Radiation in the environment

Radiation in the environment

Radiation can be classified as non-ionizing and ionizing .

Non-ionizing radiation includes the static, low frequency and radiofrequency parts of the electromagnetic spectrum, as shown, where ionizing and non-ionizing radiation are separated by the visible light .

The non-ionizing radiation is to be found in industry, medicine, communications, research, commerce and private homes. Actually, exposure to radiation from man made emitters far exceeds that from natural sources, such as sun, stars and thunder storms.
