Subject: SECRET Document Mentions Correlation Between
Sightings and Rise in Radiation, dated 27 Feb 1953
Cat: 10
Distribution: CE, SHG, NCP
In the summer of 1952 it was reported to Project Blue Book that in the
past several years there have been some instances where there existed a
supposed correlation between the visual sighting of unidentified object
and a rapid rise in radiation count on radiation detecting devices in
areas close to the Mt, Palomar Observatory, California, and later at
Los Alamos, New Mexico. In early fall of 1952 Project Blue Book began
to make inquiries about these occurrences. It was found that in October
1949 such an incident had occurred at the Mt. Palomar Observatory and
that the Navy had investigated. It was also learned that several times
during 1950, 1951, and 195? that same occurrence had taken place at the
Los Alamos Scientific Laboratory in Los Alamos, New Mexico. In regard to the Palomar incidents, the Navy flew several
aircraft over the area on Oct. 21 and Nov. 2, 1949, with different
types of radio, radio altimeter and radar equipment to see if anything
could trigger the geiger counters, but failed. There were 21 episodes
of the cosmic ray geiger
counters going off-scale over the next 10 days and then suddenly
stopping, without explanation.
