I still think it would be easy to compare growth rates of the offspring of captured mice to those found nearby. It should be slower.

Breeding for radiation tolerance?
The Economist reports that a team compared birds found in a radiation area (0.5-35 microsieverts/hour) near Fukushima and those found in similar areas near Chernobyl. The drop in bird numbers was twice as large at Fukushima. While they admit that this might be because different isotopes could, by being absorbed into the body differently, deliver different doses, they attribute this to birds having adapted to the radiation environment at Chernobyl. Not perfectly--there's still a decrease in number relative to low-radiation areas.
