If it's the radio then it would depend on the signal strength as well as the radio station themselves... I'd imagine radio stations would automatically attempt to normalise volume themselves but I'm definitely no expert in this field.

To be honest I wouldn't be too concerned- the only thing which would concern me if it was happening on CDs where you have control over the source and can compare it to other devices (e.g. trying the CD in another cd player).
