nuclear radiation meaning

Both alpha and beta particles have an electric charge and mass, and thus are quite likely to interact with other atoms in their path. Nuclear radiation definition, radiation in the form of elementary particles emitted by an atomic nucleus, as alpha rays or gamma rays, produced by decay of radioactive substances or by nuclear fission.

Nuclear radiation is the energy given off by all radioactive elements when they break down into more stable atoms. Our new online dictionaries for schools provide a safe and appropriate environment for children. Ionising radiation is produced from natural and artificial radioactive materials. Ionizing radiation which can damage living tissue is emitted as the unstable atoms (radionuclides) change ('decay') spontaneously to become different kinds of atoms. Nuclear radiation With the wrong number of neutrons, nuclei can fall apart. Examples of decay include alpha decay, beta decay, gamma decay, neutron release, and spontaneous fission. Nuclear radiation refers to the particles and photons emitted during reactions that involve the nucleus of an atom. The least dangerous type of radiation. What are synonyms for nuclear radiation? To identify the stability of an isotope it is needed to find the ratio of neutrons to protons. As the level of radiation rises, radiation can cause hair loss, loss of white blood cells (making casualties of radiation even more susceptible to infections), and can result in death. ­Nuclear radiation can be both extremely beneficial and extremely dangerous.
