april 1940: UM zendt nog 3 ton uranium naar Joliot

The first, with five tons of uranium oxide, the second with fifty tons, were to be supplied by Union Minière. A first consignment of five tons was sent to Paris immediately in June 1939 and later, in April 1940, three more tons were sent before the German invasion.
