Different changes in energy level need different frequencies of electromagnetic radiation. The absorption of radiation can be analysed by an ‘absorption spectrum’. The different black lines ...

Behind the scenes, studies modelling the absorption patterns of 5G electromagnetic ... “We believe the main biological effect of the electromagnetic radiation from mobile phones is a rise ...

the more infrared radiation it gives out in a given time the greater the proportion of emitted radiation is visible light There are no known objects that are perfect at absorbing or emitting all ...

This radiation, which is absorbed by the human body, is measured by the Specific Absorption Rate (SAR) index. The SAR value indicates how much electromagnetic radiation is absorbed by the body ...
