Pechblende (prologue)

Bringing together an assemblage of archival materials, photo documents, literature and found objects, Pechblende investigates concepts of scale, proximity and distance in relation to radioactivity and the body.
Centred on the mineral Pechblende (the German word for a type of uraninite), the work traces a history of scientific and photographic processes narrated through the interconnected sites of laboratory, archive, museum and mine. Highly radioactive and uranium rich, pitchblende was relentlessly mined in the Ore Mountains of the former German Democratic Republic between 1946 and 1989, ultimately facilitating nuclear armament in the USSR. Despite the toxicity of the mines, and the documented health threats to the miners who worked there, the landscape of the Ore Mountains is now under way to being transformed into a tranquil mountain vista, with few recognizable traces of the still-radiating industrial worksites.

Concerned with both the literal and the political invisibility of radioactivity, Kriemann worked with scientists at the American Museum of Natural History (New York), the National Archives (Washington) and the Museum of Natural History (Berlin) to produce various versions of an “autoradiograph”–a unique type of photograph that is the result of directly exposing light-sensitive paper to the pitchblende specimens. This cameraless exposure results in an indexical but highly abstract image, one that is haunted by impressions of the iconic nuclear mushroom cloud and its blinding light.

For Pechblende (prologue) Kriemann employs analog photographic methods, including autoradiography, combining them with archival material. Aiming to visualise what is invisible and yet acutely present: radioactivity.
