History

edit

Agate was the first test of the jewel designation series running from 1961 until 1966. Minor and major incidents occurred during these experiments, the most important being the Béryl incident on May 1, 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!. The French Defence Minister Pierre Messmer and other officials and civilians were present in the command post and were contaminated too (around >200 mSv).
