Their penetration powers are so great that “a neutrino has to pass through many ‘light years’ of matter to have a 50-50 chance of interacting" with the nucleus of some atom, according to “The New Quantum Universe” by Tony Hey and Patrick Walters. They are waveforms, as are light rays, microwaves, and radio waves. Question: 1- Which Type Of Radiation Is The Most Penetrating? Examples of this kind of radiation are radio waves, visible light and microwaves.Ionizing radiation has so much energy it can knock electrons out of atoms, a process known as ionization. Which type of radioactive decay produces radiation that can be stopped by a sheet of paper? gamma. The heavy, highly charged alpha particles are stopped by a piece of paper (or the skin). They are very penetrating needing a very dense material to stop them and carry high energy (they have very high frequency): 1437 views 5. These two types of radiation, due to alpha and beta particles, only affect a very localised area along their short trajectories. They are both part of the electromagnetic spectrum. Geiger. They are very penetrating needing a very dense material to stop them and carry high energy (they have very high frequency): X-rays have very short wavelengths, so they can penetrate the soft tissues of the human body. Terrestrial sources, such as a nuclear reactor or an atom bomb, also produce radiant energy. C. Gamma radiation is the most penetrating radiation. Neutron radiation is also encountered in nuclear power plants and high-altitude flight and emitted from some industrial radioactive sources. New answers. When comparing the most common forms of ionizing radiation (alpha, beta, and gamma), alpha particles have the greatest mass. They are not very penetrating. The most penetrating radiation is gamma radiation. Play this game to review Other. They are normally produced from the breaking of nuclei of atoms. Why is there a difference in the penetrating ability of the three basic radiation types? Electromagnetic radiation with shorter wavelengths penetrates materials most effectively. Gamma Rays are the most penetrative. It travels great distances through air (500 meters). All the stars, including the sun, emit radiation. 1 Answer/Comment. It is a form of ionizing radiation. The Electromagnetic Spectrum. However, alpha particles can be stopped by our skin, or even a thick sheet of paper. Thus, gamma rays is the most penetrating and can pass through several layers of concrete shielding. An alpha particle consists of two protons and two neutrons. A. Radiation Emissions.
