Academic and Research Achievements: Chatterjee discovered the spontaneous fission of uranium simultaneously with and independently of Petrazhak and Flerov. He isolated 60Co chemically for the first time from inactive neutron-irradiated 59Co and extracted and purified He gas (99.98%) and other noble gases from natural gas emanating from thermal springs of India. He also fabricated B10F3-filled (at high pressure) ionization chamber and proportional counter and suggested possibilities of Mossbauer effect by cooling in liquid helium.

Other Contributions: Dr Chatterjee started the SD Chatterjee Research Foundation in Kolkata and was its Director (1985-95).
