Incident Calved

The incidental of Calved is the possible detection of a Nuclear test by an American satellite of detection of atomic tests, named Vela . This incident took place the September 22nd 1979.

Detection

The double flash, characteristic of an atmospheric nuclear explosion, was detected the September 22nd 1979 with 00:53 GMT by the satellite Vela 6911. These satellites have only one capacity of detection, and not of localization. This one was obtained thanks to the surveying recordings of buoys, which detected an explosion per same hour.

No natural phenomenon is known to generate the double flash. All the double-flashes detected before by Vela satellites were caused by confirmed nuclear tests. However, the detector of electromagnetic impulses of the satellite was except service, which does not make it possible to dismiss the assumption of a meteoric impact .

Planes of the US Air Force sent did not detect any trace of abnormal radioactivity. On the other hand, of the abnormally high rates of Iode 131 were raised in Australia in the weeks which followed.

Author

The possible nuclear test asserted forever by any country. It took place on the South-African territory , at one time when this country did not have the means yet of manufacturing a atomic bomb. One evoked the possibility of a nuclear collaboration between Israel and the South Africa, relating in particular to an exchange of Tritium against Uranium.

Sam Cohen, the American scientist who conceived the Bombe with neutrons estimates, in an article of David Mr. Bresnahan appeared in 1999, qu ' it acted of a test French of a weapon with neutrons in collaboration with the the United States.
