SARAD GmbH was founded by the physician Prof. Dr. Thomas Streil in 1993. The company started as a service provider assessing radioactive polluted properties with regard to their later decontamination. After a short time, the development of electronic measuring instruments was started. In 1994, SARAD presented the first radon monitor by its own production. Since 1997, the development and manufacturing of premium measuring equipment are the pillars the company is built on. Due to its positive business performance, the company was able to move into its own corporate building in 2000. Step by step, the range of products was extended in the following years.
