[Fuel in the upper floor ?] Radiation level higher near the equipment on the ceiling

On 6/17/2013, Tepco investigated the 1st floor of reactor2.

(cf, [Mystery] Upper parts are more contaminated on the first floor of reactor2 [URL])

In this investigation, it was confirmed that the higher it is, the higher the radiation level is.

In the west part of the 1st floor, Tepco had the robot measure radiation level at 17 locations.

The highest reading was 19 mSv/h at 4.3 m from the floor. The lowest reading was 6 mSv/h at 1.6 m from the floor.

The upper part of 1st floor is full of the pipes and ducts. They are more contaminated than the floor but the reason is not verified.
