The FCC guide "Specific Absorption Rate (SAR) For Cell Phones: What It Means For You", after detailing the limitations of SAR values, offers the following "bottom line" editorial: ALL cell phones must meet the FCC’s RF exposure standard, which is set at a level well below that at which laboratory testing indicates, and medical and biological ...
The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.
A measure of the heating effect is the specific absorption rate or SAR, which has units of watts per kilogram (W/kg). The IEEE [ 8 ] and many national governments have established safety limits for exposure to various frequencies of electromagnetic energy based on SAR , mainly based on ICNIRP Guidelines, [ 9 ] which guard against thermal damage.
US Department of Energy 2010 dose chart in sieverts for a variety of situations and applications [32] Various doses of radiation in sieverts, ranging from trivial to lethal, expressed as comparative areas Comparison of radiation doses – includes the amount detected on the trip from Earth to Mars by the RAD on the MSL (2011–2013).
Specific absorption rate [ edit ] As of November 2005, (when it was first introduced) the Motorola Slvr L6 ranked as one of the ten highest-radiation phones in the United States at a digital SAR level of 1.58.
English: Radiation Dose Chart by Randall Munroe as part of the webcomic xkcd (SVG version of ). In response to concerns about the radioactivity released by the Fukushima Daiichi nuclear disaster:Fukushima Daiichi nuclear disaster in 2011, and to remedy what he described as "confusing" reporting on radiation levels in the media, Munroe created a chart of comparative radiation exposure levels.

The adoption of the gray by the 15th General Conference on Weights and Measures as the unit of measure of the absorption of ionizing radiation, specific energy absorption, and of kerma in 1975 [17] was the culmination of over half a century of work, both in the understanding of the nature of ionizing radiation and in the creation of coherent ...
