There are two types of radiation: rays and high-speed particles. There are atoms in everything. The nucleus of an atom includes protons and neutrons, whereas the atom's outer shell contains other particles known as electrons.
The electrons have a negative charge, whereas the nucleus has a positive charge. The atom's internal forces maintain a stable equilibrium by eliminating excess atomic energy (radioactivity). As a result, unstable nuclei may spontaneously produce specific energy, which we call radiation.
Radiation comes in a variety of forms. Every day, for example, we use light, heat, and microwaves. To view inside our bodies, physicians employ X-Rays. Our favorite shows may be heard and seen on the radio and television. Radiation comes in all shapes and sizes.
Since the beginning of time, radiation has also been a part of our surroundings. Cosmic radiation from the sun and stars is like a steady rain that falls on the earth. There is also a source of terrestrial radiation that comes from the earth itself.
