Post #141. Putting a nice hand of bananas on the granite bench top would double the radiation. But I'd love to be there for the conversation.
Almost all granite is ~4% K2O. More pink means more potassium and more radiation but still less than the 'nanas.
Thorium in granite is quite rare but quite bad. I don't know anywhere in Australia that has granite with thorium in it.
I'm with M61A1. No radiation means no sterile bandages. No quarry means no concrete, drains, bridges and so on. I had a banana with breakfast so I'm probably radioactive too because I'm ~0.4% potassium by weight. Putting tin foil on my head won't even reflect the radiation back in. Bad for the people around me ... Probably....
On the upside, I am forced to watch ABC 22 all day so I haven't seen a political ad yet. Happy days.
