| Abstract | ICRU Report 90 on Key Data for Ionizing‐Radiation Dosimetry: Measurement Standards and Applications (2014) has reaffirmed the recommended value of the mean energy required to create an ion pair in air, Wₐᵢᵣ, to be 33.97(12) eV. The report also indicates that this “constant” of radiation dosimetry is energy independent above 10 keV, since there is no theoretical or experimental evidence to the contrary. The goal of this investigation is to obtain additional experimental determinations of Wₐᵢᵣ in high energy beams and thus to verify the suggested energy independence. |
