Operation Emery
Encyclopedia
Operation Emery was a series of twelve nuclear tests conducted at the Nevada Test Site
. These explosions occurred in 1970 and 1971, after the Mandrel
series and before Grommet
.
The Baneberry blast was notable for the 6.7 million curie
s (250 petabecquerel
s) of radioactive material that escaped through unanticipated cracks in the ground. A six month moratorium was placed on the US nuclear testing program.
The individual tests of this series were:

Operation Mandrel
Operation Mandrel was a series of 53 nuclear test explosions conducted in 1969 and 1970. This test series included a 1.2 megaton "calibration shot" code-named Milrow, which was detonated underground at Amchitka Island, Alaska, and the 40 kiloton gas stimulation experiment code-named Rulison,...

Operation Grommet
Operation Grommet was a series of 34 nuclear tests conducted at the Nevada Test Site in 1971 and 1972 including one in Alaska in 1971. These tests followed the Emery series and preceded Toggle....

Curie
The curie is a unit of radioactivity, defined asThis is roughly the activity of 1 gram of the radium isotope 226Ra, a substance studied by the pioneers of radiology, Marie and Pierre Curie, for whom the unit was named. In addition to the curie, activity can be measured using an SI derived unit,...

Becquerel
The becquerel is the SI-derived unit of radioactivity. One Bq is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. The Bq unit is therefore equivalent to an inverse second, s−1...
