Look, Santa Claus came early this year, and he dropped off this package for us today! Our Geiger counter quickly used up most of its scale when brought near it!
In all seriousness though, it's a cobalt-57 source from Obninsk, Russia, a gamma emitter that we use für Mössbauer spectroscopy, which is also the topic of my master thesis.
And in other awesome news, today was my last day of work for this year, and we'll be departing towards Switzerland for our yearly ski trip after Christmas. Yay!
no, we most load and unload packages from the planes and the cans. Granted several people have bad habits of holding them to close to personal body parts.
