The electromagnetic energy incident on ground-based antennas on Johnston Island as a result of the five high-altitude nuclear bursts of the Fish Bowl series was measured in the frequency regions around 925, 3000, and 24,500 Mc by the radiometric techniques described in this report. The data, recorded in terms of antenna temperatures, are directly interpretable as physical temperatures of the thermally radiating regions and allow the deduction of the attenuation encountered by radio-frequency signals passing through the burst regions. The time history of the temperatures of the burst region for the three microwave frequencies of the radiometric measurement presented considerable insight into the physical processes occurring during the high-altitude events. Electron densities and recombination rates were deduced from the radiometric data.
