Havana Syndrome — Microwave Weapons : Project PANDORA – BIZARRE [2020]

“The test protocol involved training the monkeys to press certain levers in response to signals. If the monkeys pressed the lever correctly, they would receive a reward of food, ‘much as embassy employees might be rewarded with a dry martini at the end of the day,’ wrote the columnist Jack Anderson. Researchers would then measure whether the monkeys performed worse when subjected to the Moscow Signal, compared with when there was no radiation.”

“There is no question that penetration of the central nervous system has been achieved, either directly or indirectly into that portion of the brain concerned with the changes in the work functions and the effects observed.”

In 1965, after the discovery that the American Embassy in Moscow was irradiated with microwave signals, the White House directed the State Department, the CIA and the DOD to attempt to determine the effects of such signals on human behavior.

The following report — dated December 20 1966 — documents the initials results of PROJECT PANDORA-BIZARRE.

I encourage the reader to pay close attention to the conclusions [V. IMPLICATIONS] of this report.

For the record — The expression “Havana Syndrome” was coined by Dr. Ludwig De Braeckeleer and appeared for the first time in a story published by the Intel Today blog on October 3 2017. [Here is the tweet]

SUBJECT: Project PANDORA – Initial Test Results 20 December 1966

Reference: PANDORA-BIZARRE Test Results – Memo dated 15 Dec 66


For more than five years, the American Embassy in Moscow has been radiated with low-level electromagnetic signals (the Moscow Signal) on a more or less daily basis for several hours a day. These signals, in the “S” and “L” band spectrum, have been in part recorded and are of complex modulation with a pattern of variation, some of which seems to be random.

The White House has directed, through USIB, that intensive investigative research be conducted within the State Department, CIA and DOD to attempt to determine what the threat is. The National Program has been coordinated by the State Department, under code name, “TUMS”. ARPA is represented and is conducting research on a selective portion of the overall program concerned with one of the potential threats, that of the effects of low-level electromagnetic radiation on man. This memorandum summarizes the initial test results obtained from this program called PANDORA.


The most important results obtained to date, after 28 days (not continuous) of radiation of a primate at 5 milliwatts/cm2 with a simulated Moscow Signal, have been two repetitive, complete slowdowns and stoppages of the monkey in carrying out his test work functions. The monkey normally works 10 hrs/day, 7 days week. At stoppage, the data strongly
suggests the monkey went into deep sleep. The second breakdown occurred sooner than the first, suggesting that pre-stressing due to the radiation environment had occurred. There is no question that penetration of the central nervous system has been achieved, either directly or indirectly into that portion of the brain concerned with the changes in the work functions and the effects observed.

Events leading to these breakdowns were as follows: On the 12th day of radiation (10 hrs/day), a definite slowdown was recorded in the monkey’s ability to time his work functions. On the 13th day of radiation, the monkey further degraded and finally stopped working. For the next two days of radiation, the monkey’s condition remained unchanged complete stoppage – at which time the radiation was terminated, Three days later (without radiation) the monkey returned to normal operation in his work functions. For five additional days (without radiation) the monkey maintained a normal work pattern. Radiation was turned on after this period and after eight days of radiation slowdown in work functions was again recorded, On the 10th day of radiation, complete stoppage occurred. The stoppage continued for the next three days at which time radiation was terminated. The next two days of recordings, up to 15 December 1966, reveal the monkey had not returned to normal.

At all times when the monkey ceased to respond, the measured deep core temperature dropped 1.2 to 1.5°F from normal with a delay of 30 to 60 minutes. It stayed at this level for the remainder of the 10 hr/ day. This data and direct observations on a TV monitor strongly suggest the monkey was in deep sleep. Detailed results of tests contained in Ref 1.


Only one monkey has, so far, been tested. It cannot be stressed too strongly that, at this time, conclusions as to what may generally be expected cannot be drawn until at least another monkey has been subjected to the same sequence of radiation and normal environments, and has shown similar effects.


A. Repeat test on second monkey which will be instrumented to detect various body changes.

B. Based on these results, a new design of tests will be constructed to determine the gross mechanisms involved in producing the effect observed.


The central nervous system of one monkey has been affected by low-level microwave radiation. If tests on another monkey display similar results then:

1. Attention must be given to initiating a National Program to investigate thoroughly these effects, since only isolated investigations have heretofore been carried on in the U.S. By contrast, the USSR has had an intensive national program in this area for more than 10 years.

2. The U.S. microwave radiation safety standards should be examined and overhauled to take account of the non-thermal damage potential.

3. The potential of exerting a degree of control on human behavior by low-level microwave radiation must be carefully investigated.
