Becky Alexis-Martin Senior Research Fellow in Human Geography within Geography and Environmental Science at the University of Southampton.

We live in a nuclear age, and it has arguably never been more important to explore the human aspects of ionising radiation. Nuclear geography is my chosen field, as it offers a uniquely spatiotemporal and human perspective upon some of the critical issues of our time, including defence, energy production, emergency, security, home, family and activism.

Becky Alexis-Martin is a Research Fellow at the University of Southampton. Since joining as a doctoral researcher in 2012, she has become an established member of the Population, Health and Wellbeing research group, within the faculty of Environmental and Life Sciences.

Her doctoral research has examined differentials in radiation exposure to different demographics during hypothetical nuclear accident scenarios. This work included a combination of statistical and computational modelling approaches, and resulted in the development of a new modelling framework called RADPOP, which improves upon current understanding of how the location of populations in space and time may affect their exposure outcomes. Her other previous academic work has explored the psychosocial impacts of radiation emergencies upon female survivors, the perceptions of risk associated with ionising radiation exposure, and benefits of digital communities for radiation emergency survivor support.

Prior to joining academia, Becky trained in the nuclear industry before working in emergency planning, where she gained practical experience of radiation emergency preparedness. In addition to her academic work, Becky is an enthusiastic science communicator and has previously spoken at the Royal Geographical Society, International Geosciences Union, University of Leeds, PHE, GISRUK, Popfest and Bestival. She has also produced high-quality international science journalism for publishers including The Guardian, UCAS, Resilience Magazine, Guru Magazine and the BNTVA.

RADPOP: A New Modelling Framework for Radiation Protection

Supervisors: Professor David Martin and Dr Sam Cockings

Minimising exposure to ionising radiation during radiation emergencies is an important international public health priority. Radiation emergencies are high impact events, and accidents including Fukushima and Chernobyl have previously had international consequences, due to the atmospheric dispersal of radioactivity. Whilst sophisticated meteorological radiation dispersal models exist, there is a significant deficit pertaining to the availability and implementation of equivalent high-resolution spatiotemporal population statistics. There is an absence of radiation protection-specific population data that can be used characterise and isolate population groups by relevant demographic and spatiotemporal vulnerabilities. There is also no existing modelling framework which uses spatiotemporal population data to predict the behaviour and exposure of a population during a radiation emergency. This work improves upon and applies existing spatiotemporal population and radiation hazard modelling techniques for the purpose of radiation protection, and provides a new agent-based modelling framework for the prediction of spatiotemporal population distribution for a specific hypothetical radiation emergency scenario.
