21. The electrons travel through the gauge and ionize gas molecules around them. 22. Recoiling nuclei can ionize and excite further atoms through collisions. 23. A few completely ionized nuclei of heavier elements are present. 24. Nuclear medicine imaging equipment and scintillation due to ionizing radiation. 25. Such swept crystals have a very low response to steady ionizing radiation. 26. At such conditions, the atoms are ionized and make a plasma. 27. This allows one to multiply ionize an atom with a single photon. 28. The electron is ionized through multiphoton coupling with the continuum. 29. Cataracts have been associated with ionizing radiation such as X-rays. 30. Alpha particles are a highly ionizing form of particle radiation.
