We debated the mud from outside Hinkley Point nuclear power station two weeks ago but we didn't get answers to some really serious questions. So, I want to pose again a question about the testing. In Kosovo, when mud was suspected of being radioactive, they tested using alpha spectrometry, gamma spectrometry and also plasma mass spectrometry. And yet, as to the mud that will be dumped not far from this building—and people 10 miles in-land will be breathing in particles from that mud; that's the scientific evidence that we've been given—why was it only tested using gamma spectrometry? And why on earth won't this Government direct Natural Resources Wales to retest the mud using the three methods that they use in other parts of the world when they suspect that mud is contaminated?
