    Linear Accelerator - Product Code IYE
  • Reason
    Radiation leak: when used with field sizes of 5cm x 5cm or smaller, product may leak radiation at a distance of 2 cm from the side of the applicator body up to 13%, in excess of iec standards.
  • Action
    Siemens sent a Customer Safety Advisory Notice dated 12/12/2007 to DEVA customers. The letter stated that Siemens would temporarily disable energies 5MeV and below for all customers that decide to continue using the DEVA, resulting in the temporary unavailability of energies 5MeV and below for all available. Customers wishing not to have these energies blocked must return their DEVA and they would be contacted by a local Siemens rep to schedule a service appointment. The letter stated that as a preventative measure that those customers should refrain from using the DEVA with any combination of energies 5MeV and below with field sizes smaller than 6cm x 6cm. The firm suggested using the fixed field electron applicators and cutouts with these energies and field sizes. Siemens will release a new control console software in 2008 for free-of-charge, that will limit the use of the DEVA to energies 6MeV and above, while allowing the use of lower energies using the fixed field electron applicatiors.
