Fukushima accident released radioactive iodine in foods, drinking water of Tokyo citizens

This study concludes that the average cancer risks presented by I-131 intake of Tokyo citizens due to the Fukushima reactor accident are  lower than the annual risks of traffic accidents, naturally occurring radioactive material (potassium 40), and environmental pollutants such as diesel exhaust particles. Even so, this will not be comforting to the affected citizens and to those opposed to nuclear power.

Murakami, M., and Oki, T. 2012. Estimation of thyroid doses and health risks resulting from the intake of radioactive iodine in foods and drinking water by the citizens of Tokyo after the Fukushima nuclear accident. Chemosphere. Mar 2.

Abstract: The release of radioactive materials from the Fukushima nuclear power plant after the Great East Japan Earthquake on 11 March 2011 poses health risks. In this study, the intake of iodine 131 (I-131) in drinking water and foods (milk, dairy products, and vegetables) by citizens of Tokyo was estimated. The effects of countermeasures (restrictions on the distribution of foods and the distribution of bottled water for infants) on reducing intake were also evaluated. The average thyroid equivalent doses without countermeasures from 21 March 2011 were 0.42mSv in adults, 1.49mSv in children, and 2.08mSv in infants. Those with countermeasures were 0.28, 0.97, and 1.14mSv respectively, reductions of 33%, 35%, and 45%. Drinking water contributed more to intake by adults and children than foods. The intake of I-131 within the first 2weeks was more than 80% of the estimated intake, owing to its short half-life, indicating that rapid countermeasures are important in reducing intake. The average risks of cancer incidence and mortality due to I-131 for infants were estimated to be 3×10(-5) and 0.2×10(-5), respectively, lower than the annual risks of traffic accidents, naturally occurring radioactive material (potassium 40), and environmental pollutants such as diesel exhaust particles.

Health impact of Fukushima reactor accident expected to be limited to Japan

“The public health risk for populations in and outside of Japan has been closely monitored. The health impact of the accident is expected to be restricted to Japan. To date, no radiation injuries have been reported as a result of the accident. This is a major difference from the Chernobyl accident, where nearly 30 emergency workers died in the first weeks after the accident from the effects of acute exposure to radiation. However, as for the Chernobyl accident, the psychological impact of this accident may outweigh any other health consequences.”

Abstract: The World Health Organization (WHO) has responded to the 2011 East-Japan earthquake and tsunami through the three levels of its decentralised structure. It has provided public health advice regarding a number of issues relating to protective measures, potassium iodide use, as well as safety of food and drinking water, mental health, travel, tourism, and trade. WHO is currently developing an initial health risk assessment linked to a preliminary evaluation of radiation exposure around the world from the Fukushima Daiichi nuclear accident. Lessons learned from this disaster are likely to help future emergency response to multi-faceted disasters.

Australia coastline does not show signs of accelerating sea level rise

Tide guages do not show signs of accelerated sea level rise…..

Boretti, A. 2012. Is there any support in the long term tide gauge data to the claims that parts of Sydney will be swamped by rising sea levels? Coastal Engineering. http://dx.doi.org/10.1016/j.coastaleng.2012.01.006,

Abstract: The government of Australia is supporting the statement that sea levels are rising faster than ever before as a result of increased carbon dioxide emissions. Consequent to this, low-lying coastal areas, where the majority of Australians are concentrated, have been declared at risk of sea level inundations. Maps with 0.5, 0.8 and 1.1 m sea level rise have been proposed for Sydney, the major Australian city. However, long term tide gauges, recording sea levels worldwide, as well as along the coastline of Australia, and within the bay of Sydney, do not show any sign of accelerating sea level rises at present time.

Gleick pivots to focus on water….

Several  people have noted with surprise that Peter Gleick is still being given a platform to speak on water issues…..most recently the California Water Policy Conference as key note speaker (click here).

This should not be a surprise….I’m not sure why, but some water utilities in California and the state like to hear from Gleick on water policy issues and they will continue to do so because key personel in these water systems think very much the same way as he…….Gleick leveraged to gain support from water utilities by publishing a study that condemns bottled water and supports tap water in the name of sustainability……click here. I suspect that Gleick’s appearance is due to California democrat politics….Water policy planners count on political support for a place at the podium, not necessarily having any technical qualifications. But it’s their organization or conference, so utilities are free to choose anyone they care to as a key note speaker.

A group of large water systems formed the Water Utility Climate Alliance (click here) and many of these utilities have great influence in California water policy….as well as promoting global warming views in other water groups.

Similar industry groups like the American Water Works Association, Water Research Foundation, AWWA Research Foundation, and the Association of Metropolitan Water Agencies, have over the years fed their members primarily one set of  views on global warming. These are highly political organizations, and if their members want to promote global warming then they will and are free to do so…..that is just the way it is in the US water utility industry (science is in there sometimes, but balance on climate is often lacking)…..perhaps a few clear examples will help….but that for another time…

Human engineering to prevent climate change: Tyranny at its worst

Now climate activists are proposing that humans be re-engineered to be shorter and more climate friendly….click here….and click here for more discussion….so the Climate MasterMinds are now going so far as to try to create a super-race…..have we seen this before? This is fantasy….not philosopy….Tyranny….not liberty….

No global warming for 17 years….

Using the RSS data (click here) there has been no global warming for 17 years….and counting….
