Yep, there is a way.  gtk_toggle_button_get_active() which returns a
gboolean I believe.  If it returns TRUE, then the button is pressed.  If
not, then it's not.  Note you have to cast the radio button to a toggle
button (which should work) inside.  LIke this

GtkWidget *radio_button = gtk_radio...etc..

if(gtk_toggle_button_get_active(GTK_TOGGLE_BUTTON(radio_button)))
{
	printf("It's pressed down.");
} else printf("It's not pressed down.");

Hope that helps.  Check out the toggle button functions in
/usr/include/gtk/gtktogglebutton.h - it will give you a whole bag of
goodies you can use with radio buttons
