Current interests

Dr Mark Bailey is working on applications of radiation dosimetry including development and commissioning of the suite of new absorbed-dose graphite calorimeters and calculations using Monte Carlo radiation transport codes of perturbation factors for the calorimeters and secondary-standard ion chambers. He is also working in the industrial radiation processing area, offering advice and consultation in dosimetry and modelling for applications including the sterilisation of single-use medical devices by high-energy electron or photon irradiation. He is working on developing other applications of Monte Carlo calculations within the Group.

Mark participates in the activities of the Panel on Gamma and Electron Irradiation, and in the development of standards and guidance documents through ASTM Subcommittee E10.01 on Radiation Processing: Dosimetry and Applications.

Biography

Mark received his undergraduate BSc (Hons) degree in Physics from the University of Birmingham (UK) in July 1986, and his PhD (on 'The interrogation of cement-encapsulated intermediate level waste drums for assaying their fissile and fertile material content') from the same university in December, 1990, while working in the Nuclear Physics Division of the Atomic Energy Research Establishment (AERE) at Harwell, UK. During that time he was also involved with work on 'cold fusion', following the claims of Fleischmann and Pons.

In the later 1990s his work took him into the electron beam irradiation of materials including the terminal sterilisation of medical devices, and ultimately he was Quality Manager for AEA Technology EBIS Ltd, later EBIS Iotron, at Harwell, in charge of process control and dosimetry issues including calibration of the dosimetry systems for the electron beam facilities there. He came to the Radiation Dosimetry Group at NPL in 2004.
