'Agathe' (aka 'Agate') was the name of the first
French nuclear underground test. It was an atomic bomb detonated in the Hoggar mount (near In Ekker) of the then French
Sahara desert on
November 21,
1961, during the
Algerian War (1954-62)
[1].
Agathe was the first test of the jewel designation series running from 1961 until 1966. Minor and major incidents occurred during these experimentations, the most important being the
Beryl incident on May 1st 1962 where the nine militarymen of the ''621ème Groupe d'Armes Spéciales'' unit were heavily contaminated (600 mSv) as portrayed in the 2006 docudrama
Vive La Bombe!.
[2] The French Defence Minister
Pierre Messmer and other officials and civilians were present in the command post and were contaminated too (around >200 mSv).
