11. One type of treatment for cancer is radiotherapy. Cancer cells die if they absorb a high enough radiation dose. The diagram shows how much relative radiation dose is absorbed when photon radiation and proton radiation respectively reach different depths in tissue. Relative absorbed dose (%) 100 80 60 40 20 10 photon radiation proton radiation 15 5 10 depth in tissue (cm) type of radiation best suited for treating a tumor that is 15 cm deep?

Radioactive decay
The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. This periodic table's elements come in a variety of shapes and sizes. Several of these kinds are stable like nitrogen-14, hydrogen-2, and potassium-40, whereas others are not like uranium-238. In nature, one of the most stable phases of an element is usually the most prevalent. Every element, meanwhile, has an unstable state. Unstable variants are radioactive and release ionizing radiation. Certain elements, including uranium, have no stable forms and are constantly radioactive. Radionuclides are elements that release ionizing radiation.
Artificial Radioactivity
The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
