From Nikkei Shinbun (5/19/2011):

With all that is happening and the revelations, I wonder if you could help to write article on:
1. what happens now for those living out of Fukushima, particularly in Kanto area? Not much news other than they are finding more plants contaminated. I doubt it's just tea leaves at this point, right?
2. do we still have risks of explosions as a result of the meltdowns, aka. China Syndrome? if yes, what would be the magnitude? I can't seem to find info on this anywhere.

Thanks for taking the recommendation, you can't tell how appreciate I am of what you are doing.

Some links, if you dont know them.;O=D

For France, now, it's OK, (some readers of my blog keep watch on measures with Geiger counters and convey every day.)

1. The characteristic pattern you will see on maps of radiation is "leopard spots".
They will be finding radiation hotspots for years to come. It will lead to odd situations, where, say, crops from one rice paddy will need to be treated as radwaste, while the neighboring cabbage patch will turn up clean.

Testing MUST be stepped up and kept up, on the entire island at least, because the radioactive Cesium is quite mobile, it gets dissolved in water, goes up as fog, back down in rain etc.
My advice to you, if you live in Japan: do what you can to help with testing, screening and education.

Organize a buyers' co-op to screen farm produce. Get a detector and go hotspot-hunting in your neighborhood on weekends. Get active in the political arena, try to make labeling the origin of food mandatory.

Get informed, most importantly. Inform others, but ONLY when you feel you have sufficient grasp of the subject matter. Radiation safety is not very complicated, but it's easy to scare people out of their wits.

2. Stop it with the China syndrome already. It's Chile, anyway, not China.

No matter how deep the corium is right now, in the three reactors, it is being cooled. It will be hot for a year or even more, so they will continue to pour water and make radioactive steam.

If we're lucky, they should be able to direct that steam to some condensers, some time in August and the worst of the airborne pollution will stop.

Explosions from corium hitting water will almost certainly not happen, they would have happened already. There may still be explosions and fires from hydrogen or from the corium igniting something or maybe even from electrical equipment left outdoors, in the monsoon). All these would spread some more radioactive pollution.

Oh, btw. This is most important. Operate in yourself a change of mindset. It is not "radiation" you are fighting. It is pollution.

You are not in danger to drop dead from prompt beta+gamma due to massive fallout. You are in somewhat elevated risk of cancer from pollutants in the environment. These pollutants happen to be easier to detect than mercury or dioxin. You only need a Geiger counter to do an initial assessment.

Sure, it gets complicated when you want to find out what exactly is in there, but for keeping safe, a detector and some care in selecting food sources is adequate for risk mitigation.

Oh. One more thing. Plants are able to use some of the radiation - it's just light, after all. They tend to grow bigger than usual because of this extra light. If you see a radish twice normal size in the market, don't buy it.

Radioactive iodine from Fukushima Daiichi a threat to unborn children

Exposure to I-131 causes significant increase in infant mortality.

Of all the risks associated with TEPCO's power plant there is one that I have not seen any discussion of and that is the problem of wild animals be they bird, fish, mammal or reptile.

In the early days after the 3/11 disaster there were reports of birds dining on fish stranded on the grounds of the Fukushima power plant by the tsunami. These birds would have been flying through the worst radioactive plumes, roosting on the shattered reactor building structures or landing amongst the debris to feed. This situation presumably continuese to this day.

Other creatures such as rodents, animals that prey on rodents, lizards, stray domestic cats and dogs even flies and insects have had free access to buildings and grounds of Fukushima Daichi. Fish in the surrounding waters have been swimming in highly radioactive waters and some may have died, washed ashore and have been eaten by gulls and other scavangers. These creatures are not static. They are quite mobile and could end up many miles from the official contaminated zone.

Consider a person living many miles from the affected area coming out in the morning to find a seagull has left its droppings on his car. The victim of the aerial fecal bombardment goes and gets a paper towel to wipe the mess off his car not knowing that that bird may have been very radioactive! Have the authorities given any thought to this or do they consider it not a serious problem?

I cover the animal contamination subject in a past post that magically disappeared during the last purge. Unfortunately Fukushima isn't the only place where animals are contaminated by radioactive waste.

"The inspector was responding to complaints about the pigeons being a health hazard by the local community and rumours that they could be radioactive as a result of roosting at Sellafield. (Renamed from Windscale site of one of Britian's worst nuclear accidents).

A BNFL spokeswoman confirmed they had tested around 150 of the dead birds and found significant levels of radiation." (Decades after the accident was supposed to be cleaned up).

Radioactive animals are common in the huge nuclear wastelands of Hanford Washington, Savannah river South Carolina among other lesser known sites. These animals find their way off the reservation all the time. The government monitors the animals to gauge local contamination.

IMO the people in the effected region will be marginalized and forgotten as soon as possible. People who exhibit symptoms of radiation exposure will be told they have radiation phobia and their illness is related to stress and not unquantified exposure. This was the case after Chernobyl "it all in your head" was accepted by the WHO and the IAEA as a valid explanation. Some phobia supporters went as far as to claim Europe experienced massive abortions due to radiation fears. But records show little if any excess abortion compared to the years before Chernobyl. Radiation phobia has been slowly losing supporters as it is discredited by time but no reason it can't be revived in Japan.

2) I think it is really impossible to determine the risks of further explosions but it doesn't look good. TEPCO has been attempting various explosion mitigation protocols like nitrogen purges so it seems they are still concern with excess hydrogen/oxygen production.

A variation of the China syndrome is always possible until the nuclear fuel is brought under control but a huge white hot mass melting through to the water table probably won't happen. The magnitude would depend on the volume of fuel involved and the configuration it takes. Certain shapes can magnify neutron activity you can't just pour fissionable material into any shaped container you like. Some shapes increase activity and some diminish it. If the fuel becomes dispersed and diluted it may just horribly contaminated the immediate vicinity below the RPV. If the corium collects into a large enough mass It could breach the foundation. The lack of information on the subject is due to the fact everything is just an educated guess with too many unknown variables to give a definitive answer.
