In the 1940s the trade mark Ytong was introduced, but often referred to as "blue concrete" in Sweden, due to its blueish tinge. This version of Ytong was produced from alum slate, which due to its combustible carbon content was beneficial to use in the production process. The competing concrete brand Siporex used other raw materials. However, the slate deposits used for Ytong also contains uranium, which makes the material give off small amounts of radioactive radon gas to the surrounding air. In 1972, the Swedish Agency of Radiation Protection pointed out the unsuitability of a radon-emitting construction material, and production ceased in 1975. Ytong produced after 1975 has used other raw materials, without the uranium content.
