This work presents to our knowledge the first completely passive imaging of human body radiation below 1 THz at the room temperature without additional illumination or cooling. The successful image shows an impressive sensitivity limit of a terahertz FET detector (TeraFET). We made a 2.7 cm x 4 cm size image of a hand with a spatial resolution of 1 mm and a scanning speed equal to 1 cm^2 /100 s. The SNR is only 2.5 dB and the NETD of the hand radiation at room temperature is 4.8 K.
