This is really a tricky issue.
Why? Well, let's think of how the renderer happens before you have Radiosity. You have a lot of specularity, because you have a very well defined light source.
When you add Radiosity, what happens to the light? It bounces back and forth, and the light now will not come from a single light source, but instead it comes from "everywhere".
This will make your specular highlight fade and in some cases almost disappear in the scene.
The trick to solve it is to add "Specular-Only" light sources, so you can control specular highlights manually.
