write a short note on radaton
Answers
Answer:
1 There is a wide range of electromagnetic radiation in nature. Visible light is one example.
2 Radiation with the highest energy includes forms like ultraviolet radiation, x-rays, and gamma rays.
3 Radioactive atoms have unstable blends of protons and neutrons.
4 Radioactivity is the spontaneous release of energy from an unstable atom to get to a more stable state.
5 lonizing Radiation is the energy that comes out of a radioactive atom.
6 Radioactive isotopes are radioactive atoms of the same element that have different numbers of neutrons.X-rays and gamma rays have so much energy that when they interact with atoms, they can remove electrons and cause the atom to become ionized.
7 Radioactive atoms can give off four types of ionizing radiation: alpha particles, beta particles, gamma rays, and neutrons.
8 Each type of radiation has different properties that affect how we can detect it and how it can affect us.
9 Radioactive decay happens when an unstable atom gives off radiation and changes into a more stable atom of a different element.
10 The length of time it takes for half of the radioactive atoms in a group of radioactive isotopes to decay is called a half-life.
hope it helps
