EM interference from the radiation.
- sp332 16y agoI don't think the radiation has had any effect on radio communications, has it? That just seems really unlikely.
- jarek 16y agoEver wondered why data cables are shielded?
- asharp 16y agoAs far as I can recall, most data cables arn't shielded. Audio cables usually are, however, to stop hum/etc. when travelling over long distances. To be more specific, if you have wire it will act like an antenna. It's usually a fairly poor antenna for most types of EM that you would find, however there are some things, ie. 50hz hum from mains power and its harmonics, that are powerful enough to induce a nontrivial amount of interference for analog applications. Most digital signals either don't care (because the interference is too weak), or don't care (because they are using twisted pairs and the signal cancels out overall) and hence they are usually unsheilded. Nuclear radiation can't, in normal circumstance, induce a signal into a wire.
- wtallis 16y agoEven a leaky reactor won't do much to the RF signal, but it can affect basically every other aspect of the electronics: http://en.wikipedia.org/wiki/Radiation_hardening http://en.wikipedia.org/wiki/Radiation_hardening
- asharp 16y agoIt doesn't effect radio communications. It does very nasty things to electronics though. Mostly because it can provide energy directly to the inside of, say, a transistor or the inside of a dram cell causing things to malfunction. It can also do interesting things to the silicon lattice itself, which is what typically causes complete failure of electronic devices in a high radiation environment.
- naz 16y agoYes. They tried to send in robots to observe and help the liquidators move debris at Chernobyl, but they didn't last very long. It isn't so much the radio signal as the electronics get damaged very easily by radiation.
