The Timepix family of pixel detectors provide quantum-imaging sensitivity, spectral-tracking response in wide field-of-view. These properties are used to develop novel techniques of radiation imaging, particle tracking and high-resolution radiation dosimetry. Complex radiation fields can be characterized in terms of particle-types (electrons, protons, ions, X rays, gamma rays and neutrons), stopping power and direction. Physics principles and description of the developed methods will be given. Together with miniaturized readout electronics and room temperature operation, compact instrumentation and flexible experiments find application in particle radiotherapy, nuclear physics research, environment, cosmic rays and outer space onboard satellites and the ISS. An overview of deployments in outer space and current developments will be included.
