Had a much wider impact than just the immediate surrounding area. My uncle and cousin's sheep were just cleared from restrictions a few years back.

A week earlier, on 26 April 1986, reactor number four at the Chernobyl nuclear power plant in what was then the Soviet Socialist Republic of Ukraine exploded, sending a plume of radio- active particles – equivalent in toxicity to 400 Hiroshima bombs – more than seven kilometres up into the atmosphere and due east in the breeze. In the days that followed, as a fire raged unchecked inside the twisted, white-hot remains of the reactor, the wind direction reversed and the plume, now a kilometre tall, headed west towards north-western Europe. It wasn't until workers at a nuclear reactor in Finland detected abnormally high doses of radioactivity on their clothes - up to 100 times normal background levels – that anyone outside the Soviet Union realised the true severity of the accident.

On 2 May 1986, the plume finally passed over parts of the UK and, with fateful timing, so too did a column of cloud carrying heavy rain. The rain fell hardest where it always falls hardest – on the uplands. As the droplets of water fell from the sky, they carried with them the radionuclides – in particular, caesium-137, iodine-131 and strontium-90 – that had been dispersed from Chernobyl. It is estimated that 1% of the radiation released from the reactor fell on the UK. In an effort to prevent these radionuclides entering the food chain once they had settled on the upland soil, the ministry of agriculture, fisheries and food, as it was then known, ordered an immediate restriction on the movement and sale of sheep within the most affected areas – particularly north Wales, south-west Scotland, Northern Ireland and the Lake District, where the landscape is predominantly suited to grazing sheep. In total, almost 9,000 farms, and four million sheep, were placed under restriction.
