This is the "final update" for the UK on Fuku and has no air monitoring more recent than 1 July--so conveniently misses out the spikes seen across the US in the early days of July.
Interesting how they say cesium 137 is "routinely" observed at Seascale, Cumbria, near the Sellafield nuke plant. I'm sure that's a great comfort to the residents there.
