Radiation-:-Exchange-between-Surfaces

Two long parallel surfaces, each of emissivity 0.7 are at different temperatures and accordingly have radiation exchange between m. It is desired to reduce 75% of this radiant heat transfer by inserting thin parallel shields of equal emissivity 0.7 on both sides. What should be number of shields?
