Effects of exposure to X-ray radiation measured as the comparison of nest volume at each time interval between nests excavated under the 0P experimental treatment (grey) and control treatment nests (black). The 0P treatment consisted of six individual replicates excavated by different donor colonies that were all scanned at each of the time intervals while the control treatment consisted of six replicates of seven nests excavated by ants from the same donor colonies where each nest was only scanned once at one of the corresponding time intervals.
