In this article, I wanted to provide a resource to compare and contrast the SAR levels of many popular phones and talk a bit about what Specific Absorption Rate is, and how we can use it.
These published guidelines outlined and defined Specific Absorption Rate SAR as a measure of the rate that body tissue absorbs radiation when you are using a cell phone. They decided that the maximum Specific Absorption rate should be 1. They decided on this amount because of the thermal effects of EMF radiation.
Although all RF radiation has some ability to heat human tissue, these limits did not at all take into consideration the many other harmful effects of EMF radiation such as damage to the body, varying symptoms, cancer, and much more check out other articles on EMF Academy for more on these.
The Specific Absorption Rate that the FCC, with input from many other government institutions, decided on, is defined using an average of a minute phone call with the cell phone held directly to the ear.
One major difference between the phones is that the design is very different. On the Droid 2, there is a ” touch screen, and a slide out QWERTY keyboard. Compare and Contrast – Cell.

Since modern cell phones are used in all sorts of manners, ie speakerphone, scrolling through social media, browsing the web, etc, a base had to be set. SAR levels are always tested while operating on the highest possible power, in order to find and determine the maximum EMF exposure output and the corresponding SAR level.
The phone is placed in various positions on the head and body, including held to both ears, and all measurements are taken and reported to the FCC when the manufacturer is seeking approval. In general, probably not, and here is why.
Like we talked about in the last section, SAR limits that are reported are the maximum possible radiation emitted from the device, however, this level is not what is common with the regular use of the device.
As the FCC puts it on their website: Consequently, cell phones cannot be reliably compared to their overall exposure characteristics on the basis of a single SAR value.
A few other reasons that SAR levels can be unreliable: SAR levels only give us information about how much radiation they emit when in use against the body, but do not tell us about how much radiation they emit when not in use.
For example, cell phones and computers can have a significant impact on male fertility due to constant EMF exposure.
