- I read up on RDS 220 and it seems to have been an absolute monster of a bomb, can you tell us more about it?
- What was the environmental impact of these nuclear bomb tests? Are areas that were bombed still affected? Any examples that stand out?
ROBERT KISS / Formal Method
- The ‘Tsar bomb’ (official designation AN602) was the single largest nuclear device ever exploded. Is was a pure demonstration of power, that the USSR was capable to produce very high yield assets, but its propaganda means were much more significant, than its practicality, hoewever it was deployed from a modified TU-95 bomber. Originally designed to up to 100 megatons, the actual test occured with the removal of the uranium-238 tamper, which would roughly half the yield to approx 58 megatons, what is still an unbelievable number…. The detonation occured on 30 October 1961 at Novaya Zemlya (an island north of the russian mainland, in the Barents sea), and it was so huge, that the carrier plane (then 115 kms away from ground zero) dropped a whole km in altitude when it was hit by the shockwave, what itself circulated three times the planet before fading out (also a seismic shockwave in the earths crust travelled 3 times around). The flash could be seen from 1000 kms away, and the blast shattered windows a mere 800 kms away from ground zero. The mushroom cloud reached an altitude of 67 kms, with a diameter of 95 kms. Despite this enourmus numbers, the device itself was one of the ‘cleanest’ in terms of fallout, as the vast majority of the explosion energy came from fusion, and as the uranium tamper was removed, radioactive material release was minimal.
-If you may hear some similarities in the track with the first one, in terms of sound and style, its a bit intentional as the tsar bomb was kind of the ultimate culmination of Teller’s dream, what became the symbol of the cold war and nuclear deterrence.
- Most of the tests were carried out at very remote locations (mostly in the Pacific, but the russians tested a lot deep inside todays Kazakhstan), so we barely know exactly the impact. Actually environmental issues already occured at the Trinity test, but at that time scientists knew very little to nothing about the aftermath of a nuclear explosion. As more and more tests were carried out, more and more diagnostic studies were made, to examine the consequences. As these tests were mostly secret operations, little knowledge was given out about the results, including contamination, fallout and environmental impact. Later a lot of documents were declassified, so today we know much more about this, but we also have to know, that not only the tests resulted in contamination of their environments, but there was a significant industry made up to support these projects, where there were also a buch of incidents and accidents, what are quite high measured on the international scale of nuclear accidents. For example Three Mile Island/US, Windscale/UK, Mayak/USSR. All of these caused significant contamination around, not to mention the people who were injured. Byproducts can still be found in the soil, the waters and the atmosphere I think, however most nuclear byproducts ‘live’ very short as we know, but some of them can be dangerous even after a long time.
