile device emits heavily in the absence of a strong signal it has emissive power of 2W out of the city and 0,6W in the city. After installation of the booster a mobile phone starts receiving good signal and its emissive power becomes as low as 0,01W. As a conclusion, a mobile booster normally decreases radiation emissions by 60 and out of the city by up to 200 times!
We can hardly imagine a day without a mobile phone, so we cannot escape everyday radiation consumption. But why not to decrease it if it’s really possible?
Another way to increase cellular signal is to build a repeater with your own hands. To do this, you need to install two antennas (both inside and outside - see Fig. 1 and 2) connected by a cable. You can take two J-pole antennas at 900 MHz.
Hi, MyAmplifiers! I need your help to get better cellular signal in my surroundings. I've been always sure that we live in the technological world and problems with bad signal are something from far Middle Ages! But it's annoying for me and hope your devices will be a solution. I looked through some information about mobile boosters and...
It seems to me there is nothing bad for a kid to have a cell phone and when parents have an opportunity to call them. But in my case there’s a bad signal in the forest, where the summer camp is situated and it really makes me nuts. When I want to call my kids I can't do it because of problems with cellular network.
