What is concrete made out of? Rocks? What do rocks contain? Radioactive elements.
So that's not actually the best way to protect against radiation.
- frumiousirc 10y agoThe energy involved in radioactive decay is far less than that of cosmic rays. If the goal is to protect ICs from bit flips then indeed putting them under concrete or natural rock will reduce them.
- gnufx 10y agoYou don't have a background in nuclear spectroscopy, and I claim my £5. The irony of this: what is typically used for nuclear spectroscopy? Semiconductor detectors? If you get one out -- albeit probably a geranium^Wgermanium detector rather than silicon, if you do gamma rays -- potassium-40 products stand out in a typical environment. (I've mostly done that over sandstone -- why the lab was there; it may be different somewhere like Edinburgh.) Concentrated in a calibration source rather than a concrete block, it would be controlled.
