"British Bang" on German Archipelago

Heligoland is a small German archipelago located in the North Sea that consists of two islands: the populated main island of Hauptinsel and the smaller island of Düne. Hauptinsel is commonly divided into three geographic sections, the last of which came into being in 1947, when the Royal Navy detonated 6,800 metric tons of explosives on the island, actually changing its shape. The "British Bang" was the biggest non-nuclear single detonation in history. Why did the British bomb the island?



Radiocarbon Dating

Radiocarbon dating is a method for determining the age of carbonaceous materials—especially ancient archaeological specimens—that relies on the presence of a naturally occurring isotope called carbon-14. After an organism dies, the amount of carbon-14 in its remains gradually decreases through radioactive beta decay. Measuring the amount of carbon-14 in an organism's remains thus allows scientists to determine how long it has been dead. How do atomic bombs affect atmospheric carbon-14 levels?
