The "Béryl incident" was a French nuclear test, conducted on May 1, 1962, during which nine soldiers of the 621st Groupe d'Armes Spéciales unit were heavily contaminated by radioactivity.The test took place at In Eker, Algeria, then a French department, and was designed as an underground shaft test. Due to improper sealing of the shaft, radioactive rock and dust were released into the atmosphere. The soldiers were exposed to as much as 600 mSv. As many as 100 additional personnel were exposed to lower levels of radiation, estimated at about 50 mSv, when the radioactive cloud produced by the blast passed over the command post, due to an unexpected change in wind direction. Among those exposed were several French government officials, including French Defense Minister Pierre Messmer and Gast

- Béryl est le nom de code du deuxième essai nucléaire souterrain de la France, qui a eu lieu le 1er mai 1962 à In Ecker, au nord de Tamanrasset, dans le Sahara algérien. Un accident nucléaire s'est produit lors de cet essai. En effet, tout était prévu pour que l'explosion soit confinée à l'intérieur de galeries creusées dans la montagne du Taourirt Tan Afella, mais un défaut de confinement a conduit à libérer des éléments radioactifs associés à des laves et des scories, ainsi qu'à des aérosols. Une centaine de personnes ont été exposées à une dose supérieure à 50 mSv, dont Pierre Messmer, alors ministre des Armées, et Gaston Palewski, ministre de la Recherche scientifique. (fr)
