Electromagnetic radiation is a very broad concept. If you look up 'electromagnetic spectrum', you will see that it is radio waves, infrared, visible light, ultraviolet, x-rays, gammas rays, etc. So, what are the uses?

Well radio waves are used for radios and other wireless communication like Wi-fi. This is pretty simple to figure out the uses and dangers (if any).

Infrared lights are used in many areas for different things. Your TV remote uses infrared. It's used for thermal imaging. It's used the sciences all the time. It's not particularly harmful either.

And visible light? I don't have to go into detail for this (if I should, you have a bigger problem).

UV light can be harmful, but many new technologies are making use of it. For the most part, it can be damaging to eyes and skin for long exposures and intense sources.

Microwaves. Microwaves are electromagnetic radiation too. Obviously, we are familiar with the conveniences of a household microwaves. These can be harmful because they are absorbed by water easily.

X-Rays and Gamma rays are used in medical sciences a lot as well as cutting edge physics experiments, particularly with astrophysics. These types of electromagnetic radiation are very high energy and can disrupt chemical bonds. This is mostly of concern with us because it can damage DNA and cause mutations and other carcinogenic effects.

There are both pros and cons for the effect of EM radiations .The EM radiations like micro waves,radio waves,x-rays,gamma rays have a very good and great approach in the field of medicine and our daily needs like micro wave ovens-which use micro waves;cell phones-which use radio waves;cancer treatment-which use gamma rays and so on .

But so as every situation and problem has an another side there are also some negative effects of the EM radiation on the human habitat.For example lets deal with the UV rays which are the harmful rays and the effect is being suffered by us in the present environment.And also many more but before the situation turns worse lets hope we shall not be endangered.................

There are a number of ways.

A microwave oven operates at 2.45GHz as the resulting wavelength is comparable to the size of a water molecule. Therefore, it is able to rapidly rotate the molecule (due to water's ionised polarity), creating "friction" between molecules, heating up the water. This also happens to fats, sugars etc.

So aiming a EM source at yourself at that frequency will cause burning.

X-rays and gamma rays have significantly higher frequencies which enable them to penetrate deep into your body, hence the use of X-rays in medicine. These have the potential to cause various forms of damage (through what mechanism?).

High exposure to X-rays and gamma rays has been linked to high incidences of cancer.

It has been speculated (loosely) that the frequencies of radiation emitted by mains-frequency power can also increase the risk of cancer. There are claims that children living under power lines are at a greater risk of cancer, although the intensity of EM radiation they will receive from these lines is, due to the inverse square law of divergence from the line, orders of magnitude smaller than they will receive from power outlets in their' rooms. Therefore even if the link between mains power and cancer is correct, the power lines have nothing to do with it.

A number of studies have "conclusively proved" and"conclusively disproved" the theory that use of mobile phones (which use the microwave spectrum at roughly 300MHz to 3GHz) increases the risk of... again... cancer. The strongest evidence so far has demonstrated that of patients with particular types of brain tumors, the tumor is slightly more likely to be on the side of the head where the patient often uses a mobile phone than on the other side.

However, the new "4G" frequency range for mobile communications includes the 2.54GHz typical "heating" frequency.

Radioactive radiation, such as X-rays and gamma rays, is dangerous and can harm, and even kill living things.

How do infrared rays affect your environment?

Infrared rays are a part of the electromagnetic spectrum which is the range of electromagnetic radiation, so if put in the hands of the human industry with weaponising and telescopes and the DVD's it is bad for the environment and is what is effecting the changes of climate through its radiational effect. Infrared rays affect the environment by giving of radiation, causing cancer etc.
