    get you more than robots. Sure you have to get out of the cab sometimes, it's better than nothing. Look at the photos, you'll see guys doing nothing obvious but waiting, standing right next to the reactors.

    98% effective shields can be knocked up at local body shops. No rocket science involved.  As long as the plates of lead overlap and you have a tank of compressed air to maintain positive pressure in the cab you're good.

    Any construction foreman can figure this stuff. This does not require advanced degrees in physics or math.It does not require special certification in reactor engineering.

    It will look like Mad Max. Which is a problem only if your PR team is telling you to never fucking admit it's an emergency.

    Since the Japanese auto industry is running at halfspeed anyway, tell Toyota, Mitsubishi, Koboda you need more professional looking gear by next week.

    There is apparently not one person on this emergency who has a clue how to take charge in an emergency.

    •  Amount of lead needed (6+ / 0-)

      to cover a cab of a truck would possibly collapse it.  When placing lead shielding on piping it needs engineering approval.

      Special "beefed up"  scaffolds are often built around a "hot" component. Lead blankets are then hung from these scaffolds, which need engineering approval.

      Positive pressure not needed, as worker / driver would be wearing respirator.

    •  They are already using a lead-shielded vehicle (6+ / 0-)

      and remotely operated power shovels and bulldozers. The link has a video of the equipment. To the best of my knowledge Japanese companies don't have any experience with shielded equipment. All the stuff I've seen in press coverage has been American, French and German.

      NHK WORLD English

      Tokyo Electric Power Company has begun using unmanned heavy equipment to remove radioactive rubble at the tsunami-hit Fukushima Daiichi nuclear plant.
      The utility started using remote-controlled power shovels and bulldozers to remove the rubble on Sunday afternoon.

      Operators are using cameras attached to the equipment as well as 6 fixed cameras at the site to carry out the work from hundreds of meters away.

      A lead-covered mobile operating room will be used to remove debris from places that cannot be reached by radio waves.
