As a pre-show of Kein Licht's performances at EHESS, Karine Le Bail, the CNRS and PSL University organized an exhibition of two installations by Dominique Peysson - Trafic 3.0 and Etude de nuages - a cycle of mini-scientific conferences and citizen debates, and a performance, Life is a vapor... and then nothing by Dominique Peysson and Olivier Goulet.

"The avant-spectacles that precede the musical moment constitute a particular space-time where the audience is as much inhabited by desire and expectation as by questions to ask. So much so that this time is often nourished by an additional matter to think about the work in its historical, musical and philosophical context. »

This radioactive installation involves the circulation of drops of fluid in microscopic labyrinthine circuits the thickness of a hair. Their image is projected live by means of an optical system, without going digital. Each small drop that passes through the system is radioactive, but so small in size that the radiation is minute. But the projection system, made of concrete, reminds us of nuclear power plants crossed by highly radioactive fluids, particularly dangerous at these size scales. High radiation levels can then be responsible for cancer. Diseases that are often treated ... by radiotherapy, by circulating radioactive materials in our blood capillaries, as fine as our hair.

The public will be able to test the level of radioactivity at various points in the facility using a Geiger counter at their disposal, and feel the tension rise as the number of strokes per minute detected by the counter accelerates.

Radiopharmaceuticals called tracers incorporate an element with a radioactive nucleus into their formula. The tracer's radiation makes it possible to trace its path within the body without disturbing physical, chemical or biological behaviour. The tracer is chosen according to its ability to follow a metabolism or to help diagnose the functioning of an organ. These are elements that emit mainly gamma rays, a radiation that irradiates little and is penetrating enough to leave the body to be detected.

The accident scenario for the Fukushima power plant is that of the loss of electrical power supplies following the earthquake, followed by the loss of the heat sink and internal emergency power supplies following the tsunami. Without the possibility of cooling, the reactor cores and the spent fuel assemblies stored in the pools undergo a significant increase in temperature until they exceed critical values. The depressurizations undertaken afterwards to limit the pressure in the installation lead to the first releases of radioactive products into the environment. Fires followed by explosions will release massive quantities of gaseous radioactive effluents which will be followed by large masses of liquid radioactive effluents following the releases of water undertaken by the operator in an attempt to cool the installation.
