With the development of radiation measurement technology, the precision of radiation measuring apparatus is paid more and more attention, moreover, the correct calibration for apparatus is the important guarantee to improve the precision of radiation measurement. The methods that implemented absolute radiation calibration for the sky-light radiation luminance measurement system by transfering spectral radiometer and wavelength calibration by mercury-arc lamp were introduced in detail. TKFS01 sky-light radiation luminance measurement system was calibrated by the methods and the uncertainty of calibration was given. The system was applied to measure sky-light radiation luminance in practice. The data acquired by the calibrated system was analyzed. Compared with the results by MODTRAN 3 software, they were coincident very much. It shows that the methods are valid and feasible, which can be applied to the actual calibration for radiation measurement system.
