Abstract
Results of measurements and processing of sizes, energy, and power of radiation of a cloud formed after an explosion of 50/50 TNT/RDX and TNT cast charges with masses ranging from 0.01 kg to 1000 tons on the ground surface and at different heights in air are presented; the measurements and data processing are performed within wide temporal (up to 10 s/kg1/3) and spectral (up to 28 m m) intervals. The results are compared with available published data. These explosives have the maximum radiative characteristics owing to the high content of carbon in explosion products. Under conditions of explosions in air, the measured emitted energy approaches 50% of the explosion energy. In the case of ground explosions, the radiation is anisotropic because of screening by ejected soil, and the ratio of energies emitted upward and along the ground surface can exceed the order of magnitude.
