Former Japan PM ‘hints’ of recriticality at Fukushima
— Found Chlorine-38 in Reactor No. 1 water tested at research
mass, Nature Magazine, Dec. 15, 2011:
than nine months after the nuclear-reactor disaster at Fukushima,
fundamental questions about what happened remain unanswered.
Without answers to these questions, Japan, and the rest of
the world, is in the dark on what went wrong, what must be
done now, and how to avoid similar accidents in future.
Comment in this week’s issue summarizes these concerns
(see page 313). For the Japanese public, one of the most troubling
things about the article should be the identity of its authors:
two ruling party politicians, including a former prime minister.
Surely they should be able to get some answers? [...]
the issue is not available online, but Yomiuri summarizes
Nationalize Fukushima N-plant, Yomiuri Shimbun,
Dec. 16, 2011 (Emphasis Added):

1. Criticizes Tokyo Electric Power Co., the operator of
the crippled plant, for disclosing only limited information
to Diet committees
2. Hints at the possibility of recriticality at the

also says that he and [Tomoyuki Taira, member of the House
of Representatives] obtained data on samples of contaminated
water TEPCO obtained from the basement of the plant’s
No. 1 reactor and asked an outside research institute to reanalyze
showed that radionuclide chlorine 38, one
of the isotopes released during recriticality, “was
indeed present,” he claims.
reported at one point that it found chlorine 38 in the sampled
water, but the utility later retracted that statement, saying
there was a mistake in the analysis.
More from Yomiuri
by bringing the Fukushima No. 1 nuclear power plant into government
hands can scientists thoroughly discover what caused the nuclear
crisis, former Prime Minister Yukio Hatoyama says in an article
published in the Dec. 15 issue of the British science journal
said the Fukushima plant “must be nationalized so that
information can be gathered openly.” [...]
is extremely rare for a major science journal to carry an
article written by a former prime minister as a cover story,
according to an official of Nature Japan.

that would constitute an exposure of 193 millisieverts.

background on the significance of this level, see my posts here
Diego has had much lower levels, according to radnet, than many
other areas of the country.
192 millisieverts would simply reflect external exposure and
would not include the contribution of internal emitters from
contaminated water or food and would not include the contamination
load each of us carries from a cumulative lifetime of exposure
to natural and artificial ionizing radiation.
need to wake up and start demanding that their federal and state
officials increasing air, food, and water monitoring and disclosure.

Radiation Increases and Why They Matter, majiasblog.blogspot.com.
post is not intended to imply that levels in the US are comparable
to those in Japan. Rather, the point is simply to reinforce
the truth that Fukushima is a global problem capable of impacting
lives many thousands of miles away.
is why we need global cooperation and transparency on Fukushima
said, now I turn to examine radiation in Phoenix and I address
why relatively low-levels matter.
Clyde Stagner on Phoenix Radiation:
Gross Beta 2007-2010 was .0143 pCi/L^3
Gross Beta Jan 3- Oct 2011 was O.O158 which is a 9.5% increase
to CPM is mathematical, but the increase will remain the same
increase is either from utility [Palo Verde] or Fukushima with
events occurring in Fukushima supporting the increase to the
CPM -the best Clyde"
here: And this 9.5% increase was before we had the big spikes
ranging upward to 850 CPM in November and December (30 to 60
highest reported level we had in March was 300 CPM. We had a
few spikes in May but the real increases were this fall.

