A few weeks ago I wrote about the possibility that global winds may well bring some of the radioactive fallout from the Fukushima nuclear plant in Japan towards the UK.
The Met Office computer models would be tracking any threats. I was not surprised to read that some of the radiation in the form of Iodine 131, a trace element from the plant, has been found across much of Europe, Scotland and in Oxfordshire. These particles have been carried on global winds, perhaps even by aircraft, and deposited around the globe. We know it has come from Japan because Iodine 131 is only present in the reactor. It has to be stressed this was expected and poses no threat and is less than would normally be found naturally in background radiation. It does show us that we are all part of a linked global system when it comes to winds and weather.
