16.03.2011: Contamination of foods and feedstuffs by nuclear accidents

The accident of Chernobyl provided a lot of knowledge on contamination of the food chain. These information can now be applied in the actual Japan nuclear disaster. It is important to avoid milk of cattle which received grass and fodder of the contaminated region. As most of the radioactive particles end up in the ocean it is imperious to avoid sea foods of any kind. Do not drink tap water. More personal protection measures are described below.

The food chain safety will be compromised in the next decades by the situation in Fukushima. Primarily drinking water in Japan and Pacific fish and seafood will bear an increased load of radionuclides.

Maximum permitted levels for foodstuffs and feedstuffs of European Regulation [1]

	Dairy products	Others
Isotopes of strontium (Sr-90)	125	750
Isotopes of iodine (I-131)	500	2.000
Alfa-emittinng isotopes of plutonium and transplutonium (Pu-239 Am-241)	20	80
All other nuclides of half-life greater than 10 days (Cs-134, Cs-137)	1.000	1.250

Other foodstuffs and Liquid foodstuffs [2]

	Baby foods	Dairy Products	Other Products	Liquid Foodstuffs
Isotopes Strontium SR-90	75	125	750	125
Isotopesof Iodine, I-131	150	500	2.000	500
Alpha-emitting isotopes of Plutonium and Transplutonium elements notably Pu-239, Am-241	1	20	80	20
All other nuclides of half-life greater than 10 days notably Cs-134, Cs-137	400	1.000	1.250	1.000

Maximum permitted levels are set too high [3]

Green MEPs believe the maximum permitted levels of radioactive contamination are set far too high and would leave the European public exposed to unacceptably high doses of radioactive contamination. Strontium-90 is absorbed by bone, which leads to bone cancer and leukemia, caesium-137 spreads throughout the body but favours muscle tissue, plutonium is primarily toxic when inhaled and causes lung cancer and thyroid cancer broke among children in Chernobyl which drank milk which was iodine-131 contaminated.

Minor Foodstuffs [4]

For the minor foodstuffs given in the Annex of Regulation 944/89, the maximum permitted levels to be applied are 10 times those applicable to 'other foodstuffs except minor foodstuffs' fixed in the Regulation No 3954/87. Minor foodstuffs are those of minor dietary importance which make only a marginal contribution to food consumption by the population.

List of minor foodstuffs: Garlic, truffels, capers (fresh, chilled, dried or as powder), manioc, arrowroot, salep, Jerusalem artichokes, sweet potatoes and similar roots and tubers with high starch or inulin content, fresh or dried, sago pith, peel of citrus fruit, curry and other spices, natural gums, agar-agar and other mucilages and thickeners, fats and oils and their fractions of fish or marine mammals, cocoa, yeasts baking powders, vitamins, essential oils.

Information to the public in case of a nuclear accident [5]

In case of a nuclear accident the public should be provided with the following informations.

- Information on the type of emergency which has occurred and, where possible, its characteristics (e.g. its origin, extent and probable development);

.- The various types of radiological emergency covered and their consequences for the general public and the environment. Basic facts about radioactivity and its effects on human beings and on the environment.

- Emergency measures envisaged to alert, protect and assist the general public in the event of a radiological emergency.

- Appropriate information on action to be taken by the general public in the event of a radiological emergency.

- an invitation to the population concerned to tune in to radio or television,

Advice on personal protection

Have iodine supplementation. Do not go outside, stay indoors. Close windows and make the house airtight. Do not turn on ventilators. Hang laundry indoors.

Use wet cloth to breath through.. Change often cloth. Use waterproof clothing to go outside. Wash hands often. Do not drink milk. Eat canned food. Avoid to drink tap water. Avoid seafood.

Export ban of foods and feedstuffs which exceed maximum radiation levels [6]

It is not acceptable to allow products with contamination levels in excess of the maximum permitted levels relating to products for consumption in the Community to be exported to third countries.

Feedstuffs, maximum permitted levels of radiation [7]

Maximum permitted levels of radioactive contamination of feedstuffs following a nuclear accident or any other case of radiological emergency:

Feedstuffs for max Bq/Kg

Pigs 1.250

Poultry, lamb, calves 2.500

Others 5.000

Radiation levels [8]

The International Atomic Energy Agency said after Tuesday's blast that radiation dosages of up to 400 millisieverts per hour had been recorded at the site.

Exposure to over 100 millisieverts a year is a level which can lead to cancer, according to the World Nuclear Association.

4.000 mSv (short exposure) causes 50% death rate.

