Operation Hardtack. Project 8.5a. Narrow-Band Infrared Spectral Irradiance of High-Altitude Bursts
Abstract
The objective of this project was to obtain basic data in the infrared region of approximately 1.7 to 13 microns from high altitude nuclear detonations at an airborne station. More specifically, the objectives were to determine (1) the spectral distribution of the irradiance, particularly at late times on the order of a minute after detonation, and (2) the size and shape of the infrared fireball as a function of wavelength, in several spectral bands, and time. For correlation purposes, a megaton-range shot detonated at sea level was to be documented. Classified material has been removed in order to make the information available on an unclassified, open publication basis, to any interested parties. The effort to declassify this report has been accomplished specifically to support the Department of Defense Nuclear Test Personnel Review (NTPR) Program. The objective is to facilitate studies of the low levels of radiation received by some individuals during the atmospheric nuclear test program by making as much information as possible available to all interested parties.
