Thank you for your comment. I was also a bit startled when I plugged in the scale bar, so I guess the easiest way is to adjust the scale. The blobbiness of the coastline is due to looking at part of the map. I'd love to change it but not quite sure how I would do that at this point. I'll just have to make sure in future that a coastline should look good at any zoom level.

I tried to add the dark outline of the coast and a white halo on the scale. I did fiddle with the brightness of the forest layer, but the radioactivity seems still to be there. I think it's a real improvement though, so thanks again.