7.000 mSv (short exposure) causes death

1.000 mSv/hour radiation level near Fukushima power plant 16.03.2011.

250 mSv (short exposure) causes radiation sickness (nausea, vomiting headache)

100 mSv (exposure during 1 year) causes 1% cancer

2,4 mSv (cosmic radiation of 1 year according UN)

13.03.2011: The accident of the nuclear power plant of Fukushima
Worldwide 99 accidents have been reported at nuclear power plants. Fifty-seven accidents have occurred since the Chernobyl disaster, and almost two-thirds (56 out of 99) of all nuclear-related accidents have occurred in the USA. Relatively few accidents involved fatalities. [1]

The accidents at the nuclear power plants in Japan creates the necessity to install worldwide nuclear accidents emergency response. For that valuable experience was gather from Hiroshima and Nagasaki and the explosion of Chernobyl.

Kukushima nuclear power plant is 40 years old. Experts say that in case of an explosion, similar to Chernobyl, fall-out of the lower layers of the atmosphere will contaminate whole Japan. The upper region of the atmosphere has east winds. Nuclides which get to these layers will be driven to the Pacific and may reach USA.

Immediate threat was radioactive iodine, with a half-life of eight days. Potassium iodine tablets may saturate the thyroid gland and are to avoid radioactive iodine to accumulate what may develop thyroid cancer. The contamination of atmosphere and soil with strontium-90 and caesium-137 has half-lives of about 30 years. Caesium-137 is being retained by the clay material of surface layers of the soil. However, contamination also migrates into underground aquifers and closed bodies of water such as lakes and ponds Plants like tress, mushrooms, grass, fruits, vegetables, insects ruminants and fish absorb radionuclides which enter the food chain.

After 20 years more than 80% of the activity of the fallout of Chernobyl was found by Ramzaev et al 2007 analysing the first 5 cm of the vegetation-soil cores of the forested landscapes. The low annual temperatures, clay-rich soil type with neutral pH, and presence of thick lichen-moss carpet are the factors which may hinder 137Cs transport down the soil profile. [2]

The team of Ramzaev also looked at the migration of caesium 137 and strontium 90 originated from underground nuclear explosions in the Russian Arctic. They found vertical migration of (90)Sr to be more rapid than that for (137)Cs, the depth was, however, limited to the top 10-20 cm due to permafrost conditions. The horizontal migration rate of radiostrontium in the aqueous phase exceeds the radiocaesium migration rate by many times, report the authors.[3]

More than 20 years after Chernobyl [4]

Twenty four years after the catastrophe, restriction orders remain in place in the production, transportation and consumption of food contaminated by Chernobyl fallout. In the UK, they remain in place on 369 farms covering 750 km(2) and 200,000 sheep. In parts of Sweden and Finland, restrictions are in place on stock animals, including reindeer, in natural and near-natural environments. "In certain regions of Germany, Austria, Italy, Sweden, Finland, Lithuania and Poland, wild game (including boar and deer), wild mushrooms, berries and carnivorous fish from lakes reach levels of several thousand Bq per kg of caesium-137", while "in Germany, caesium-137 levels in wild boar muscle reached 40,000 Bq/kg. The average level is 6,800 Bq/kg, more than ten times the EU limit of 600 Bq/kg", according to the TORCH 2006 report.

No safe level of radiation exposure

The current theory is that the relationship between dose and detrimental effect is linear without threshold down to zero dose. In other words, there is no safe level of radiation exposure, says the TORCH Report and concludes:

Cancer deaths, thyroid cancer, other solid cancers with long latency periods are beginning to appear 20 years after the accident. Belarus, Ukraine and Russia were heavily contaminated, but more than half of Chernobyl’s fallout was deposited outside these countries contaminating about 40% of Europe’s surface area.

Decisison support systems [5]

Several nuclear accident decision support systems are available which can be applied to complex networks of lakes, rivers and tributaries, such as MOIRA-PLUS. It is a computerised system for management support to Identify optimal remedial strategies for restoring radionuclide contaminated aquatic ecosystems and drainage areas in Italy. Monte 2011 presents an application of the decision system to 10 lakes and 18 rivers in Italy contaminated with (137)Cs of Chernobyl origin.

Assessment of the environmental and radiological consequences of a nuclear accident requires the management of a great deal of data and information as well as the use of predictive models. Computerised Decision Support Systems are essential to handle high volume of data in the management of freshwater ecosystems. [6]

Phase out of nuclear power plants in Germany

The nuclear accident in Japan reignites the discussion about nuclear power plants in Germany. Politicians of the Green Party bring forward the argument that the construction of German nuclear power plants present similar safety risks as those which caused the accident of Fukushima.

