Operation Dial Pack 1970 - Canadian project A7 thermal radiation measurements / by J.D.R. Pattman.: DR52-17/4-1971E-PDF
"Thermal radiation from the Dial Pack 500-ton TNT explosion was recorded in selected wavelength bands, using a high-speed bolometer system, photo-electric detectors, and calorimeters. The radiation was received in both broad and narrow spectral bands, defined by placing suitable combinations of glass filters and silica windows in front of the detectors. Results were obtained from all instruments used, and are presented in this report. These include measurements of the total thermal energy radiated, the thermal pulse shape as shown by records of irradiance versus time, and the variation of spectral distribution as a function of time. Estimation of the apparent temperature of the fireball surface is also discussed. Some comparisons are made with results from previous large TNT explosions.
