Hot rocks

Reading this article in the Western Morning News this morning, reminds me of something my father, James Lovelock, told me once. Following his travels round various nuclear waste repositories with a Geiger counter, he found that the measurements of radioactivity he took while visiting places such as Sellafield were very similar to those he obtained from certain Cornish beaches.
Granite is a more radioactive rock than many others, but anti-nuclear campaigners, concerned about the dangers of radiation, have no more reason to be frightened of going on the beach at St.Ives than they have to be nervous of living next door to Hinckley Point. Let us hope they will be enthusiastic about this form of renewable energy, that relies on the heat generated beneath the surface of the earth.
