Scientists have identified cancer clusters across Britain that can be traced to the presence of nuclear power stations along the coast.
The new nuclear reactor proposed at Hinkley Point has the potential, if there were any accident on the scale of Fukushima, to threaten the whole of south Wales.
For this reason, I joined Paul Relph from Cwmbran to take part in a weekend of demonstrations and actions.
There was a march and rally in Bridgwater, and a mass trespass on the building site at Hinkley C to plant wild flowers and reclaim the common land.
We blockaded the road to express our determination to stop this new reactor from being built.
We also trespassed on the proposed site and occupied it, scaling the high fence in spite of the army of private security guards and police.
I climbed over and tied a laminated photograph of my family on the fence - their future being the reason I was there.
I proudly displayed the Welsh flag, the dragon breathing flames of defiance, with a placard: "Wales says NO to new nuclear."
At 1pm we gathered in a huge circle in the middle of the proposed site. I was asked to lead the singing.
First for the many people who had come from all over Britain and abroad to show solidarity we sang "We shall overcome."
Then I led the singing of "Mae gen i freuddwyd" (I have a dream).
It was wet and cold - but we left knowing that we were right.
We took another step towards stopping the madness of further nuclear development, at a time when the rest of Europe are getting 60 per cent of their energy from renewables.
The campaign goes on.
