Results from radiochemical analyses of small rodent whole bodies collected from breccia pipe uranium mines and reference locations in the Grand Canyon watershed.

These data are comprised of measurements of gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th, Ra-226) in small rodent...本数据集涵盖小型啮齿动物（small rodent）体内总α放射性活度（gross alpha activity）、总β放射性活度（gross beta activity）以及放射性核素活度（radionuclide activities，包含铀同位素（isotopic U）、钍同位素（isotopic Th）与镭-226（Ra-226））的测量数据……
