Why do my radiators make a crackling sound?

I recently bought a home and have yet to spend  a winter in it, so it is only just now that I turned on the heat and I'm a bit concerned - they make a crackling sound when they operate, does that mean they are malfunctioning and need to be replaced? I’m just concerned that it may be a fire risk, thanks.
