Spectroscopic and bolometric measurements wi1.h spatial artd temporal resolutionshow that large radiation loss brings about the decrease in electron and ion tempera-lure and plasma energy. Regarding emissivity in a core plasma, the result bybolometric measurements well agrees with that estimated from impurity abundanceand radiative cooling rates. Carbon limiters have an effect to suppress the radiationloss for Ohmic plasma, but is insufficient for ICRF heated plasma. The main contribu-tion to radiation loss may be attributed to Fe impurity released from the ICRF anten-nae, the Faraday shield and vacuum vessel. By making carbonization, the Fe impurityis suppressed to a low level (n../w.?0.03%) and the radiation loss is reduced to P.../(P..-FP.,)?2O%. This clearly supported by the observation of Z..
