Radionuclide levels in fish off Fukushima are highly variable but remain elevated, indicating a continuing source of radiation.
Elevated radiation levels have been detected at and around the stricken nuclear power station in Japan, but the Chernobyl accident remains far more catastrophic
Steve Wing, an epidemiologist from the University of North Carolina, Chapel Hill, points out that even the low levels of radiation that remain in the environment could be significant in the long run «because so many more people are exposed, even though the dose per person decreases farther from the plant.»
A treated cat has to remain hospitalized until the radiation level has fallen to within acceptable limits.

The reduction in CO2 - cooling (of a layer between TOA and some other level) assumes the increased downward emission at the base of the layer from the non-CO2 absorber within the layer is greater than the decreased OLR at TOA, which is the absorption of radiation from below the layer minus the emission from the layer reaching TOA (refering to the «baseline effects» that would remain if the preexisting CO2 were removed).
The time scales involved remain miniscule on the level of an individual molecule BUT on a planetary scale they become highly significant and build up to a measurable delay between arrival of solar radiant energy and its release to space as outgoing radiation.
«This H2O negative - feedback effect on CO2 is ignored in models that assume that warm moist air does not rise and form sunlight - reflecting clouds, but remains as humid air near sea level, absorbing infrared radiation from the sun, and approximately doubling the temperature rises predicted from atmospheric CO2 increases.
What we know of the connection between solar activity and radiation, coupled with high abundances of isotopes in tree - rings and ice - cores (Fig. 2d), supports the likely case that during the Maunder Minimum solar activity remained for over half a century at very low levels.
