nuclear radiation

Radiation and particles coming from the nuclei of radioactive atoms during radioactive decay and nuclear reactions. Alpha particles are the nuclei of helium atoms, beta particles are high-speed electrons, X-rays and gamma rays are electromagnetic radiations of wavelength progressively shorter than visible light. Nuclear radiations differ in penetration, beta particles being least penetrative and the gamma rays most. Ionizing radiations can dislodge linking electrons from molecules, such as those of DNA, and cause damaging changes. In general, radiations are most destructive to cells most rapidly dividing.
