The maximum x-ray energy is equivalent to the maximum electron energy. The average x-ray energy is 1/2 to 1/3 of the maximum x-ray energy (in this case 26-27keV).\u003c/p\u003e\u003cp\u003eAdapted from\u0026nbsp;\u003ca href=\"https://en.wikibooks.org/wiki/Basic_Physics_of_Digital_Radiography\"\u003eBasic Physics of Digital Radiography\u003c/a\u003e\u0026nbsp;by\u0026nbsp;Kieran Maher,\u0026nbsp;with author's permission (License:\u0026nbsp;\u003ca href=\"https://creativecommons.org/licenses/by-sa/3.0/\"\u003eCreative Commons\u0026nbsp;BY-SA 3.0\u003c/a\u003e).\u003c/p\u003e","id":632,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2737","nextQuestionPath":null,"relatedArticles":[{"id":25429,"title":"Characteristic radiation","link":"/articles/characteristic-radiation?lang=us"}],"alsoUsedIn":[],"stem":"\u003cp\u003eElectrons striking the tungsten anode of an x-ray tube with 80 keV energy can produce...\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/632"}],"attemptsPercentages":[{"alternativeId":"3168","percentage":4},{"alternativeId":"3169","percentage":2},{"alternativeId":"3167","percentage":12},{"alternativeId":"3165","percentage":67},{"alternativeId":"3166","percentage":12},{"alternativeId":"3217","percentage":2}],"promptToLogin":false,"questionManager":false,"articleId":"bremsstrahlung-radiation"}
