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.

space application human effects [22,23]. In these experiments low energy proton
effects on tissue were observed.viii In these experiments, incident energies were
selected for skin surfaces that were very similar to the example of the RF/ NIEMR 30 -
300 GHz millimeter wave experiments just described: 1-30 Mev.
The ranges of skin penetration were the same: 0.5 - about 5.0 mm. At the highest
doses selected (up to 2000 rads) no clinical effects were noted at or below equivalent
Mev - levels found at millimeter waves, SARs of 10 mW/cm 2 .
There have been several studies {encompassing about 100 reported cases during acute
accidental exposures in military aerospace and communications situations} that have
collected data on human exposures to RF of mixed and broad bandwidths [ 1,23].
Comparison of this medical literature presents striking overlaps to the claimed clinical
injury patterns of several hundred near-field cases of anomalous and hostile events
being currently analyzed for a compan ion study to this, as described in Appendices A,
B, & C.
The emergent findings are that in nearly all cases in which exposures are of the order of
minutes or longer, including visible indications at distances of 10 meters, similar acute
effects are observed. In order of their positive and negative clinical presentation the
signs and symptoms [23,24,25,26] include:
• Warming/prickly sensation over exposed glabrous skin
• Sensation of burning, no itching or small myelenation injury
• Erythema, which progresses top 2nd -degree burns in 72 hours
• Headache, temporal: effect lasting three weeks
• Dizziness/vertigo, o~en with nausea/ vomiting at 24- 72 hours
• Cardiac palpitations at 48-72 hours
• Neurasthenia and peripheral neuropathy absent fasciculation
• Absent evidence of neuromuscular small fiber disease
• Absent evidence of alpha-motor neuron involvement
• Malaise and low-grade fever, emotional liability
• Severe anxiety with high exposure over 10 or greater minutes1x
• Corneal abrasion due to deoxygenating, "gritty eye syndrome"
• Scleral inflammation and iriditiis, photophobia
viii Spaceflight and possible weapons applications were of great concern, and sources indicate, that there was
concern of reported UFO/Anomalous effects at the time [24)).
ix "Severe Anxiety" as assessed clinically to require medication and hospitalization is a marker for broadband
RF/NIEMR [but not ionizing] radiation exposure greater than about 500 mW/cm or Sx10 W/m Thus, a2 3

neurological examination that can separate psychiatric from neuropath ic and small nerve fiber damage can serve to
demarcate exposure in SAR, and can help distinguish whole body, head, and/or hot-spot surface absorption .
