Most of the radioactive particles are in the soil rather than in the flammable leaf litter and trees,

he explains. The fires that are currently burning are outside the 30-kilometre exclusion zone around Chernobyl,

Wildlife threatened by Fukushima radiation: Nature Newsradiation released by the tsunami-struck Fukushima Daiichi nuclear power plant could have long-lasting consequences for the natural environment in the vicinity of the damaged Plant scientists estimate that in the first 30 days after the accident on 11 march, trees,

birds and forest-dwelling mammals were exposed to daily doses up to 100 times greater -and fish and marine algae to doses several thousand times greater-than are considered generally safe.

with iodine-131 and caesium-137 being the most abundant (see'Radiation release will hit marine life').

A becquerel is defined as one radioactive decay per second. The team then plugged those concentrations into a piece of software called ERICA (Environmental Risk from Ionising Contaminants) to calculate the radiation dose that various groups of wildlife would have received.

ERICA accounts for factors that are known to affect the rate at which organisms absorb radioisotopes,

The dose rate (measured in milligrays per day) specifies how much radiation is absorbed per kilogram of organic tissue per day

a more biologically meaningful indication of how organisms are affected by exposure to radioactivity. Even so, it's just a rough assessment,

The team found that flatfish, molluscs, crustaceans and brown seaweed offshore of Fukushima received radiation doses that,

but they also give researchers a unique opportunity to study the effects of radiation on populations that would be impossible to recreate in the lab. Tim Mousseau,

together with an international team, is studying the long-term ecological and health consequences of the 1986 accident at the Chernobyl nuclear power plant in the Ukraine.

finds that bird species with orange feathers living in the fallout zone seem to be more susceptible to radiation than their drabber gray and black fellows1.

otherwise confer protection against radiation damage, and that this molecular trade-off is shaping bird populations around the former nuclear power plant.

One of the team, Anders M ¸ller from the Pierre and Marie Curie University in Paris, donned a radiation-protection suit to make four bird-watching trips between 2006 and 2009 to the Red

Forest and other locations around Chernobyl. In a 2007 analysis of the data from the first bird counts made in spring 2006,

and red carotenoid-based pigments showed a decline in abundance as radiation levels increased, though there was no comparable correlation for bird species with melanin-based colouring, such as brown, black and reddish-brown2.

Making phaeomelanin consumes large amounts of a tripeptide called glutathione (GSH) which is an antioxidant molecule that can also protect tissues from radiation damage by mopping up free radicals.

making it more susceptible to radiation. The researchers reanalysed the survey data on 97 bird species in search of differences between orange-brown birds, assigned a phaeomelanin score from 0 to 5 depending on the intensity and extent of the colours,

Eumelanin levels, it turned out, had no correlation with bird abundance in relation to background radiation, but birds with relatively high levels of phaeomelanin became rarer as radiation levels increased.

Biologist Kevin Mcgraw of Arizona State university in Tempe says that pigments are good ecological tools:

Mousseau is now in talks with Japanese colleagues to plan studies there following the disaster at the Fukushima nuclear power plant.

says that although the radioactive elements released at Fukushima are different from those released at Chernobyl,

and contained low levels of radiation around 9 Â becquerels per kilogram (Bq kg-1;

Furthermore, most of the radiation had accumulated on the leaves and could be washed off, suggesting that the plants were not absorbing dangerous levels of radioisotopes directly from the soil.

with most of the radiation in plants accumulated on their surfaces. Wheat leaves that were open at the time of the greatest fallout were contaminated heavily,

Wheat ears from these plants contained 300-500 Bq kg-1 within the prescribed radiation limit.

but suggests that cleaning up the more radioactive public spaces in Fukushima prefecture will not be easy.
