The shielded transport and storage containers Posisafe® Type A allows for the safe containment of radioactive sources. It protects operators and the environment from contamination and exposure to alpha, beta, gamma and neutron radiation. Full biological protection of the operator and the environment from contamination and exposition to ionising radiations Two overpack models are proposed to improve radiation protection. Indeed, these overpacks increase the distance factor to the source during package handling operations. A fireproof holding and stability foam guarantees the integrity of the transported radioactive source. This foam absorbs potential shocks of the container with a temperature resistance from -40°C to +70°C. A large locking handle screwed on each model and the lid with an O-ring, ensures the Posisafe® safety and ergonomics. The tight containment of the transported source as well as a good grip and stability of the container are guarenteed. Each model is compatible with our Easypet type fractionating cabinets and our Posijet® preparation and injection unit, capable of receiving multi-dose vials of radiopharmaceuticals.
