Richard Parker
Richard has nearly 20 year’s experience of working in the nuclear industry.
For the last six years he has worked as an RPA, achieving accreditation as a Radiation Protection Adviser under the RPA2000 scheme in April 2004.
Richard currently has a large portfolio of clients for whom he provides RPA advice, these include: several companies that use radioactive sources in their processes; clients that have a historical legacy of radioactive objects and projects funded by the Department of Trade and Industry in the former Soviet Union. This involves regular travel to north-west Russia to assist in the management of the FSU nuclear legacy.
Richard started work for UKAEA in 1986 in the Radiation Dosimetry Department of Health Physics at Harwell. His role was to assist with the development of methods for the accurate measurement of the airborne discharges from nuclear plant and assessment of aerosols in the workplace. With AEA Technology, he went on to manage a team of specialists who carried out assessments of the suitability and efficiency of the installed aerial discharge sampling and monitoring systems throughout the UK nuclear industry.
Since January 1999, Richard has worked for the RPA Service and has managed the Health Physics support contract for three Sizewell B refuelling outages, carrying out the day to day management of teams of up to sixty HP personnel. He has also managed and carried out surveys using the GPS based Groundhog system at various sites throughout the UK and at nuclear power stations in Canada.
Richard is an experienced trainer and known for his considerable patience and ability to explain concepts of radiation protection.
