What type of radiation is emitted in the decay?
Radioactive decay is the emission of energy in the form of ionizing radiation. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes.. The ionizing radiation that is emitted can include alpha particles.

Which of the following is not emitted during radioactive decay?
During this decay there is emission of gamma particles from the nucleus. After observing the options, we can say that protons are neither emitted by the decay of radioactive substances. Hence, the correct answer is option (A) i.e. a radioactive substance does not emit protons.
Why are gamma rays emitted?
When an unstable atomic nucleus decays into a more stable nucleus (see radioactivity), the “daughter” nucleus is sometimes produced in an excited state. The subsequent relaxation of the daughter nucleus to a lower-energy state results in the emission of a gamma-ray photon.
What is emitted in beta decay?
In electron emission, also called negative beta decay (symbolized β−-decay), an unstable nucleus emits an energetic electron (of relatively small mass) and an antineutrino (with little or possibly no rest mass), and a neutron in the nucleus becomes a proton that remains in the product nucleus. …
What does neon decay into?
Nucleogenic neon Most of these alpha particles come to rest as helium-4. These decay chains are the basis for the well-known (U-Th)/He, (U-Th)/Pb, and U-series disequilibrium dating systems. A small proportion of the alpha particles react with other elements like oxygen and fluorine.
Which of the following can be emitted by radioactive substances during their decay?
Radioactive substances are atoms that decay naturally. They can give off alpha particles, beta particles and gamma radiation.
What is not emitted by radioactive substances?
The first decay is alpha decay. During this decay there is release of alpha particles from the nucleus. After observing the options, we can say that protons are neither emitted by the decay of radioactive substances. Hence, the correct answer is option (A) i.e. a radioactive substance does not emit protons.
What types of radiation are emitted during nuclear reactions?
In nuclear reactions, the protons and neutrons are rearranged in the nucleus of the atom to form new elements. Radioactive substances give off three types of radiation; alpha particles, beta particles and gamma rays.
