Documents / Report
This Defense Intelligence Reference Document was prepared by the Defense Intelligence Agency in March 2010 under its Advanced Aerospace Weapon System Applications (AAWSA) 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 and neurological effects. The document argues that clinical diagnoses could help infer the characteristics of such systems. Its appendices list historical cases and classify reported physiological effects using ICD codes and Vallee ratings.

non-thermal, effects, and so much of the current literature is of little relevance for this
review [37]. That said, the Standards of the FCC (Federal Communications
Commission), WHO (World Health Organization), and other relevant industrial hygiene
and safety organizations comprehend the effects {at the high end} of acute exposures.
From [37] we see some interesting comments {Table One}

NOTE: Occupational/controlled limits apply in situations in which persons are exposed
as a consequence of their employment, provided these persons are fully aware of the
potential for exposure and can exercise control over their exposure. Limits for
occupational/controlled exposure also apply in situations when an individual is transient
through a location where occupational/controlled limits apply provided he or she is
made aware of the potential for exposure. In the United States, the FCC enforces limits
for both occupational exposures in the workplace and public exposures. The exposure
limits are variable according to the frequency in megahertz and the duration of
exposure time {6 minutes for occupational and 30 minutes for public exposures}. Table
One shows exposure limits for occupational and uncontrolled public access to
radiofrequency radiation such as is emitted from AM, FM, television and wireless
sources through the air. As an example, 583 microwatts/cm2 (μW/cm 2 ) is the public
limit for the 875 MHz cell phone wireless frequency and 1000 μW/cm 2 is the limit for
PCS frequencies in the 1800 - 1950 MHz range averaged over 30 minutes.
That is: we understand well that for 6 minutes {the same order of magnitude for which
we are interested in and concerned about unintended effects} of anomalous near-field
exposures ... six minutes at the above levels constitute the point at which {from other
unquoted industrial hygiene definitions} for RF & NIEMR tissues heating of less than 0.5
degree C, locally to the dermis, will occur. Thus, when one hears reports that definitive
heating and even erythema and later second-degree burns are suffered, one can
reasonably infer these levels have been surpassed! [2,4, & Green, 2009 Technical
Study 10].
Also, in June, 2007, the WHO ELF (Extremely Low Frequency) Environmental Health
Criteria Monograph, EMF Program released its ELF Health Criteria Monograph. In the
report, they stated: "Acute biological effects have been established for exposure to ELF
electric and magnetic fields in the frequency range up to 100 kHz that may have
adverse consequences on health. The metric for measurement is specific absorption
rate (SAR) and is expressed in watts per kilogram of tissue."
The limit for absorption of radiofrequency radiation is limited to 1.6 W/kG within 1 gram
of human tissue. The SAR criteria to be used are specified below and apply for portable
devices transmitting in the frequency range from 100 kHz to 6 GHz. The limits used for