Emergency management in different countries [8]

Emergency Management is the generic name of an interdisciplinary field dealing with the strategic organizational management processes used to protect critical assets of an organization from hazard risks that can cause disasters or catastrophes, and to ensure their continuance within their planned lifetime. The whole system is based on theoretical rules which collapse whenever unexpected problems arise. Nuclear power plants should therefore not be constructed any more. Alternatives such as solar energy and wind turbines should be promoted as the clean energy for the next centuries.

30.01.2011: Climate change causes extreme weather conditions in Saudi Arabia [1]

A Saudi meteorologist, Mansour Al-Mazrouei of the King Abdulaziz University (KAU), predicts extreme weather conditions in the Kingdom in 2011. The region will be exposed to torrential rains, excessive heat or severe dry winds. Heavy rainfall is expected in Eastern Province, Qatar, Bahrain and Jeddah. Climate change causes serious problems for the region with eleven deaths during the recent heavy rains in Jeddah.

19.01.2011: Is the new Lithium-Metal-Polymer-battery with a load for 600 kilometres called „the new era of energy storage“a technology breaktrough, or was it just a dream? [1]

The German company DBM Energy is specialised in fork lift batteries. DBM Energy presented its lithium metal battery which is explosion proof, does not burn has a load for 600 km rage, has a staple life of 10 years and is ten times less expensive as the actual batteries derived from handy technology. It works in a temperature range of -40°C to 80°C.

The new technology “Lithium-Metal-Polymer-battery (LMP)”, marketed under Kolibri (Hummingbird) AlphaPolymerTechnology, was developed by Mirko Hannemann in Berlin. The bird name stands for energy efficiency. Hummingbirds can fly 800 km with only two gram of nectar. The Lithium-Ion-Battery which comes from the technology of handy and laptops, became famous in the Tesla car by Elon Musk, presenting 80 per cent of efficiency at its best. It will be replaced by the new LMP technology which presents 99,7 per cent of efficiency, with a car range of up to 600 km with one load. [2]

The reaction of the car industry and the ADAC Motorwelt German car magazine is highly sceptical toward the new battery. Germany car makers are hoping to get 4,5 Billion Euro subsidies for research in the field of car batteries next three years. With the LMP technology such rich subsidies will be unnecessary. According to Reinhard Kolke from the ADAC small companies have an advantage with small, rapid and creative development teams compared to lame great corporations. [3]

With a range of 600 km the DBM technology may, if it is not a fake, beat all established car makers which would be disgraced. Peugeot presented the E-car ION with a range of 130 km and 35 000 Euro cost. The Tesla Roadster from Elon Munck has a price of 90 000 Euro and needs recharging after 320 km. It seems that Hannemann may lead to a “new era of energy storage”.

Papstar says ADM battery is very good [4]

Papstar which has one DBM Energy battery on test on a fork lift says he ordered another 10 batteries. The DBM Energy battery performs better than conventional lead batteries and consumes definitely less energy than other battyry types.

A lot of irritation [5]

There is a lot of irritation going on related to several unclear facts concerning the battery and the 600 km test drive, which had been accompanied by Dr. Andreas Goerdeler, a principal of the Federal Ministry of Economics and Technology . Should the battery prove to be a fake it would turn out to be embarrasing for the Ministry. [3]

30.12.2010: Kuwait should abandon its nuclear plans, says energy expert [1]

Kuwait should abandon its plans to build a nuclear power plant together with French AREWA. Adnan Al-Shaheen of Al-Dal Company for Environment Projects, a Kuwait energy expert, recommends wind and solar energies as safe options.

Aside of being dangerous, nuclear energy directs Kuwait into dependence of uranium producing countries.

Alternative to nuclear dependence

Wind and solar energy, together with hydrogen technology as energy storage and clean fuel for transportation is the access to the new energy economy for arabian countries, The sunbelt of the Arabian deserts are an enormous wealth which can be added to the energy export porftfolio as additional clean energies.

The new energy economy

The technological developments are beating all records of prevision of financial experts. Modern cars powered by electricity and hydrogen are being subventioned by western governments. Electricity and hydrogen is replacing transportation on streets, railways and on water. Air traffic will further rely on kerosene. Crude oil will thus remain important for a long time, however, clean electricity and hydrogen will become a second source of revenues for the Arabian countries.

