Following the Chernobyl reactor fire in April 1986, acute irradiation caused complete decay of pine trees in forest located in direct vicinity of ChNPP. The so-called "Red Forest", a 1500 ha of Scots pine stand where the absorbed doses values exceeded the destructive value for coniferous species (> 60 Gy), is still today one of the most contaminated terrestrial ecosystems on Earth. Emergency clean-up activities consisted of in situ burial of contaminated topsoil layers and dead trees in about two hundred sub-surface trenches involving 1 million m3 of radioactive materials. The trenches of Red Forest waste dump were then covered with 20-30 cm layer of "clean" sand and the site was revegetated with a mixture of pine, birch and bushes to prevent secondary contamination due to soil erosion or wind resuspension (Kozubov and Taskaev, 2002).
