Some fears and concerns have arisen in people's heads whether WI-FI is safe or not when is used in connection for a human being's health. Also these thoughts are stirred up by a recent BBC programme Panorama. At the same time some scientists have declared that they could not find any evidence proving that WI-FI causes any harm or damage to health. Well, we can now investigate this tricky topic in order to find out these proven and those unproven arguments.
Some experiments were undertaken to clear up this situation. Experiment with pupils` reading was performed in one of British schools. The BBC programme Panorama maintains that readings were 600 times below the government's safety limits due to WI-FI radiation. Also the BBC declares that a wireless networks radiation is three times higher than that of a mobile one. From the other side, authorities from scientific society say that the radiation from the laptops is very small. However, better not to encourage children use laptops in their laps when they go online for a long period of time. There is a hot scientific debate with arguments. But, as you know right though thrives on conflict. Now we see that though there is a small radiation from laptops. Then the investigation goes further and Panorama visited one school in Norwich. The experimentation conducted in that school revealed the difference between the WI-FI and mobile radiation. That means that WI-FI signal is three times higher than the beam of mobile radiation.
Let us identify what WI-FI actually means. WI-FI is such a system that uses radio waves of a very low intensity. In comparison with the just common microwave oven that every family has in their houses, the WI-FI radiation intensity is 100,000 times less than that of an oven. Furthermore, if you sit in front of your lap top and receive network by wireless connection for a year then you will have received the same amount of radio waves as that of talking on mobile phone for 20 minutes. So, there is no any evidence what type of radiation has more influence over people's health and life. But, we understand that the radiation does exist and we are curious to discover the way to calculate it.
This is rather a new area for scientists` investigation. That is why research in this particular direction is still proceeding. Taking into account that radio waves or WI-FI have been part of our lives for more than a century then we should already have found some notes or records with regard to any cases of harm, damage or any other negative effects that WI - FI can provoke. Here are some examples that have been represented to the public. The first person who suggested that low-level radiation has an effect on chromosomes or genetic material was a Professor Olle Johansson from the Karolinska Institute in Sweden. However, Professor Will J Stewart from the Royal Academy of Engineering added that science explored that mobile phones` influence over health was negligible and thus assured that people should be calm. Regarding WI-FI, they work on another radio frequencies but the power is very low.
In conclusion, UK Telecom can suggest that opinions are divided into two opposite sides. One side is pro, another is contra. The truth is somewhere in the middle. But, alongside with this delicate issue there are many advantages of using WiMAX connection. This of course is another story and will need to be discussed some other time.
