which allow determination of the incident thermal
radiation on a receiver in the vicinity of a nuclear
detonation. The equations are essentially curve fits to
the thermal energy values calculated by the Chapman and
Seavey prediction technique (AFCRC-TN-54-25) for both
ground and air bursts and for a variety of atmospheric
and geophysical parameters. The simplified equations
correlate very well with the thermal energy data
obtained during Operation Redwing. The thermal energy
equations for the specific type days standardized by the
Air Force in their nuclear weapons capabilities studies
are included in the report. Sample calculations
employing the simplified equations and a summary of the
pertinent equations are presented in appendixes. 5

ABSTRACT
Details of the design, calibration, and use of the
photoelectric log box detectors used to obtain air
fluorescence data are given. Descriptions of the High
Altitude Fluorescence (HAF) and High Altitude Resonance

presented. These sections are concerned mainly with
assumptions, derivations, and some program features of
the codes; no coding details are provided. The
procedures used to obtain absorption cross sections for
use in HARAC are described, including a discussion of
the assumptions and the approximation used “to account
for the rotational structure. The importance of some
neglected processes is discussed. Results of
calculations on specific events and their use in
analysis of the Dominic and Hardtack air fluorescences
data are given in the classified part of this report.