Than Background Radiation, Potrblog team
1:00 pm sample swipe of the rain off the SUV returned a reading
of 7X background radiation. It appears that the La Nina weather
pattern is pushing the Southern Jetstream towards Saint Louis;
the result is reduced fallout from Fukushima.
the corium hit Fukushima ground water in August, Radon and meltdown
products have been moved towards North America via the Northern
Jetstream. Rains from the Northern Jetstream have dumped short
half life radiation with readings above 276 times greater than
background radiation (2.76 mR/hr) on Saint Louis; The very same
rains have also dumped long lasting radioactive fallout which
continues to be detectable. At least one of the rains has had
strong indications of the presence of Neptunium 239 (which quickly
decays to Plutonium 239). There have also been previous indications
of Iodine 133 / Xenon 133, however those detections have a greater
uncertainty than previously thought.
appears the La Nina weather pattern will be protective of the
Saint Louis area, and points South) through out the winter.
The primary Fallout risks will be from the encroachment of the
Northern Jetstream, and the resultant snow/ice."
So Cal Rain, by Michael Collins, enviroreporter.com
(For the radiation measurement update page, please link here)
already knew that the EPA considers anything at three times
background to be `significantly' above background, hence why
we make special note of when any media we test comes above background.
But what we didn’t know is that following readings actually
qualify as hazmat-level high for the California Highway Patrol.
rain reading came right off the coast earlier today:
SPOT CHECK SANTA MONICA RAIN: ~166 CPM sustained or 415% of
normal higher (Videotaped)
INTERIOR RADIATION STATION BACKGROUND: ~40 CPM^
to our friend and colleague over at Potrblog,
we found out that the CHP defines a hazmat incident as anything
three times background or higher, which then triggers certain
protocols by the agency as the fascinating following report
STATE REPORT- LINEN TRANSPORT TRUCK DETAINED AFTER SETTING
OFF RADIATION ALARM
following information was provided via email:
12/8/11 at 1430 PST, the Nevada Radiation Control Program
(NRCP) received a call from the Alternate Radiation Safety
Officer (ARSO) for Renown South Meadows Medical Center, that
a truck carrying linen had been detained by the California
Highway Patrol (CHP) at the Truckee inspection station after
setting off a radiation alarm. The ARSO explained that the
truck was not carrying any materials from the Nuclear Medicine
Department or decay room and she knew of no reason that it
would be radioactive. She provided the name and number for
the CHP at Truckee.
NRCP contacted the CHP and were told that they had surveyed
the truck with a Ludlum meter and measured .400 millirem per
hour (or 400 microR/hour) outside the trailer. The CHP said
that their protocols dictate that anything above three times
background is treated as a hazmat incident and must have proper
packaging and manifest. They had not run an identification
spectrum on the truck. They had no capability to unload a
trailer on site for further investigation. They were holding
the vehicle pending instructions from their departmental radiation
specialist and agreed to call [the NRCP] when they had a decision.
Aramark (linen service) representative confirmed that the
vehicle in question was a tractor trailer and was carrying
only linen from Renown.
approximately 1545 PST, the CHP called and indicated that
they had released the trailer with orders to return to Renown
Medical Center. They were unable to identify the radioisotope
present and the dose rate reading was now .100 millirem per
hour (100 micro R/hr).
NRCP Incident Response Supervisor arrived at Renown Medical
center at approximately 1645 PST, shortly after the truck,
and met with Renown staff. After conducting a radiation survey
on the outside of the truck, he determined the general location
of the high radiation and identified Technetium-99m (Tc-99m)
as a suspected isotope. Linens are transported in large plastic
bins, which were removed with a pallet jack, by the staff
at Renown. When the radioactive bin was identified, it was
segregated, a thorough survey was done and the radioisotope
was positively identified as Tc-99m. The bin was placed in
Renown’s decay room where it will remain for 2 to10
days until the Tc-99m decays.
most likely cause of this contamination was that a recently
treated patient soiled the sheets and the possibility of radioactive
contamination was not recognized by floor staff. Linens are
not routinely screened for radiation. Aramark recently began
transporting linens to Sacramento, rather than processing
locally, so they are now subject to inspection upon entering
California. The RCP will assist Renown with some procedure
changes that will minimize the chances of this happening in
rate readings were one order of magnitude lower than what
CHP reported. It is unknown why CHP was unable to obtain an
accurate identification of the isotope.
readings: RadEye – Background 6 uR/hr; at bin 48 uR/hr;
Ortec MicroDetective – Background 65 counts per second;
at bin 1800 counts per second; Renown 451P Ion Chamber –
Background 6 uR/hr; at bin 52 uR/hr; Ludlum 14c with pancake
G-M detector – at bin 1800 counts per minute.”
Report Number: NV110024
that once the suspected radioactive material, which had triggered
the alarm, was tested, it came in at a whopping 27.7 times background
according to a Ortec MicroDetective radiation detector.
is a good example of how proper protocol reaction can yield
an important result. It also confirms that anything that reads
three times background or above should be taken very seriously,
as seriously as the California Highway Patrol takes it.
this case, the Los Angeles Basin was being pelted with radioactive
rain at 4.15 times background or 115% above the CHP trigger!"

Frank Thompson: Your measurements are useful to all of us
provided that they’re accurately taken which, we assume,
they are. We don’t think what you found was a hot particle.
It more likely was radon progeny (though at over four times
background, your detection may have picked up something else
that could have come from Fukushima since three ongoing and
worsening meltdowns are the most obvious suspect). So keep
those measurements coming, Frank. Folks in Virginia, as well
as the rest of us, surely appreciate them.

wanted to know how to contact you about contributing rad reading
data from here in Virginia as I also have an Inspector Alert
and have been taking readings for a week or so now. Our avg
indoor is 40-44 and had taken a rain sample wiped from our
windshield after returning home during a recent rain on a
paper towel which hit 171 counts/min(1713 counts in 10 min).
It faded to about 45 after 5 hours or so. May have been a
hot particle. However, if this effort is not useful to you
on the West Coast let me know by email.
