Tests are being carried out on soil, grass and animal bone samples from several representative areas in the United Kingdom of which four are in high ground. One area is in County Durham. The results published so far are available in two reports which are in the Library. I have received four letters specifically referring to the incidence of strontium 90 in Welsh mountains.
