#Fukushima I Nuke Plant: "Warrior" Robot Vacuumed Reactor 3 Floor, Radiation Still Very High

Yomiuri Shinbun reports that the "Warrior" robot from iRobot went inside the reactor building for the Reactor 3 to vacuum the highly radioactive (or so TEPCO thought) sands accumulated on the floor right off the truck entrance.

It completed the task, braving the high radiation (more than 100 millisieverts/hour in some spots) on July 1. It took the robot 5 hours to collect dust and sand in 3 200-liter containers.

Unfortunately, the radiation level in the area only went down by 10 to 20 millisieverts/hour, and TEPCO is considering laying down the steel plates on the floor to see if they block the radiation.
