Textualising British Politics: Deconstructing the subject of British foreign policy

British politics has been described as a sub-discipline crying out for methodological and ideational cross-fertilisation. Where other areas of political science have benefited from new ideas, British politics has remained largely atheoretical and underdeveloped. This has changed recently with the rise of interpretivism but the study of British politics would also benefit from more serious engagement with poststructuralism. With this in mind, I examine how the thought of Jacques Derrida and deconstruction could be useful for thinking through the foundations of British politics, re-examining what appears natural or given and revealing the problematic and contradictory status of these foundations. After suggesting the need to 'textualise' British politics', I illustrate how deconstruction operates in a specific context, that of British foreign policy since 1997. This exploration reveals how certain decisions (such as the invasion of Iraq in 2003) became possible in the first place, and how their basis in an idea of an 'us' and a 'them', a coherent, autonomous subject separate from its object, is deeply problematic. Such a critical reading of British politics is impossible within the dominant interpretivist framework, and opens up new possibilities for thought which form an important supplement to existing ways of studying the field.

Personnel radiation dose considerations in the use of an integrated PET–CT scanner for radiotherapy treatment planning of an integrated PET-CT scanner for radiotherapy treatment planning

The acquisition of radiotherapy planning scans on positron emission tomography (PET)-CT scanners requires the involvement of radiotherapy radiographers. This study assessed the radiation dose received by these radiographers during this process. Radiotherapy planning F- fluorodeoxyglucose (F-FDG) PET-CT scans were acquired for 28 non-small cell lung cancer patients. In order to minimise the radiation dose received, a two-stage process was used in which the most time-consuming part of the set-up was performed before the patient received their F-FDG injection. Throughout this process, the radiographers wore electronic personal dosemeters and recorded the doses received at different stages of the process. The mean total radiation dose received by a radiotherapy radiographer was 5.1±2.6 mSv per patient. The use of the two-stage process reduced the time spent in close proximity to the patient by approximately a factor of four. The two-stage process was effective in keeping radiation dose to a minimum. The use of a pre-injection set-up session reduces the radiation dose to the radiotherapy radiographers because of their involvement in PET-CT radiotherapy treatment planning scans by approximately a factor of three.
