The Gastein cure is essentially based on radon. What is this that anyway? First of all, it is a radioactive chemical element. Within the periodic table it has the symbol Rn and the atomic number 86. This context however accounts radon for being part of natural scientific order and system of thought. Accordingly, the world is composed of chemical elements, just as in Europe it was made of air, fire, water, earth (and eather) prior to european enlightement. As such, elements cannot be divided. They are at the heart and essence of the world. Additionally, radon is not just any element, it is a noble gas and as therefor it has no colour nor odor. Could we thus circumscribe Radon as pure? If yes, this raises the question how natural science is connected to ideas of purity in the first place. And further more: If indeed natural science plays with ideas of purity, then how do these relate to what natural science does at its heart: put the world into an order. In other words: Is it possible to understand the way modernity relates purity and cleanliness (as what results of order) by looking at natural science and its history?
