Alpha radiation.
Alpha radiation is the least penetrating type of radiation. It consists of helium nuclei and has low penetration power, being stopped by skin or even a sheet of paper.
Alpha radiation is the least ionizing type of nuclear radiation. It consists of positively charged alpha particles, which have low penetrating power and are easily stopped by a sheet of paper or clothing.
The three types of radiation given off by radioactive substances are alpha particles, beta particles, and gamma rays. Alpha particles are the least penetrating, beta particles are more penetrating than alpha particles, and gamma rays are the most penetrating and dangerous type of radiation.
Gamma Ray
The gamma radiation is extremely penetrant.
Alpha radiation is the least penetrating type of radiation and is easily absorbed by a few centimeters of air, a piece of paper, or even human skin.
Gamma radiation
Alpha radiation has the least ability to penetrate matter. It consists of particles that are relatively large and heavy, which makes them easier to block. They can be stopped by a piece of paper or human skin.
Generally gamma radiation is the most penetrating one, but it is also least ionising. I don't quite understand what you mean by saying "Nuclide" radiation. Nuclides are generally isotopes, not radiation. Nuclides (isotopes) don't have to be radioactive, but the isotopes that lie outside the curve of stability (function of the number of proton and the number of neutrons in a particular nucleus) are unstable and do decay (are radioactive)
Gamma radiation is considered the most deadly type of radiation as it is highly penetrating and can easily damage tissues and cells in the body. This type of radiation is emitted during nuclear reactions and explosions.
Cobalt-60 produces gamma radiation, which is a type of electromagnetic radiation that is highly penetrating and can be used for various applications such as radiation therapy in cancer treatment and industrial radiography.
Gamma radiation has the highest penetrating ability among alpha, beta, and gamma radiation. This is because gamma rays have the shortest wavelength and highest frequency, allowing them to penetrate most materials easily.
