#Fukushima I Nuke Plant: Radioactive Materials in Reactor 1's Trench

From TEPCO's latest update on the plant status as of 10:00PM JST, March 30, 2011(Japanese; English document contains errors in the names):

On March 29th, we detected niobium, technetium, ruthenium, silver, tellurium, iodine, cesium, and lanthanum in the water collected at the trench of unit 1

Some exotic names. The Reactor 1's trench was supposed to have been filled with tsunami water.
