yes the radiation has increased in unit 1 but its not spewing out.
if it was spewing out you would see a increase in reactors two and three
you can get widely varying reading just from a change of the amount of water on the floor in the room that the meter is in..
if i remember unit one is still being cooled by the water spray truck.
the real information would be a graph of temperature and radiation.
if they are both going up you have a real problem. if its just the radiation its not a real problem.
any place inside the three reactor buildings in no mans land.
the only thing that will be entering except for very short term trips is robots.
robots will have to removed the debris from damaged reactor building.
the reactors and fuel pools will have to be the fuel removed by robots.
then the robots will have to clean the building. to the lowest radiation levels possible
This was how they cleaned up three mile island.
Its my understanding that in the US and japan they are already building over 60 radiation hardened robots just to clean up these reactors.
