There were 204 of them. An accident that was passed off as an unannounced nuclear test.”In “Alien Contact” Lazar said in a March, 1990 interview, the blast occurred in May of 1987 in a vertical tunnel, and took out the first door, killing 3 people. After all, that’s what Lazar said this incident was passed off as. Some sort of ionizing radiation is needed. 2). As the story goes, this unlucky fellow, along with a few others, were done in when they attempted to cut into an operating reactor that had been removed from one of the discs.Lazar says he was told this had occurred in an underground shaft or tunnel at the Test Site where the reactor had been taken for this particular “experiment”.In George Knapp’s KLAS-TV special when he first identified Lazar in November of 1989, Knapp stated (it is assumed with Lazar’s concurrence) “There was an accident he says, back in April 1987. Example of watercooled thermoelectric cloud chamber Just above the cold condenser plate there is a volume of the chamber which is sensitive to ionization tracks. It certainly wouldn’t have been expected.On December 7, 1993, as part of its new openness, the DOE released a listing of ALL previously unannounced tests at the Test Site, going back to 1963. Cloud chamber with cloud tracks created by particles of Alpha particles from a Radium source in a cloud chamber One of the major elements of Lazar’s story, and one he’s repeated several times, is that he was told he was hired as a “replacement” for another scientist that had been killed in a major explosion. "Cloud Chamber" redirects here. The large CLOUD experiment at CERN today also uses a cloud chamber, to investigate the effects of cosmic rays on cloud formation. The inconsistency of the dates, while not desirable, is probably not unreasonable given Lazar’s memory.So what do the Test Site records have to say about this?Per DOE records, there were three announced tests in April, 1987:These tests were definitely known in advance as there was the usual contingent of protesters at the Test Site gate.There were no announced tests in May of 1987 according to the DOE. Though the cloud chambers at CERN each took many years to plan and build, you can make your own cosmic-ray detector in the classroom providing you have access to the right materials. The hot-water tank is an aluminium tank with a capacity of 200mL, and the observation cham - ber is a plastic vessel (80 × 80 × 95mm) whose Figure 2. George (as an investigative reporter with 28 Emmy’s for excellence in journalism - and counting), personally saw Bob’s “cloud chamber experiment” with a handful of others. A cloud chamber, also known as a Wilson cloud chamber, is a particle detector used for visualizing the passage of ionizing radiation. The ion trail left by the radioactive particles provides an optimal trigger for condensation and cloud formation. One of the major elements of Lazar’s story, and one he’s repeated several times, is that he was told he was hired as a “replacement” for another scientist that had been killed in a major explosion. What about unannounced tests? It requires a source of liquid alcohol at the warm side of the chamber where the liquid evaporates, forming a vapor that cools as it falls through the gas and condenses on the cold bottom plate. Alpha particles and electrons (deflected by a magnetic field) from a thorium rod in a cloud chamber Cloudylabs cloud chamber working approx 50 min [720p] - YouTube Th-th-th-that’s all, folks….So, there were no unannounced nuclear tests that support Lazar’s story, and the announced tests were known in advance so they don’t make sense as an explanation.As one final check, what do the seismic records of the US Geological Survey show?CAT YEAR MO DA ORIG TIME LAT LON DEP MAGNITUDE IEFMDTSVNWG DISTPDE 1987 04 18 134000.60 37.25 -116.51 0 5.5 mb GS ……E.. 35PDE 1987 04 22 220000.09 36.98 -116.00 0 4.2 mb GS …..E.. 21PDE 1987 04 30 133000.09 37.23 -116.42 0 5.5 mb GS ……E.. 30If I might interpret the output for the reader, it indicates the only seismic activity within a 100 kilometer radius of the Test site for the months of April and May of 1987 were the three aforementioned underground tests.
