<p>The United States's Emery nuclear test series was a group of 16 <a href="/facts/Nuclear_weapons_test/s2srGDFP">nuclear weapons tests</a> conducted in 1970 and 1971. These tests followed the <i><a href="/facts/Operation_Mandrel/dWgISegW">Operation Mandrel</a></i> series and preceded the <i><a href="/facts/Operation_Grommet/Nzz1CKIf">Operation Grommet</a></i> series. </p><p>The underground Baneberry test vented into the atmosphere.
