In quantitative terms, equivalent dose is less fundamental than\u0026nbsp;absorbed dose, but it is more biologically significant. Equivalent dose has SI units of sieverts but rem (roentgen equivalent in man) is used commonly (1SV = 100REM)\u003c/p\u003e","id":496,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/743","nextQuestionPath":null,"relatedArticles":[],"alsoUsedIn":[],"stem":"\u003cp\u003eWhen quantifying levels of radiation, the dose equivalent is…\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/496"}],"attemptsPercentages":[{"alternativeId":"2488","percentage":26},{"alternativeId":"2486","percentage":5},{"alternativeId":"2485","percentage":26},{"alternativeId":"2487","percentage":43}],"promptToLogin":false,"questionManager":false,"articleId":"equivalent-dose"}
