The mechanism through which ionizing radiations halt cell division. Concept introduction: Ionizing radiations are those that ionize atoms or molecules by liberating electrons from their shell with the energy they discharge. Ionizing radiations consist of electromagnetic (EM) waves at the high end of the EM spectrum, atoms, ions, and subatomic particles moving at high velocity. Examples of ionizing radiations include γ-rays, X-rays, and UV rays of high end EM spectra. Specialized instruments are used to measure the levels of ionizing radiations, as they cause hazardous effects on the cells by damaging the DNA thereby cell death.
