- * Nuclear Tests
We shall use the distinction between a nuclear test and a nuclear explosion
that was adopted in the revised protocol of 1990 for the Threshold Test
Thus, a single underground nuclear test (UNT) can consist of a
number of different underground nuclear explosions (UNEs) provided these are
carried out within a time interval not exceeding 0.1 s and within an area
delineated by a circle whose diameter is less than 2 km. Explosions with a
time interval longer than 0.1 s, or a distance greater than 2 km, are
counted as separate tests.
We note that this distinction between UNTs and
UNEs has been followed in official Russian documentation of the Soviet test
program at STS, but with one exception, namely the nuclear test which was
conducted at Degelen in a tunnel on January 30, 1974.
