Description

The DTU Department of Health Technology on DTU Risø Campus in Roskilde possesses an MDS Nordion Gamma cell 220 Irradiator S/N 220R. It serves as the national standard for high-dose dosimetry. The Gamma cell was initially installed in 2007 and it was resourced in 2014. The existing loading of the Gamma cell consists of 20 type C-198 sources of total activity 15 kCi (555 TBq) in April 2014. The number of free source positions in the source cage is 28. DTU wants to re-source the Gamma cell to achieve a total activity of 15 kCi (555 TBq) of Co-60. This may be achieved by the addition, or replacement, of sources in existing Gamma cell, or by the supply of an exchange Gamma cell with new sources.

This may be achieved by the addition, or replacement, of sources in existing Gamma cell, or by the supply of an exchange Gamma cell with new sources. The task includes uninstalling of the Gamma cell before the re-source or replacement of sources in the Gamma Cell and reinstalling the Gamma Cell after the re-source or replacement of sources in the Gamma cell. The tenderer can choose to re-source or replace sources rods in the MDS Nordion Gamma cell 220 Ir-radiator S/N 220R outside or on DTU, Risø Campus. Regardless of the place the task is performed, the tenderer has full responsibility for the execution of the task and the tenderer must take all safety measures in connection with the execution of the task, including the incurred costs.
