Radiolabeling optimization and reduced staff radiation exposure for high-dose 90Y-ibritumomab tiuxetan (HD-Zevalin).

Introduction: (90)Y-Zevalin labeling may cause severe finger radiation exposure, especially in high-dose protocols (HD-Zevalin), where up to 7.4 GBq could be injected. In this work, we optimized the labeling of HD-Zevalin with special regard to simplicity, speed, safety and radiation protection.

Distribution of heavy metals in sediments of the Venice Lagoon: the role of the industrial area.

We sampled eighteen stations in the lagoon and nine in the canals of the industrial area of Porto Marghera. At each lagoon site a short core, 10 cm long, was taken and immediately extruded to obtain four slices 2.5 cm thick.
