im not sure if this will help or not, but heres the electromagnetic spectrum. when you use a radio or microwave, thats possible through radiation. and it isnt harmful because it has very low energy. when you see any sort of color, thats also radiation. the higher the energy, the more dangerous the radiation. another interesting tidbit is that these waves also determine how easy colors are for our eyes to see. for example, red is the easiest for us to see, and purple is the hardest.
so radiation is basically any kind of energy that travels through waves. not all radiation is bad. for example, light from a lightbulb is a form of radiation. wifi is a form of radiation. heat from a fire is radiation. the difference between this type of radiation and the radiation that everyone is warned about is the amount of energy. radiation that has low levels of energy isnt harmful in the way that high energy radiation is.
this type of radiation is the high energy wavelengths given off through xrays, gamma rays, and other sources like particles that radioactive materials give off. the problem with this radiation is that it has SO MUCH energy that it destabilizes atoms and interferes with the electrons. basically in the whole universe, electrons are pretty much of the utmost importance over everything else. electrons determine EVERYTHING about EVERYTHING. physics, chemistry, biology, etc
now when it comes to us as humans, our worry about radiation is it being a biological concern. high energy radiation can damage the electrical bonds in your cells, which hold together your entire body. when the atoms in your body become destabilized, chemical reactions can go wrong, and MOST IMPORTANTLY: structures can lose shape.
so our DNA is the genetic code which tells our body how to live. dna is made up of proteins, which are extremely specifically shaped to determind what each protein codes for in your dna. when your dna is damaged, it can create codes for cells to do things improperly. one example of this would be uncontrollable cell division, also known as cancer
now we didn’t necessarily “invent” xrays, they always existed. an xray is just another type of wavelength. just as visible light is. so for example, when you see the color red, you see that because of its wavelength. you could almost think of xrays as a “color” we cant see. the xray machine IS able to see these wavelengths, which is where we get actual xray photographs from
we dont visually NOTICE how easy/hard it is for our eyes to see it, but a way to conceptualize it is through blue light glasses. colors on the blue-violet end of the spectrum strain our eyes more, so these glasses are designed to reduce the amount of that light which reaches our eyes. beyond the blue-violet end of the electromagnetic spectrum is xrays. xrays are outside of the visible light spectrum, so even though they exists, we physically cannot see them through the naked eye
