Mostly, but there are always cases where this is not pratical. For example, the detectors at CERN (or any other particle accelerator probably) contain a lot of electronics (to capture and pre-filter the data) which cannot really be shielded (otherwise you don't have a detector anymore) or moved elsewhere (which would incur a lot of inconvenient delays and additional noise. Also, you don't wan't to lay a few meters of cables for every pixel ;)). Most of the computing power sits in an adjacent cave however where it is quite safe.
