The measurement of THz radiation in the continuum present new technical challenges concerning materials, frequency filters and detection devices. We present the first results of a radiometric system using Golay cell as a detector, for the whole > 15 THz range, and at discrete frequencies centered at 2, 10 and 30 THz. The system was designed to measure solar THz radiation. It is capable to detect small solar bursts, with a large dynamic range to be able to detect larger events.
