- thih9 5y agoI found no mention (cmd+f) of “concrete” or “concorde” there; I still don’t follow.
- Cerium 5y agoSometimes fly ash is added to concrete as a pozzolan. It is produced by burning coal and is slightly radioactive.
- david-gpu 5y agoThe Concorde cruised at higher altitude than most commercial planes, thus you had less protection from the atmosphere during the flight and received higher amounts radiation from cosmic rays. Then again it flew for a shorter duration, so I don't know which method of travel exposed you to higher accumulated radiation.
