What if they were made of lead? Or do you need a thick layer of lead to shield from ionizing radiation?

- TeMPOraL 8y agoNanobots by definition have important/active parts with sizes on the scale of molecules. Doesn't matter what the molecules are exactly - if a radiation particle hits an atom and ionizes it, it's likely to break the molecule it's in and thus the mechanism. By break, I don't mean break apart - but a molecule that suddenly gains or loses charge in its structure starts interacting differently with other molecules. (Except it's how ionizing radiation damages DNA; cells implement error detection, error correction and self-destruction mechanisms to limit the spread of DNA damage. Unless we go the biotech route and make our first nanotech by repurposing viruses and bacteria, our nanobots are unlikely to be as resilient.)
- chupa-chups 8y agoYes, you do. Quite a lot of it actually when near a radiation source; not so much farther away, but to remove it, you'll obviously need to be real near. More here: http://lmgtfy.com/?q=ionizing+radiation+shielding http://lmgtfy.com/?q=ionizing+radiation+shielding
