Activity 2: Ionizing Radiation A scientific journal article stated… When visible light or electromagnetic radiation with relatively long wavelengths is absorbed by matter, it is usually converted into thermal energy (heat). Shorter wavelengths, however, can ionize atoms and cause damage to living cells and its genetic material. This damage can cause the cell to die or may cause harmful mutations in the DNA. The article also shared this image of the EM spectrum showing the range of the spectrum that is considered ionizing radiation.
