plutonium Fukushima and DU-weapons

What about the Du-weapons? Are they also a reason for increasing radioactivity everywhere? Are they also with plutonium? When you cannot mesure plutonium with a Geiger counter, how will you mesure the contamination? Are there daily mesurements, more mesuring stations or only one university, where you can mesure in experiment? Which university does these tests best??? Are they official?
