SVORNOST – THE WORLD’S FIRST RADIUM MINE
Introduction
Few mines in the world have undergone such an unusual transformation as the Svornost Mine in Jáchymov.
When miners descended into its depths in the 16th century, they were primarily searching for silver. It was this silver that made Jáchymov one of the richest mining towns in Europe and the place from which the famous thalers originated.
No one at that time could have imagined that the mine would gain its true worldwide importance thanks to a material that miners had long considered more of an obstacle.
The dark pitchblende accompanying the silver ores was destined to change the history of science.
History
For centuries, pitchblende was merely one of the ores found beneath Jáchymov. Later, it became a source of uranium pigments used in glassmaking and ceramics.
Its true importance, however, became clear only at the end of the 19th century after the discovery of radioactivity.
It was Jáchymov pitchblende that provided the material used by Marie Curie-Skłodowska and Pierre Curie in their research into new radioactive elements. From a substance that had originally been waste from the processing of uranium ores, they succeeded in obtaining radium – one of the rarest and most sought-after elements of its time.
Jáchymov thus gained an entirely new role.
It was no longer only a town of silver and uranium. It became a source of radium for the scientific world.
At the beginning of the 20th century, local uranium ore was processed to obtain radium preparations, and Jáchymov became one of the most important places associated with this new field.
The Svornost Mine became the world’s first radium mine.
This was not because radium itself was mined there as a separate ore. Radium was obtained through the complex processing of uranium ores, especially pitchblende. But it was precisely this connection that made Jáchymov a unique place.
Until the First World War, Jáchymov was among the only sources of radium in the world.
Legacy
The story of the Svornost Mine demonstrates the extraordinary transformation of one mining site’s importance.
First, it gave the world silver that stood at the origin of the famous thalers. Later, it provided uranium ore that helped scientists understand radioactivity. Finally, it became the source of water that still serves the world’s first radon spa today.
Over five centuries, a single mine became part of three great stories – money, science, and medicine.
Svornost is exceptional not only because of its long history. It is exceptional because of how many times it was able to change its significance for the world.
