We report the plasma radiation loss power and impurity line emissions in the toroidal pinch experiment RX, TPE-RX under various plasma current (I-p) conditions. The emissivity at the off-axis chords is stronger than that at the central chord, and the plasma radiation profile is hollow. These trends are clearer at higher I-p. Although the plasma density increases with I-p, the radiation fraction remains constant at approximately 15% in the range of I-p studied. The input power increases with I-p. However, the increment cannot be explained entirely by the increment of the radiation loss power, which increases in proportion to the input power. At higher I-p, the emissions from impurities of both high and low atomic number (Z) increase. The increase of the line emission of these impurities reflects the increase of the plasma wall interaction.
