In addition to the digest version of the video of January 19 operation to look inside the Containment Vessel of Reactor 2 with the Olympus endoscope, TEPCO has released the longer version in 4 separate videos.
(It is very trippy.)
Total 34 workers manipulated the endoscope just outside the Containment Vessel. Radiation in Reactor 2 is tame compared to Reactor 1 or Reactor 3, but the radiation level was still over 20 millisieverts/hour.
