T956 - X Ray Irradiation Machine

Tender description

The University of Essex is seeking a supplier to provide a versatile X-ray irradiator to study radiotoxicity, radioresistance, infectious viruses and healthy ageing along with a 30 month service contract. Lot 1: We want to bring to the School of Life Sciences an X-Ray research irradiator cabinet for biological samples, to support studies by several groups in the School of Life Sciences of the Authority, including: - Biology of long-term radiation toxicity - Development and characterisation of new radio-sensitiser drugs - Inactivation of infectious viruses for molecular studies outside Containment Level 2 laboratories. - Others that may be pursued in the future, with internal or external collaborators. To support this variety of studies, the instrument must have the following capabilities: - To produce a broad range of photon energies (from the low tens of keV to at least 300 keV, so the biological effects can be as similar as possible to those of 137Cs-generated gamma rays). - To control the current intensity of origin and the distance to source, to have a broad range of dose rates available. - To include several beam filters, to have different levels of ‘hardness’ of the incident energy spectrum.
