#' Quick table of Radionuclide Data from the RadData package

#' @family radionuclides

#' @description Access a quick summary of radionuclide data. This is for convenience only and does not replace a more comprehensive view as is available in the Radiological Toolbox <doi:10.2172/1201298>

#' @param RN_select identify the radionuclide of interest in the format "Es-254m"
