A description of thermal radiation measuring instrumentation installed at Site 400, Mercury, Nevada, and the results of data obtained for Shots 6, 7, and 8 of Operation SNAPPER are contained herein. Calibration procedures are summarized and certain instrumentation difficulties are discussed. Measurements of spectral irradiation, transient irradiancy and total irradiation per unit area are presented. The results of the spectral irradiation data, which are of qualitative value only, suggest that at peak irradiancy from the fireball, the distribution of energy is similar to that of the sun under specified conditions. Transient irradiancy results for all three shots are normalized and plotted so that a single characteristic curve is defined.
