The Cancer of Fukushima

Nuclear power is something of an emotive subject in Japan following the disastrous multiple meltdowns at the Fukushima Dai-ichi plant in March 2011 and subsequent contamination of the local region by what was, in effect, a massive dirty bomb. Since then, every reactor in Japan has been taken off-line for "maintenance" though Sendai (in southern Kyushu) was brought back to life over summer and Tsuruga, on the Japan sea coast, is currently pushing to restart its engines too. And without them The Maldives is soon going to be a new Atlantis.

Public concern has been recently heightened by reports of the first worker to develop cancer through exposure to radiation at Fukushima itself. Except, despite the headlines, he didn't as far as anyone knows. With 40,000 workers at the site, the average cancer rates in Japan suggest at least 200 would develop cancer annually without any man-made encouragement. The unlucky individual, with a dose of 15,700 microsieverts, has been awarded workers compensation for falling ill and being able to prove he received a dose higher than that legally mandated. Despite the headlines, no one is actually claiming there is a causal link between his illness and exposure to radiation. He was just smart enough to fill in the correct claim forms. 

Indeed, workers in the US are deemed at no risk working in an environment with ten times the radiation levels of the Japanese government stipulated safety levels. To date, no single person has died as a direct result of exposure to radiation from Fukushima. But the suicide rates of those displaced in the evacuation are very real and increasing. With a construction boom in Tokyo pulling workers away from rebuilding Tohoku and allocated funds sitting unused in government coffers, perhaps it's time to worry a little less about the design of the new National Stadium and instead help those who four years later are still living in shelters. Just a thought.


Evacuees still remain in temporary shelters after four years

The radioactive fallout of a consensus based society

A consensus based society, in theory, has a number of significant advantages. For example, although there are compulsory purchase laws in place to force the sale of a property, the government prefers not to use them but rather come to an understanding with all involved before a development proceeds. Anyone who has had to sit on an airplane at Narita airport for thirty minutes whilst it taxis to Runway Two has had to experience the pleasure of this particular compromise.

A more recent implication though relates to the continuing decontamination following the Fukushima dirty bombs. Top soil, removed from the towns and villages unlucky enough to have been downwind the day the reactors buildings went skyward, had been scraped away and collected into large vinyl storage totes (bags), each weighing around a ton. And then consensus kicked in and no one knew where to put them so they were piled high on a beach front in Tomioka.

In the recent flooding (of biblical proportions) that came following the rains and typhoons of recent days, nearly 300 of these totes were washed into a nearby river, of which only approximately 200 have so far been recovered. Sadly, this is a case where consensus has a very high cost. No one in their right mind would actually want this material stored near them, but someone had to draw the short straw. The alternative is now floating out to sea in a large, black, plastic bag. Possibly easy to see at night though...

The flotsam and jetsam of Fukushima

"Highly radioactive" is a somewhat emotional phrase being regularly applied to the debris drawn into the Pacific Ocean after the tsunami of March 2011. Although elements of this disaster have been washing up on the shores of the west coast of North America for quite some time now, recently the first traces of radiation, identified to come from Fukushima, have also been identified along the Oregon shores. You needed to read a long way into the reports to see the levels were fractions of fractions of a percent of the everyday background radiation. Not really something to worry about but it makes a great headline.

The debris field is the remnants of millions of tons of the everyday items that made up the towns and villages of the Tohoku coast that was scoured away that day. Whole habitats simply disappeared along with everything they contained. A football crossed the oceans quickly and was emotionally returned to its owner months later. A motorbike, a Hog, kept in a weather-proof plastic garden shed landed in British Columbia and was refurbished and presented to a delighted owner. The wreckage of floating docks, ghost ships, houses and even fishing tanks with live fish still in them (hmmm, I question that one) regularly wash up on the shores of the Pacific countries now.

The debris itself set off on its sojourn across the oceans in the days before the meltdown at Fukushima and is generally not considered to be radioactive or pose a risk of wild mutation. What it does carry is the ability to pollute the shorelines when the wreckage comes to rest and potentially this poses an even greater risk is to wildlife. The flotsam carries with it hitchhikers, species native to the waters of Japan but that were not necessarily established elsewhere. Although the process of ocean current transfer has always existed, this time it is on a scale never seen before. Radiation isn't the problem, fare dodging passengers are. This could be an ocean wide environmental disaster to follow the natural one of 2.42, March 11, 2011. But it just might be forgotten until it's too late.

The sorrow of Fukushima

March 11, 2011 saw one histories greatest earthquakes. I use the word "great" here in the sense of scale; there was nothing good that actually came from it. The devastation it unleashed on the Tohoku coast line will scar the region for decades to come with many areas unlikely to ever be rebuilt or recover as the younger generation looks to the cities further south to start a new life. Many communities were declining before the events that day, now they're in free fall.

Fukushima Daiichi Nuclear Power Plant remains a catastrophe area with exclusion zones still in place. Decommissioning will not begin for many years to come and the technology required doesn't exit for much of the process. But the meltdown at Fukushima caused a secondary issue, it became a "distraction" to the real and present crisis. The meltdown and radiation released forced the relocation of many thousands of people but the tsunami forced the relocation of hundreds of thousands when nearly twenty thousand died in the tsunami within minutes of the earthquake. 

