He was fascinated by rationalist architecture and was one of the first Italian artists to break from figurative art to join the abstract movement flourishing across Europe at the time.
Radice worked closely with the most important Italian rationalist architects (Terragni, Lingeri, Sartoris and Cattaneo), reaching international popularity with abstract frescoes done between 1933 and 1936 for the famous Casa del Fascio of Como, a masterpiece municipal building by Giuseppe Terragni for the National Fascist Party.
Recently (2007) some of his works were included in two big exhibits held in Milan's Royal Palace: Camera con vista and Kandinskji and Italian abstract art.
Like the works of the other founder of the Italian abstractist school, Manlio Rho, Radice's art is recognizable for pure and harmonic geometric shapes in warm colors.
Radice's works can be found in the permanent collections of many modern art museums, including those of Milan, Trento, Rovereto, Turin and Rome.
