Can sometimes just be the valve vibrating, I wouldn't expect it to only vibrate when the boiler is off though.

Check the valves, if slightly closed try to remember where they're set to as the system has probably been balanced - try opening the radiator valves fully and see if the noise stops.

from your description i'd say it's in the rads themselves. try adding a cleanser. the only solution is flushing the system out or new rads.
