We research the health effects of ionising radiation
We demand a re-evaluation of the risks of radioactive pollution

417,000 cancers forecast for Fukushima 200 km contamination zone by 2061
Scientific Secretary of the European Committee on Radiation Risk (ECRR), Professor Chris Busby, has released calculations of the cancer incidence to be expected in fallout areas of Japan. Using data from the International Atomic Energy Agency and official Japanese web sites he has used two methods to estimate the numbers of cancer cases. He compares these results with estimates derived from ICRP modelling.


Thursday 31st March Beta monitoring on USA western seaboard

radnet graph 23-31 march 2011 showing beta peak in california 30th March We have not been able to access Radnet April 2nd to update this graph
This data from Radnet, captured 31 

 March at 11.30 UTC updates the previous day’s late posting. The daily trend of rising beta radiation during the day, with a reduction at night has continued. We speculate that this may be due to onshore winds during the daytime, and offshore winds at night. Email us if you know something we don’t. The peak values have clearly increased over the last four days.


Wednesday 23rd March
Fukushima 70 kilometre contamination levels twice as high as Chernobyl Permanent Control Zone.
Honshu should be evacuated.

The IAEA website yesterday revealed beta-gamma contamination measurements taken between 35 and 68 km from Fukushima. The results ranged from 0.08 to 0.9 MegaBecquerels per square metre (MBq/m2). The Chernobyl Permanent Control Zone was contaminated up to 0.55 MBq/m2. The highest level of contamination classified after Chernobyl was greater than 1.48 MBq/m2. The data for Chernobyl were for Caesium and the same is probably true for the Fukushima data. All official agencies are conspicuously silent about the alpha-emitters Plutonium and Uranium. We remain deeply concerned about this lack of information.

Yesterday the US Environmental Protection Agency said a sampling filter in Hawaii had detected minuscule levels of an isotope that is also consistent with the Japanese nuclear incident. The filter was being sent for further analysis.

fukushima fallout plume affects Tokyo 14-15 March 2011 How the fallout was distributed

The animation is a continuous loop showing the plume from Reactor 3 (MOX fuel) at hourly intervals from midnight 14 March to 3 a.m. 15th March. Fukushima is in the middle of the picture. To the right is the Pacific, left is inland. Tokyo is south-west of the wrecked reactors, under the plume in the final frames shown here.
