While
wireless working is becoming an essential part of our daily life, the
researchers say that there’s no evidence to suggest that Wi-Fi is bad
for health. According to BBC program Panorama, radiation levels from
Wi-Fi in one school is up to 3 times the level of mobile phone mast
radiation.
Panorama visited some school with over 1,000 pupils, in order to compare the level of radiation from a typical mobile phone mast with that of the wireless. The results showed the height of Wi-Fi signal strength to be 3 times higher than the main beam of radiation intensity from a mobile phone mast. Medical physics experts explained that this fact was irrelevant, unless there was any proven evidence of it causing health effects.
Although the readings were 600 times below the safety limits, the reports led to heated debate about wireless use. Some experts claim there needs to be a review of Wi-Fi, because there was evidence that low-level radiation caused adverse health effects. However, a number of experts in the scientific community don’t agree with such assessment, saying that Wi-Fi exposure is usually very small, because the transmitters are low power and far from the body.
Although they can be near to the body in case of a laptop being on one’s lap, the experts suggest that just as parents encourage kids not to use mobile phones they should also encourage them to use laptops on a table instead of their lap, if they are using Wi-Fi for a long time.
The matter is that Wi-Fi is a technique that uses very low intensity radio waves – for example, its radiation is 100,000 times less than that of a domestic microwave oven. Even the Health Protection Agency has confirmed that sitting in a Wi-Fi hotspot for a year equals to getting the same dose of radio waves as making a 20-minute mobile phone call.
