The positions of emission of berylliumlike oxygen ions in the core region as well as the hydrogen atoms in the boundary region of the limiter shadow have been measured by means of the difference of the Zeeman patterns in the spectral shape in the poloidal section of the TRIAM-1M super conducting tokamak [H. Zushi et al., Nucl. Fusion 43, 1600]. For determining magnetic field strength, the components of the Zeeman spectra are resolved by a linear polarizer. In addition to the emission region,
