Bleak conditions persist more than one year after the start of the nuclear accident. Take a look at the photos released by TEPCO on April 5, 2012 of the latest leak. Kanaflex hoses bundled and wrapped with black insulation material.
I do not know if the insulation material was ripped by the workers to find the leak, or it had been ripped before.
From TEPCO's "Photos for Press" (4/5/2012):
The water was rich in beta nuclides according to TEPCO, who released the data without specifying the locations where they took the samples ("upstream dam No.1, downstream dams No.2 and 3..."). The unit is per cubic centimeter, and no breakdown of which beta nuclides they detected.
