Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government what is the precise nature of the waste material to be removed from the construction site for the new Hinkley Point power station; what contaminants are expected to be found within that material; and whether they have evidence that that material might include irradiated material.

The material to be removed from the dredge site is sediment, consisting of clay, silt, sand and gravel. A range of chemical and radiological materials were tested for, which included gamma emitting radionuclides and chemicals. These tests, carried out by an accredited laboratory, showed that the levels of chemicals and radionuclides were within acceptable levels under international guidelines and considered to be safe.
