The Risø TL/OSL-DA-20 reader enables automated measurements of thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) signals. As the measurement system is highly sensitive and includes a reference radiation source, it is widely used for determining radiation doses in natural and artificial materials with applications in geological and archaeological dating. The laboratory is further equipped with all necessary facilities for sample preparation, e.g., extractor hoods and dark rooms.
