abstract="If the tectonic strain theory for luminous phenomena be correct, then significant electromagnetic emissions and radon gas release should occur in focal regions in which people report an alleged &quot;UFO flap.&quot; Considering the epidemiological evidence that these stimuli might promote the incidence of brain tumors, their occurrence during the 5 years before and the 5 years after the November, 1975 episode of multiple luminous displays within the Sudbury Basin (Canada) was examined. Compared to the adjacent control area, there was a significant increase in brain tumors after the episode for men (conservative odds ratio = 2.5) but not for women; however, the magnitude was well within the expected range of incidence within the general population. Such changes have theoretical implication but may have little clinical or health significance.<p /> <p>Language: en</p>",
