Ionising em waves
Web12 jan. 2016 · Ionising radiation The most energetic radiation, namely gamma rays, x-rays and a certain part of ultraviolet light, are dangerous for our bodies because they are able to knock electrons out of atoms (ionisation) as a result of their high energy. These forms of radiation are called ionising. Non-ionising radiation Web8 mrt. 2024 · Ionising radiation can remove an electron from an atom or molecule. These atoms or molecules are then said to be ionised and are unstable. Gamma Rays, X rays and some types of UV radiation are ionising. Ionising radiation can lead to changes in the DNA of a cell. Electromagnetic Spectrum Facts We can only see visible light.
