[edit] Summary
| Description |
English: Final height h and radius r of a nuclear mushroom cloud as a function of the explosive yield W. The final height is approximately the height above the burst point for low and intermediate W and approx. the height above sea leval for high W. Quelle: Glasstone & Dolan (1977), numerical approximation of original graph.
Deutsch: Endhöhe und Radius der Pilzwolke einer Kernwaffenexplosion als Funktion der Sprengkraft W. Die Endhöhe ist ungefähr die Höhe über dem Detonationspunkt für geringe und mittlere W und ungefähr die Höhe über Meeresniveau für große W. Quelle: Glasstone & Dolan (1977), numerische Näherung des Originalgraphen.
