The Environmental and Health Radiochemistry Unit (URAIS) is a laboratory created in 2001 at the Universitat Rovira i Virgili (URV) in collaboration with the Tarragona Water Consortium (CAT). It is dedicated to providing analytical services and research in the field of environmental radioactivity. The laboratory is managed by the Chromatography, Environmental Applications Group of the Department of Analytical Chemistry and Organic Chemistry of the Universitat Rovira i Virgili.
URAIS is located within the Water Quality Laboratory (LQAIGUA) of the Tarragona Water Consortium, which is located in the drinking water treatment plant of L'Ampolla (Tarragona). URAIS has two laboratories and an office and other rooms shared with the rest of the LQAIGUA units (organic, inorganic and microbiology) to carry out all its activities.
