Arne Gundersen discusses criticality at Fukushima Daiichi Reactor 1.

Mr. Gundersen tells us today that there is evidence reactor 1 is experiencing moments of "inadvertent criticality", that is, the chain reaction may be spontaneously igniting from time to time. If this is so, deadly neutrons are being given off at those times. (The so-called neutron beam as noted here a few days ago.)
The workers at the site will not be aware of this because their dosimeters do not measure neutrons.

But wait. Dosimeters? We don't need no stinking dosimeters!
On Friday Japan's Nuclear Regulatory Agency reprimanded TEPCO for sending workers into the plant without dosimeters.
