New radiopharmacy laboratory facilities in La Almunia
IDOM has undertaken the design engineering and construction management of the new facilities for the manufacture of radiopharmaceuticals in La Almunia (Aragón), intended to be used for injections in positron emission tomography. The complex has a radiological alarm system formed by ambient sensors and sensors in the ventilation ducts and a ventilation system in accordance with the requirements of the Spanish Medicines Agency and the corresponding standard of clean rooms (UNE-EN_ISO 14644). This building was validated by the Nuclear Safety Council (CSN) and by the Spanish Medicines Agency prior to its commissioning and start of product marketing.
The laboratory can basically be divided into four zones: administrative, production, radiation area and machine room. The administrative area has an area of approximately 120 m² and a metallic structure with a gabled sandwich roof. The production area corresponds to the area where the products are handled to obtain the final radiopharmaceutical product. It consists of three “hot” laboratories equipped with synthesis cells supplied by COMECER. It also has a quarantine warehouse, raw material warehouse, quality laboratory, pharmacist’s office, shipping area and changing rooms. It is a metal structure with a collaborative floor covering on which the machine room is located.
On the other hand, the radiation zone corresponds to the area where the cyclotron and its control room are located, in addition to the decay zone where both solid and liquid wastes are located until they are completely inertized. This area is executed in reinforced concrete that, particularly in the area of the bunker, has upper cover walls 2 meters thick.
Finally, the machine room, which is located on the roof, includes the UTAS, filters, fans, part of the radio protection probes, the boiler and the chillers.
