Neutron beam observed 13 times
Tokyo Electric Power Co. said Wednesday it has observed a neutron beam, a kind of radioactive ray, 13 times on the premises of its crippled Fukushima No. 1 nuclear plant.
Tepco said the neutron beam measured about 1.5 km southwest of the plant's Nos. 1 and 2 reactors over three days from March 13 and is equivalent to 0.01 to 0.02 microsieverts per hour. This is not a dangerous level of radiation, it added.
I suggest readers completely disregard the "not dangerous level fo radiation" comment.
I'm following the discussion of this "beam" at zerohedge. Commentators there suggest the account makes little "sense" from a technical perspective but does suggest that some level of criticality--or nuclear fission--has been achieved and is not contained at the plant.
