This radiation implosion is much more effective than the high-explosive implosion of the primary.

In engineering terms, radiation implosion allows for the exploitation of several known features of nuclear bomb materials which heretofore had eluded practical application.

He opposed two-stage thermonuclear bombs until 1951, when radiation implosion, which he called "technically sweet", first made them practical.

Some Chinese documents showed that Chinese scientists used a different method to make radiation implosion.

While the results of this test were disappointing, the British learned much about radiation implosion in H-bombs.

The idea, known as radiation implosion, was to build a large cylindrical casing that would hold the atomic bomb and hydrogen fuel at opposite ends.

The energy released by the primary compresses the secondary through a process called "radiation implosion", at which point it is heated and undergoes nuclear fusion.

The design based on these ideas, called staged radiation implosion, has become the standard way to build thermonuclear weapons.

It also took just several months before the idea of radiation implosion was conceived, and there is no documented evidence claiming priority.

The main issue was radiation implosion and how to achieve it.
