Includes easy to follow powerpoint, worksheet activities and answers written to make it easy for students to follow and self assess. This excited nucleus may make a transition to a lower energy state by emitting electromagnetic radiation. The beta particles are a form of ionizing radiation also known as beta rays. It can be stopped by a piece of paper and posses no threat to any human tissue. But gamma being just a radiation/non-massive photon penetrates with highest power radiations. In actual plant situations, the mixture of beta-emitting radionuclides and the ratio of beta- to gamma-radiation intensity may change with time. Beta radiation from linac accelerators is far more energetic and penetrating than natural beta radiation. The ability of radiation to damage molecules is analyzed in terms of what is called ionizing power. Gamma. When a radiation particle interacts with atoms, the interaction can cause the atom to lose electrons and thus become ionized. | EduRev Railways Question is disucussed on EduRev Study Group by … Explanation of Solution. Beta Radiation. Beta particles are high-energy, high-speed electrons or positrons emitted by certain fission fragments or by certain primordial radioactive nuclei such as potassium-40. There are three types of nuclear radiation: alpha; beta; gamma; Alpha radiation. Without additional energy input, these characteristics make alpha particles less penetrating than beta particles and gamma rays. ANS: 4 16.

Gamma particles have the highest penetrating power among the given types of radiation. ... A beta particle maybe spontaneously emitted from. The type of radiation which has the least penetrating power is 1) gamma rays; 2) X rays; 3) beta particles; 4) alpha particles. Gamma rays are highly energetic waves and are poor at ionising other atoms or molecules. Beta-radiation fields in and around a commercial nuclear power facility are extremely difficult to characterize. Beta radiation is strong, but still not lethal. The more radiation passes through a matter, the greater is its penetration power. Beta radiation is quite penetrating into the body, but not as much as gamma rays. Gamma rays are the most penetrating of the radiations. Can you explain this answer? Beta radiation consist of free electrons or positrons at relativistic speeds.These particles are known as the beta particles. Beta-plus (β +) radiation is the emission of positrons, which are the antimatter form of electrons. Betas have only about 1/8000 of the mass of an alpha paticle and only half of the charge. Animation showing the penetrating power of the three different types of radiation. Beta radiation is more penetrating than alpha radiation.
