Ionization
Radiation destroys cancer cells by inducing a process called treatment planning. Treatment planning is essential, because radiation can damage normal cells as well as cancer cells. Radiation therapy uses high-energy radiation to kill cancer cells by damaging their DNA.
A molecule with three oxygen atoms is called ozone (O3). Ozone is a naturally occurring gas in the Earth's atmosphere and plays a crucial role in absorbing ultraviolet radiation from the sun.
Radioactive elements are atoms that are unstable and undergo a process called radioactive decay, where they release energy in the form of radiation. This radiation can take various forms such as alpha particles, beta particles, and gamma rays, and can be harmful to living organisms if exposure occurs.
two or more atoms put together is called a molecule.
Ionizing radiation causes some of the atoms it strikes to be ionized. There are several different types: alpha particles, beta particles, neutrons, gamma rays, x-rays, and ultraviolet light. Non-ionizing radiation, which does not ionize atoms, includes visible light, infrared light, radio waves, and so on.To understand the biological effects of radiation we must first understand the difference between ionizing radiation and non-ionizing radiation. In general, two things can happen when radiation is absorbed by matter: excitation or ionization.Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.Because living tissue is 70-90% water by weight, the dividing line between radiation that excites electrons and radiation that forms ions is often assumed to be equal to the ionization of water: 1216 kJ/mol. Radiation that carries less energy can only excite the water molecule. It is therefore called non-ionizing radiation. Radiation that carries more energy than 1216 kJ/mol can remove an electron from a water molecule, and is therefore called ionizing radiation.Related links are provided below.
When chlorofluorocarbons (CFCs) are exposed to ultraviolet radiation in the stratosphere, they release chlorine atoms. These chlorine atoms react with ozone (O3) molecules, breaking them apart and leading to the depletion of the ozone layer.

nucleus, of course. that's why its called nuclear.
How do radiations produce heat?
The energy is called nuclear radiation, high energy particles and rays that are emitted by the nuclei of some atoms.
The ultraviolet radiation from the sun creates and destroys ozone naturally. It happens due to the high frequency of these waves.
Ionizing radiation
Ultraviolet radiation can rip electrons off the atoms to produce free radicals. However radiations of higher frequency can also have the same effect. The higher the energy of the photon of the electromagnetic wave, the easier it is for the photon to knock off electrons from an atom.
Radiation can interact with both atoms and molecules, but it does not necessarily need them to work. Radiation can propagate through a vacuum, such as in space, where there are very few atoms or molecules. However, when in contact with matter, radiation can cause ionization or excitation in atoms and molecules.
Some atoms are unstable and decay over a time period. The decaying is called radioactivity. Generally speaking, radiation decay of an atom usually (often) involves beta radiation (electrons), gamma radiation (very high energy light), and alpha radiation (helium nucleus). Atoms are identified by the number of protons (a one-proton atom is called a hydrogen atom, even if it has one or more neutrons).