Over a million buildings were partially or totally destroyed by the combined effects of the temblor and black wall of water and in many areas the reconstruction process has hardly begun. And the world and Japan remain focussed on the one issue, Fukushima. The sense of urgency has left the country though 170,000 still live in temporary housing. The Mayor of Rikuzentakata has issued an open invitation for anyone to visit and maybe a little gaiatsu, external pressure, might help things along. To paraphrase The Economist, "what will all the foreigners think when they come for the Olympics?".  It's been four years, that should have been enough.

Just run. Run uphill. Don't worry about the others. Save yourself first. And tell the future generations that a tsunami once reached this point. And that those who survived were those who ran. Uphill. 
So run! Run uphill!

Nuclear power, earthquakes, tsunamis and the choices for Japan. And the planet.

This blog is designed and deliberately written to be family friendly. As such, here, I don't tackle controversial subjects and don't aim to argue subjective points. I simply set out to explain interesting aspects of life in Japan. And following a couple of major earthquakes over the last few days which always re-ignites the debate, here we go on nuclear power….

Before the earthquake of March 2011, approximately 30% of Japan's electricity was generated by the nuclear industry. Soon after, all 100+ reactor cores were shut down for politically acceptable "maintenance". And since then Japan has been looking for an alternative. Scrambling that first summer the country brought older power stations out of mothballs, started to import vast quantities of oil and natural gas and even plugged two massive floating generators used for powering oil rigs into the Tokyo grid.

Whilst renewables are obviously a good idea, the lack of power storage systems means they will remain marginal until that issue is resolved. Tidal power is beginning to develop, wind farms are progressing and even micro-hydro plants used in irrigation of rice fields are growing in popularity. But in reality major schemes such as terawatt hydroelectric damns (which produce significant greenhouse gasses through decay of foliage by the way) are years if not decades away. So the question is, do we continue to burn fossil fuels and risk the atmosphere, or do we switch the nuclear power back on and risk the land? Or alternatively do we switch off the lights and use less power?

Before the earthquake; Tokyo's lights are bright and vibrant

Tokyo after the quake. People switched off those lights to save power.

You can track earthquakes in Japan too

On Wednesday we experienced another aftershock in Japan, an echo of the M9.0 from March 2011. I posted a map showing the 949 quakes over M5.0 we've experienced since then and had several questions asking where did I find the data. Very simple, soon after the earthquake a developer called Paul Nicholls created a real time map linked into the Japan sensor network; it became something of a hobby tracking the shocks as we were thrown sideways on a regular basis. Here is a follow-up image showing all 3,234 quakes (as of 5.00PM today) we've had the pleasure to host since then and if you'd like to follow this site just go to Japanquakemap.com. And thank you to Paul for creating this site.

However, if you'd like to be a little more proactive following earthquakes in Japan then download this App, Yurekuru ("Earthquake Coming"). In the settings you can choose where in Japan you'd like to follow and the level of quake you'd be concerned about. Mine is set to Shibuya in central Tokyo and only alerts me for anything over M5.0. Below that doesn't seem too exciting these days.

The system is linked again into the government sensor network. When an earthquake is detected it issues an alert across the entire data network and you'll receive a few seconds warning. 

A few seconds doesn't sound much but it's about the time it takes for you to stop watching TV and get to the children's room to ensure they're safe and not scared. At those moments ten seconds is akin to an eternity.

And so if you're sitting in New York and have family in Fukushima, it will still work. And you can track when we're running to the kids' room to check they're ok and hopefully watching them quietly fall back to sleep.

Aftershock - the battered coastline of Fukushima

10.51 this morning and the house started to move again. The first p-wave came through as a sudden jolt followed by the s-wave, the slow rolling tremor that causes the real damage. Fortunately it wasn't too strong but at about thirty seconds it was obvious somewhere wasn't having a good time. Checking the earthquake App on my phone I can see the epicentre was just off the coast of Fukushima. Again.

The earthquake of March 11, 2011 was a little further north than Fukushima but close enough to change the way the world sees nuclear power. And then the aftershocks continued to pound the coastline over the next few months, slowly reducing in frequency but not actually coming to a final halt. Today's quake was a M5.4, not large by Japan standards but enough to rattle Tokyo some 300km away. 

The map below doesn't show all the earthquakes to hit Japan post 3/11. It only shows the 949 we've experienced over M5.0. In all there have been over 3,000 since the main quake. And on the Tohoku coastline, just about dead centre in the area covered with dots, is the Fukushima Daiichi Nuclear Power Station. Much closer to the action, they won't have been having a good morning.

Fifty Six Days - The story of an earthquake in Japan


It was fifty-six days from the moment the earth sent its first warning of the catastrophe to come until the day it took a brief pause for breath. Fifty-six days that saw one of history's most violent earthquakes and tsunami followed ultimately by the nuclear disaster that threatened Tokyo itself. 

And this is the story of how it unfurled around me. 

Fifty-six days.
