Documents / Official release
This Defense Intelligence Reference Document, dated 11 March 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office under the Advanced Aerospace Weapon System Applications program. It reviews reported injuries to people exposed at close range to anomalous aerospace vehicles and attributes them mainly to electromagnetic radiation field effects, including burns, neurological and auditory effects. It argues that clinical diagnoses can help infer the characteristics of advanced systems. The appendices hold a case catalog and ICD code tables.
From the source:Release of 2026-09-18 Incident: 3/11/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD surveys reported acute and subacute injuries allegedly associated with close exposure to anomalous field effects, attempting to draw tentative parallels between these claimed symptoms and the known physiological effects of intense radiofrequency .and microwave exposure on human tissue. By reviewing medical and biophysical literature on heating, burns, neurological effects, and sensory disturbances, the report speculates on theoretical mechanisms by which intense electromagnetic fields might account for some of the reported injury patterns, though it does not establish a direct causal link between the reported injuries and any specific source. It hypothesizes that clinical symptoms and reported exposure circumstances might allow for highly constrained, limited inferences regarding the characteristics of an unknown emitter or propulsion system. Notably, the document’s findings rely heavily on case comparisons lacking physical examinations, untestable exposure conditions, and a mix of established science and more controversial literature. These comparisons are then extended to anomalous-craft scenarios, attempting to map known electromagnetic injury mechanisms onto anomalous encounter claims that lack independent scientific validation in the report.

evaluation are based generally on criteria published by the Institute of Electrical and
Electronics Engineers, Inc., {IEEE) for localized specific absorption rate ("SAR") in
Section 4.2 of "IEEE Standard for Safety Levels with Respect to Human Exposure to
Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz," ANSI/IEEE C95.l-1992.
These criteria for SAR evaluation are similar to those recommended by the National
Council on Rad iation Protection and Measurements (NCRP) xiv .
(1) FCC Limits for Occupational/Controlled Exposure: 0.4 W/kg as averaged over the
whole-body and spatial peak SAR not exceeding 8 W/kg as averaged over any 1 gram
of tissue {defined as a tissue volume in the shape of a cube}. Exceptions are the
hands, wrists, feet and ankles where the spatial peak SAR shall not exceed 20 W/kg, as
averaged over any 10 grams of tissue.
(2) FCC Limits for General Population/Uncontrolled Exposure: 0.08 W/kg as averaged
over the whole-body and spatial peak SAR not exceeding 1.6 W/kg as averaged over
any 1 gram of tissue. Exceptions are the hands, wrists, feet and ankles where the
spatial peak SAR shall not exceed 4 W/kg, as averaged over any 10 grams of tissue
( defined as a tissue volume in the shape of a cube) [37].
These, then, are the current {highly summarized} internationally accepted scientific
standards for acceptance of the levels for acute injury, incorporating the "heating"
criteria of acute injury for ELF through MHz bandwidths. In one sentence: acute injury
of early burning is not likely to occur at any bandwidth in narrow or mixed frequencies
below about 1.0 W/kg or 1.0 mW/cm 2 at the low end, over minutes, incident to the
human body in the near-field (feet to yards).
Although low-level and chronic effects are not of special interest to us, a recent review
by the American Cancer Society specifies the bandwidths of ELF/ RF/ Therma l / and
Noise effects from "Fields" of interest [38].
Of somewhat greater interest is the SAR versus frequency characteristics from which
one can adduce the injuries described in the preface to three antenna engineers, the
Cash-Landrum trio, and other cases. {Table Two, [1 p.281]}
Exposure of fibroblasts {cells used as sentinel cells in studies of RF and ionizi ng
radiation damage} to UHF Fields {849 MHz}, at high SAR levels {e.g. 10 W/kg, 1 hr}
do not result in any detectable damage. This includes endpoints of cell motility and
viability, cell cycle, cell distribution, cellular invasiveness, or cell migration. These
results hold even when exposures are extended to one hour per day for three days.
[39] Thus, in the Cash-Landrum case...one must assume that the RF and tissue heating,
clearly responsible for the erythema and burns, did not cause the cell dyscrasia and
subsequent gastrointestinal and malignant transformations; one assumes the cells DNA
damage was secondary to ionizing radiation [4,40].
