2016 - Pete Burgess: 'RP in 50 Years - Very Fallible Predictions'

Pete Burgess started work in the Health Physics Instruments Group of NRPB in 1975. He moved from there to UKAEA in 2002, mostly because it was a great opportunity to broaden the area of work. He stayed there for 4 years, happily helping people at Dounreay, Harwell and Winfrith demolish the sites efficiently while staying within the legal obligations. He then moved to NPL, which was very different. His main influence at NPL was to encourage the staff to look at the point of application of the standards and to consider how best they could help those at the point of application. After 2 years, he moved to Nuvia, for the first time working for a genuinely commercial organisation. That in itself was a major challenge but it led to an involvement in the heavier engineering aspects of dealing with ionising radiation. It is interesting how different engineers and scientists views can be. Then he was tempted away by a very good offer into private consultancy, which has given tremendous freedom.

This breadth of work, and the range of organisations worked with – SRP, AURPO, IAEA, HSE, EA, NII, ONR, BNFL, AWE, universities and a whole host of commercial companies, particularly the wonderful Mini Instruments Ltd – has been great fun. But even more it’s been the people. 

2015 - Roger Coates: 'A Journey Towards Radiation Protection Culture'

Roger Coates is an Honorary Fellow and former President of the Society. He worked for 30 years in the nuclear industry with BNFL, with responsibilities encompassing radiation protection, nuclear safety, conventional safety and environmental issues, retiring as Director of Environment, Health and Safety. He then spent 18 months with IAEA in Vienna.

Roger has extensive radiological protection experience across the whole field of operations, environment and the underpinning standards and science. He was a Member of the ICRP Task Group on Occupational Exposure and a co-author of the resulting ICRP Publication 75.  He was the Founder Chairman of the World Nuclear Association’s Radiological Protection Working Group.

Roger is spending a very active semi-retirement. He is President of the International Radiation Protection Association and was Congress President for the IRPA13 Glasgow Congress in 2012. He is also a Non-Executive Director of LLW Repository Ltd, as well as being adviser to several UK nuclear organisations He is involved with IAEA as a consultant on the Iraq Decommissioning Project and the Nuclear Law Institute.

2014 - John Croft: 'ALARA, RP Culutre and More: Joining-up the Dots and the People'

John Croft is an Honorary Fellow and a former president of SRP. For his entire career he worked for the National Radiological Protection Board (NRPB); its predecessor, the Radiological Protection Service and its successor, the Health Protection Agency (HPA). He has experience of many aspects of radiation protection, including RPA work, the development of national and international standards, the safety and security of radioactive sources, together with emergency preparedness and response. Of particular relevance to his presentation he was heavily involved over several decades with the development, understanding and practical implementation of ALARA.

He has acted as consultant to a number of international organisations including, the European Commission, the World Health Organisation (WHO), the International Atomic Energy Agency (IAEA) and the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). He has led a number of IAEA missions to investigate major radiation accidents in Brazil, El Salvador, Belarus, Israel and Bolivia.

When, in 2003, NRPB became part of the newly formed HPA, he became the Head of Emergency Response, with the responsibility to develop coherent emergency response arrangements that covered not just radiological incidents, but all public health emergencies; including CBRN attacks, chemical incidents and infectious diseases outbreaks. He was heavily involved in the response to the London Polonium Incident in 2006. He retired from HPA in 2007, but continues to be active in work for SRP.
