1984 J. R. Tighe & D. R. Davies Pathol. (ed. 4) xi. 89 The ionizing power of any radioactive source is measured in terms of its effect on a standard quantity of air.

2005 V. A. Goldade et al. Plastics Corrosion Inhibition i. 15 The cathodic reaction of oxygen under the coating is retarded or the process of metal ionizing is accelerated.

1902 Electr. World & Engineer 13 Sept. 424/2 The proximity of a metal has the effect of reducing the ‘ionizing potential’ of a molecule to an extent varying from one metal to another.

1924 S. Dushman in H. S. Taylor Treat. Physical Chem. II. xvi. 1110 This accounts for the production of arcs in gases at voltages below the ionizing potential.

2007 M. Windelspecht Genetics 101 119 Although alpha particles have a high ionizing potential, they will not penetrate very far into the tissue and thus are readily stopped by the skin.

1896 Jrnl. Amer. Chem. Soc. 18 287 The latter class of solvents are to a certain extent also ionizing, since when saturated with hydrochloric acid they act as conductors.

1935 Discovery Mar. 76/2 It was clear that the sun is the ionising agent.

1981 P. Sykes Guidebk. to Mechanism in Org. Chem. (ed. 5) viii. 237 It occurs only in powerful ionising solvents.

2003 New Scientist 31 May 16/4 Workers at a nuclear reactor exposed to high levels of sparsely ionising gamma rays and mutating chemicals had very few intrachromosomal changes.

1901 Nature 11 Apr. 578/1 The ionisation in a closed vessel is the same... It appears, therefore, not to be due to the action of ionising radiation which has traversed our atmosphere.
