Bananas, brazil nuts and some other foods contain radioactive potassium-40 — but in extremely low doses. Potassium-40 in bananas has a specific activity of 71 ten millionths of a curie per gram. Compare that to the 88 curies per gram for Cesium-137. This is like comparing a stick of dynamite to an atomic bomb. Our bodies manage the ingested Potassium 40, so that after eating bananas, the excess is quickly excreted and the body’s Potassium-40 level remains unchanged.

The radioactive isotopes that come from nuclear fission (such as strontium -90, cesium -137 and iodine 131) were unknown in nature before atomic fission: our bodies are not adapted to them. And as well as being far more radioactive that Potassium -40, they can accumulate in the body.

I had hoped for something sensible to come out of these Citizens’ Juries. That doesn’t look like happening if the juries continue to be fed this kind of nonsense. 

Chocolates, bananas, ionising radiation…
