Potential dispersion of the radioactive cloud over The Northern Hemisphere
These animations display a potential dispersion of the radioactive cloud (Caesium 137 Isotope) after a nuclear accident in reactor Fukushima I. The continuous release rate is very uncertain, thus the calculations have to be interpreted qualitatively. Dispersion in the near surface level (Level 1), in appr. 2500 m height (Level 12) and in appr. 5000 m height (Level 16).
The release rate is estimated as 1015 Bq/d. This is appr. one tenth of the Chernobyl release. This simulation is a so called “worst case scenario” with continuous release rate. The value of 0.1 Bq/m3 correspond to appr. one millionth of the concentration at the source. At distances more than appr. 2000 km away from the source, the concentrations are not harmful to health.
The simulation starts fictitious at 15.03. 00 UTC and will continue to run in order to demonstrate the intercontinental transport. When exact relaese rates are published we will restart the simulation with reliable values.

USA Today ‘Debates’ Nuclear Power
Bob: I grew up in his home state near one of the country’s oldest nuclear power plants (the Connecticut Yankee plant), and in all its years of operation–like virtually every other nuclear plant in the world–not a single life-threatening event has occurred.
Cal: And you told me you used to swim in the warm water generated by that plant. No wonder you became a liberal!

THE LOW LEVEL RADIATION CAMPAIGN
…”In the USA radiation has reportedly been detected, but the consistent official response is reassuring. However, Environmental Protection Agency monitoring data has vanished from the web. In Canada there remains no official public statement about the risk to Canadians of inhaling the contaminants. Official advice about At what dose might health effects occur? is bland and misleading. The real answer is that no dose is safe, and Plutonium and Uranium are very dangerous if inhaled or ingested, even though assessed “doses” might be very low. At present we have no way of knowing whether these elements are reaching the west coast of the Americas….”
