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.
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 ...
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

Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War.It is a low-to-intermediate yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design.
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]
