How is RF radiation different to the radiation we learn about in school?
What can they penetrate and what can block them?
I looked up articles but i don’t really understand. I’ve been sleeping with my phone under my pillow for 7 years and i need to know if my pillow was enough to block out the RF radiation emitted by my phone or if i have an increased risk in brain cancer.
(Sorry if this is all phrased incorrectly, i’ve been panicking for the past few minutes)
In: Chemistry
Alpha and Beta radiation are just really fast moving Helium nucleus and electrons respectively. Alpha radiation can be locked by just about anything beta radiation has slightly more penetrating power, but still can be blocked by very simple measures.
These types of radiation are the most dangerous when they happen inside the body. Even your skin stops most of the alpha radiation from reaching the more important parts inside your body.
Gamma rays on the other hand is just a type of electromagnetic radiation, it is the same sort of thing as visible light, radio waves, microwaves etc.
They only differ in the frequency/wavelength. As you can easily tell from looking out the window, visible light can penetrate glass panes but not brick walls. And as you can tell by turning on a radio, radio waves do go through walls.
However just because some type of em waves are able to reach you does not mean that they can hurt you and give you cancer.
Due to all the quantum stuff, the waves have more energy the higher their frequency. Even if there is a lot of low frequency waves they won’t be able to do the same damage that even a little high frequency waves could.
The radiation given of by your phone is able to penetrate your pillow, as you can test by calling the phone while it is covered by a pillow. (it will ring.)
However the frequencies used by the phone mean that it won’t have enough energy to be able to knock apart molecules of your DNA and give you cancer.
There are some worries that it might affect you negatively in other ways like heating up etc, but there is not really definitive evidence about that.
