any radio signal coming out of a VOR station is defined as a Radial.
Now an example:
let's consider you are tracking a course of 90° TO the XXX vor ( CDI centered, OBS 090°), maintaining a heading of 090° (no wind); now in this case you are on radial 270°. After passing the vor you'll have an indication FROM and now you are on radial 090° (OBS still set at 090°).
To recap the meaning of Radial: RADIAL is always a Course FROM the VOR station.
Whatever your heading,whenever you say you are on radial eg. 180 XXX VOR: you are telling the controller you are South of XXX VOR.
Hope this can help