20.12.2010: CCS, a story of how bad environmental news laundering is being done [1]

E.ON Energy, an energy giant in Germany, constructs a small facility to test stack gas cleaning using CO2 separations by amine solvent absorption in Wilhelmshaven (Germany).

According to Dr. Holger Bräuer, head of the project, the pilot plant will have a capacity to wash 20.000 cubic metres/hour (5,5 MW) which is 1 per cent of the stack gases actually produced by the coal fired power plant at Wilhelmshaven. The pilot plant, with a budget of € 10 million, is being constructed in cooperation with Flour, a company of USA, using monoethanolamine (MEA) as a CO2 solvent. After capturing CO2 it will be released to the athmosphere, because the technology of storing the gas will only be available in 2020. [2]

MEA is rather weak base and will re-release H2S or CO2 when the scrubbing solution is heated and returns the regenerated MEA solution to the scrubber unit again for reuse after being cooled. This leads to a loss of efficiency of 11 per cent.

This meager projected outcomes of the CCS pilot plant of E.ON which does not tackle the problem how to handle CO2 after its capture is part of laundring bad climate news and will be used by the local newspaper to calm public oposition to a planen XXL-coal fired power plant at Wilhelmshaven. This is part of a broad public campaign taking place in USA and Germany wash green fossil fuel and avoid the emerging technology of solar energy, wind farm and hydrogen as energy storage and clean fuel for transportation.

A matter of price, says Siemens [4]

Pollution rights range from €10 to €20 per ton of CO2, are inexpensive and do not justify CCS technology.Only when costs rise above €40, separateion, transport, and storage of CO2 will be attractive to power plant operators.

04.12.2010: USA presents no commitment to legal targets at Cancun [1]

Dr Anna Korppoo, the programme director at the Helsinki-based Finnish Institute of International Affairs does not have any hope for a breakthrough in Cancun.

Professor Daniel Esty, who teaches at the Yale Law School and the Yale School of Forestry and Environmental Studies points to the fact that no country can solve the problem on its own. International agreements are therefore vital for a success in Climate protection. As a developing nation, China is not obliged to commit to any legal emissions cuts. Should the USA be able to overcome its political lameness and come with anything concrete at the negotiating table, China might move toward commitment as well.

Nuclear business overshadows environmental efforts [2]

The French president Sarkozy in December is on selling tour in India. Initial sell of two AREWA European pressure reactors will be upgraded to six in numbers, starting the implementation of the 10,000MW nuclear project. Nuclear energy would be the “focus” of Indo-French cooperation, he said, lauding the “considerable environmental benefit” and “energy independence” that it brought. As much as 80 per cent of France's electricity came from nuclear source. India's decision to expand its nuclear energy production from 4,000 to 62,000 megawatts in 20 years represents a “change of attitude.” However, Sarkozy did not mention the dangers of nuclear energy. It creates nuclear waste for billion of years. Germany is having a hard time to handle its nuclear waste. Other countries have no plans to solve the problem. Here again, big business is being done on cost of future generation. Read more

Facing the future of global energy: About 60 per cent of greenhouse emissions came from the energy sector. Solar energy and wind power may provide safe energies. [3]

Meanwhile consciousness and willingness to tackle climate issues are rising in the arabian countries. Abu Dhabi became the headquarters of the International Renewable Energy Agency (IRENA).

According to Hermann Scheer neither the United Nations nore the International Energy Agency. provides sufficient focus on renewable energy. Sheer was a member of the SPD party and member of the German parliament who first called for IRENA's formation in 1990. [4]

Adnan Amin, director of IRENA reports the development of a map bearing informations on insolation and wind velocity around the world clarifying of renewable energy potential of the different regions to increase the efficiency of the green activities of the countries, and may help government in their decision.

This highlights, for instance, the inefficient way Germany is handling photovoltaic with only 1000 hours of sunshine per year compared with 3000 hours in the sunbelt of the Arabian countries. Speaking about efficiency Germany should concentrate on wind power, of which it has plenty enough. Its engagement in photovoltaic should be focused on cooperation with Arabic countries which have a threefold efficiency in photovoltaic.

Carbon-based fuels present serious repercussions for the environment and public health. Adnan Amin calls on the international community to come together in a common effort to transform the energy system in the coming decades. This means to overcome the animosity and differences between possible partners to form effective cooperation in the field of solar and wind resources.

The Middle East and African countries have been active on this issue. Morocco had a renewables target of eight per cent of primary energy by 2012, Algeria achieved a 10 per cent share in 2008, while Jordan had set a target of seven per cent by 2015 and 10 per cent by 2020, said Amin.
