The National Academy of Sciences (NAS) Report “An Assessment of Illness in U.S. Government Employees and Their Families at Overseas Embassies” commissioned by the US State Department was released  by a committee of 19 experts citing “directed, pulsed radiofrequency energy” as “the most plausible mechanism” to explain the mystery illness suffered by  U.S. Embassy personnel. The New York Times describes how the report “provides the most definitive explanation yet of the illness that struck scores of government employees, first at the U.S. Embassy in Havana in 2016, and then in China and other countries. Many of the officers suffered from dizziness, fatigue, headaches, and loss of hearing, memory and balance, and some were forced into permanent retirement.”

The NAS report states that “overall, directed pulsed RF (radio frequency) energy, especially in those with the distinct early manifestations, appears to be the most plausible mechanism in explaining these cases among those that the committee considered.”

Although the  committee stated they “cannot rule out other possible mechanisms and considers it likely that a multiplicity of factors explains some cases and the differences between others” the committee found the symptoms to be consistent with effects from radiofrequency radiation.

“The committee found the unusual presentation of acute, directional or location-specific early phase signs, symptoms and observations reported by DOS employees to be consistent with the effects of directed, pulsed radio frequency (RF) energy. Many of the chronic, nonspecific symptoms are also consistent with known RF effects, such as dizziness, headache, fatigue, nausea, anxiety, cognitive deficits, and memory loss. Patient clinical heterogeneity could be due to variability of exposure dosage conditions, differences in interpretation of non-physiological vestibular stimuli, and anatomical differences that could influence individual exposure and/or response.”

Several cases “began with the sudden onset of a loud noise, perceived to have directional features, and accompanied by pain in one or both ears or across a broad region of the head, and in some cases, a sensation of head pressure or vibration, dizziness, followed in some cases by tinnitus, visual problems, vertigo, and cognitive difficulties. Other personnel attached to the U.S. Consulate in Guangzhou, China, reported similar symptoms and signs to varying degrees, beginning in the following year. As of June 2020, many of these personnel continue to suffer from these and/or other health problems. Multiple hypotheses and mechanisms have been proposed to explain these clinical cases, but evidence has been lacking, no hypothesis has been proven, and the circumstances remain unclear.”

The Report made several recommendations including: 

  •  The Department of State should expand its collection of baseline and longitudinal data and biological specimens from all personnel prior to and during overseas assignments.
  • If research or assessments support the possibility of radio frequency (RF) energy as a cause of illness experienced by some of its employees, the Department of State should train and equip employees with the capability to measure and characterize their exposure to RF energy in real time should the need arise in the future.

The Report documented decades of research finding the same symptoms. 

“There was significant research in Russia/USSR into the effects of pulsed, rather than continuous wave (CW) RF exposures because the reactions to pulsed and CW RF energy at equal time-averaged intensities yielded substantially different results (Pakhomov and Murphy, 2000). According to Pakhomov and Murphy, the Russian-language studies “indicated that pulsing may be an important (or even the most important) factor that determines the biological effects of low-intensity RF emissions” (Pakhomov and Murphy, 2000, p. 2). Military personnel (in Eurasian communist countries) exposed to non-thermal microwave radiation were said to have experienced headache, fatigue, dizziness, irritability, sleeplessness, depression, anxiety, forgetfulness, and lack of concentration, as well as internal sound perception for frequencies between 2.05-2.50 GHz (Adams and Williams, 1976). The review by Pakhomov and Murphy noted that many of the studies from the former Soviet Union were flawed in one or more ways, but that some were well done, replicated, and credible.”

In 2017, U.S. State Department officials contended that Cuba staged a sonic or some sort of attack on employees of the American embassy, causing a variety of neurological symptoms which include cognitive difficulties and problems with balance, eye tracking, sleep disturbances and headache.

 2018 publication in JAMA The Journal of the American Medical Association  authored by the team of doctors at the University of Pennsylvania who examined 21 of the U.S. government (Cuba)employees found the patients had suffered from concussion like symptoms—but without any blunt trauma to the head. The Associated Press reported that MRI scans showed damage to white matter in the brains of embassy employees.

According to a 2020 publication “Distinctive Convergence Eye Movements in an Acquired Neurosensory Dysfunction” published in Front. Neurol., 16 June 2020 | https://doi.org/10.3389/fneur.2020.00469 in “late 2016, diplomats in Havana, Cuba, began presenting with a unique symptom complex after perceiving a strange noise and/or feeling a pressure field in their domicile. This report is a retrospective, quantitative analysis of video-oculography data of pupillary light reflex performance and binocular disparity-driven eye and pupil movements during the acute time period after the reported exposure. The patterns of response in these 19 individuals are markedly different than those seen in a group of individuals with the usual acute mild traumatic brain injury (17 subjects) and from 62 control subjects (21–60 years old) with no injury. Complaints of sudden-onset tinnitus, ear pain, and dizziness emerged in late 2016 to early 2017 among diplomatic personnel and their families in Havana, Cuba. These affected individuals often reported hearing a loud, high-frequency, localized sound, and were under the impression that it could follow them in a room.”


During the Cold War, the Russians bombarded the US embassy in Moscow with radiofrequency (microwave) radiation for several hours a day from the 1950s until 1979. The US government never confirmed the reason for the irradiation though there were several theories.  One was for covert audio surveillance of the embassy.  The wireless listening devices employed by the Russians were passive, and they were only activated in the presence of radiofrequency electromagnetic fields.  “The Thing” was the first such listening device discovered in the Ambassador’s office of the US embassy.   Other theories were for interference with American electronic‐intelligence equipment or for affecting the health or behavior of the employees at the embassy.  The irradiation exposed up to 3500 employees and dependents at the US embassy during this time, and it was kept secret from the embassy employees until 1976.

“Radiofrequency (RF) Sickness in the Lilienfeld Study: An Effect of Modulated Microwaves?”  published in Environmental Health concluded there were 4 statistically significant effects seen in exposed employees:

  1. dermographism (eczema, inflammatory and allergic skin problems)
  2. neurological
  3. reproductive
  4. tumors

Ambassador Walter Stoessel, who served at the US embassy in Moscow during the time it was irradiated and who died of leukemia at age 66, wrote a memo in 1976 that the radiation levels measured at the embassy, 1-15uW/cm2, is many times higher than background levels of cities and that their medical experts say prolonged exposure at the levels at the embassy is a potential health hazard.  The memo was classified until 2006 and released by wikileaks.  The radiation levels measured were lower than the current US government exposure guideline, which is the FCC maximum permissible exposure limit of 1000uW/cm2 for 30 minutes at frequencies 1.5-100 GHz.

  • A mystery illness striking U.S. and Canadian diplomats to Cuba (and now China) “has confounded the FBI, the State Department and US intelligence agencies” (Lederman, Weissenstein, & Lee, 2017). Sonic explanations for the so-called health attacks have long dominated media reports, propelled by peculiar sounds heard and auditory symptoms experienced. Sonic mediation was justly rejected by experts. We assessed whether pulsed radiofrequency/microwave radiation (RF/MW) exposure can accommodate reported facts in diplomats, including unusual ones.
  • Reported facts appear consistent with RF/MW as the source of injury in diplomats in Cuba. Nondiplomats citing symptoms from RF/MW, often with an inciting pulsed-RF/MW exposure, report compatible health conditions.
