ABSTRACT
An x-ray microprobe, which utilises a small laboratory x-ray source with a carbon target and a zone plate to form a fine focus, has been used for initial studies of cellular radiation response. It is not yet clear whether carbon K x-rays exhibit the hypersensitivity at very low doses for 240 kVp x-rays, which manifests itself predominately with sparsely ionising radiation. There is some evidence to support the phenomenon of radiation induced bystander effects whereby unexposed neighbours of irradiated cells also exhibit a response.

    At the ESRF micro-fluorescence, imaging and diffraction (μ-FID) beamline ID 22, a microimaging and tomography setup has been operational for several months. The coherence properties of the high-energy X-ray undulator beam at ID 22 make the setup especially suited for phase-contrast tomography...
