2 Fission bomb radiation source. 3 Radiation transport. ... Radiation implosion is the compression of a target by the use of high levels of electromagnetic radiation.
The 3026-C was designed for work with sources between 1 and 10 Ci (37 and 370 GBq), but conditions forced it to be adapted to work with 100 Ci (3.7 TBq) sources. Its capacity was insufficient as demand grew. In May 1945 a dedicated building 3026-D (706-D), adjacent to 3026-C and designed to process sources up to 1000 Ci, was completed.
Some sources have suggested that Ulam initially proposed compressing the secondary through the shock waves generated by the primary and that it was Teller who then realized that the radiation from the primary would be able to accomplish the task (hence "radiation implosion"). However, compression alone would not have been enough and the other ...
More than seventy years after the test, residual radiation at the site was about ten times higher than normal background radiation in the area. The amount of radioactive exposure received during a one-hour visit to the site is about half of the total radiation exposure which a U.S. adult receives on an average day from natural and medical sources.
A similar case occurred in 2000 in Samut Prakan, Thailand when the radiation source of an expired teletherapy unit was sold unregistered, and stored in an unguarded car park from which it was stolen. [134] Other cases occurred at Yanango, Peru where a radiography source was lost, and Gilan, Iran where a radiography source harmed a welder. [135]
At a minimum, this implies a primary section that consists of an implosion-type fission bomb (a "trigger"), and a secondary section that consists of fusion fuel. The energy released by the primary compresses the secondary through the process of radiation implosion, at which point it is heated and undergoes nuclear fusion.

The design breakthrough came in January 1951, when Edward Teller and Stanislaw Ulam invented radiation implosion – for nearly three decades known publicly only as the Teller-Ulam H-bomb secret. [26] [27] The concept of radiation implosion was first tested on May 9, 1951, in the George shot of Operation Greenhouse, Eniwetok
