This outer-shell electron is considered to be essentially free of the atom because its binding energy is so low, which is the case in high atomic number materials.\u003c/p\u003e\u003cp\u003eAdapted from\u0026nbsp;\"Basic Physics of Digital Radiography\" 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":621,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2748","nextQuestionPath":"/articles/compton-effect/questions/620","relatedArticles":[],"alsoUsedIn":[],"stem":"\u003cp\u003eWhich of the following is true in regards to Compton scattering?\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/621"}],"attemptsPercentages":[{"alternativeId":"3113","percentage":16},{"alternativeId":"3114","percentage":8},{"alternativeId":"3115","percentage":65},{"alternativeId":"3116","percentage":11}],"promptToLogin":false,"questionManager":false,"articleId":"compton-effect"}
