Dounreay Particles Advisory Group (DPAG) 4th Report: SEPA Response

EXT01 – B04

The Scottish Environment Protection Agency (SEPA) which is advised by DPAG, has today released the group's Fourth Report. It details the work that has been done on the potential for future sources of particles, particle characteristics and behaviour, evaluation of the performance of detection systems and commentary on the adequacy of existing monitoring.

Considerable progress has been made since the release of the Third Report in November 2006, which brought together the diverse aspects of radioactive particles around Dounreay. There is a greater understanding of the properties of the particles being found, which has allowed the group to reconsider any potential health effects. The TROL system for detecting particles in the sea, and the Groundhog Evolution 2 monitoring system have significantly improved particle discovery.

SEPA's Radioactive Substances Unit Manager, Byron Tilly, said:

"This report makes a further important contribution to our understanding of the situation at Dounreay. It follows on from the good work done previously by DPAG, and will enable us to improve our knowledge of the sources of particles and how they behave. This will inform the future arrangements for retrieval of particles, monitoring of the environment around Dounreay, and decommissioning of the old diffuser through which effluent was historically discharged. "
