radiation: Tracks of rays can hardly be seen. The tracks are due to some other particles produced by a complicated mechanism involving rays. (Photo credit: Lord Blackett’s Estate) 4 Penetrating power How far radiation can penetrate into a material relates to its ionizing power...
What is alpha (α) radiation? Description 2 neutrons, 2 protons Note:– An alpha particle is the same as a helium nucleus Electric charge +2 Relative atomic mass 4 Penetrating power Stopped by paper or a few centimetres of air Ionizing effect Strongly ionizing Effect of magnetic/ electric fie...
either an electron, β–, or a positron, β+, changes the atomic number of the nucleus without affecting its mass number. The total rest mass of the daughter nucleus and the nuclear radiation released in a beta disintegration, mDaughter+ mRadiation, is always less t...
Radiation can occur in the form of electromagnetic waves (e.g., visible light, infrared, x-rays, gamma rays), or particles (alpha, beta). Comparison of the penetrating power of alpha and beta particles, and gamma rays, reveals that beta particles are more penetrating than alpha...
Beta particles have greater speed and penetrating power than alpha particles. ♦ The process by which a neutron becomes a proton and emits an electron is called beta decay. Beta decay results in the atomic number of an element being increased by one and its mass number staying the same. ...

of meters in the air. This distance depends on the energy of the particle. Typically, beta particles come under ionizing radiation, and it is comparatively more ionizing than gamma rays. However, it is less ionizing than alpha particles. Higher the ionizing effect, lower the power of ...
is made use of in smoke detectors. It is also used in many other applications such as in generators used in space probe experiments and also as pacemakers used for treatment of heart problems. It is easier to safeguard oneself against alpha radiation than beta radiation which is more dangerous...
