ODA diffuses radiocative bunker fears at Olympics site

He adds: "In the cleaning and clearing of the Olympic Park, much of it contaminated through decades of industrial use, we have reused over 80 per cent of previously contaminated soil that we excavated and recycle or store of reuse over 90 per cent of demolition materials.
"As we announced last year small amounts of material containing low level radioactive elements was found during the clean up of the site. In accordance with Environment Agency guidance a small amount of soil containing traces of this very low level radioactive material, classed as 'exempt' under current environmental law, has been safely buried in a cell under a bridge embankment on site. It is covered and capped on all sides. This safe disposal has been approved by the Environment Agency and the legacy landowner the London Development Agency and in no way poses a risk to the health of the workforce or public now or in the future."
He also scarily points out that spending an hour on a plane would give a dose of radiation that was 1,000 times the exposure from the buried material.
Not being an expert in any way on these matters I am presuming for now that visitors to the site have nothing to worry about. And Certainly the ODA did readily admit that radioactive waste had been discovered at the site back in October 2007 as this Reuters report verifies, although I can't find much about them saying anything about some of that waste being would buried next to the stadium.
Any way, I'll certainly be keeping an eye on this in case it becomes more of an issue in the coming years.
