§ Mr. Hamiltonasked the Prime Minister to what extent there has been an increase of radioactivity over the United Kingdom 39W in the last month and how this increase compares with the increase in the same period in each of the last two years.
§ The Prime MinisterWith regard to the first part of the Question, I have nothing to add to the reply I gave on Tuesday to the hon. Member for Newcastle-under-Lyme (Mr. Swingler).
With regard to the second part of the Question, such short term increases of activity of comparable magnitude have been observed before, but there is nothing to suggest that these increases occur at regular calendar intervals. I must make it clear that the levels of activity return to about the normal background values after a few weeks.
