We’re at an age where information is found and transferred with speeds close to light. You can find nexuses of connection just about everywhere beginning with the omnipresent 3G and 4G connections and ending with wireless hotspots that provide access to the internet 24/7. Unfortunately these high speed transfer and continuous connectivity come at a high price. Have you ever heard about SAR levels? The SAR level will measure the rate at which the body absorbs energy when it is exposed to wireless, RFID, or 3G 4G frequencies. This also includes Bluetooth.
The SAR level comes as an abbreviation from Specific Absorption Rate which is measured in how much energy emitted from wireless networks is entering the human body. Both the European Union and the US have certain regulation about SAR levels emitted from various electronic devices. We all must realize that this energy emitted from Wireless devices or Bluetooth ones is actually radiation of various levels. There has been an increased amount of worry about the high level of radiations that is constantly emitted by such devices (considering that nowadays there are entire cities covered by wireless hotspots). Most of us are familiar with the effect cell phones have over us but very few consider the effect Wireless radiations have over us. This puts another important question. What are the radiation levels of devices such as the iPad which is “addicted” to wireless hotspots?
US law states that a regular device should never exceed 1.6 Watts per kilo which is taken on over 1 gram of tissue. The EU regulators are no less permissive since they allow a limit of 2W/kg but it is over 10g of tissue. There were many debates related to the effects of cell phones or devices on the human body and it has become conclusive that, while the Cell phone is the most devastating, wireless devices or those that use RFID technology have brought their share of damage.
The iPad comes with an average of 1.04 W/kg. Keep in mind that this is the average and the iPads that come with 3G and Wireless have a SAR level of 1.19W/kg. This may not seem much but it is closing in to the limit especially on 3G devices. For iPhones the situation is fairy the same since they have a SAR emission level range between 0.79 and 1.38 watts per kilo. The iPhone 3G older model is the most dangerous by far.
The advantage of the iPad compared to other smartphones is that you’re not exactly holding it to your ear. Since there is a certain amount of distance between you and your iPad, the radiation exposure tends to drop dramatically.
