Dalgety Bay

Background

Dalgety Bay is located on the north side of the Forth Estuary in Fife.

Radioactive material was first detected on a part of the foreshore at Dalgety Bay in 1990. Monitoring has been undertaken by both SEPA and the Ministry of Defence and periodically radioactive material has been removed. It is thought that the contamination originates from the residue of radium coated instrument panels from military aircraft incinerated and land-filled in the area at end of World War II.

The radium used by the MoD was primarily in luminescent paints. Radium based luminescent paint was typically made by mixing a radium salt, zinc sulphide and a carrier material (typically varnish or lacquer).

Recent history

Many surveys have been undertaken on the beach to determine the potential numbers of items present and possible implications for public health. SEPA has undertaken a number of recent monitoring and assessment exercises at Dalgety Bay and these can be viewed on the Dalgety Bay reports page on our website, this includes the 2011 September Dalgety Bay Assessment. pdf link (2.75mb)

Below are data for the sources SEPA recovered from Dalgety Bay between September 2011 and October 2012:

The monitoring of shellfish from Dalgety Bay started in February 2012. Cockles, winkles and mussels are being collected on a monthly basis (subject to sample availability) from a number of locations within the bay. Below are the results of the monitoring conducted in February – July 2012. The monitoring is still ongoing and the results will be updated on a quarterly basis.

Current situation

The total number of radioactive sources (particles) that have now been recovered since the beginning of our investigation in September 2011 is over 1,000. Of these sources, five had a radioactivity content of greater than 1 MBq of Radium-226 (1 Mega Becquerel = 1,000,000 Bq). Four of these sources were located in the area which is currently cordoned off and the fifth on an area in front of the headland which is only accessible at low tide.

Currently, the MoD is undertaking a programme of investigation to determine the extent and magnitude of the contamination at Dalgety Bay. This investigation forms part of our inspection of the land under the Radioactive Contaminated Land (Scotland) Regulations 2007 and will lead to the development of remediation options. From those options, we will determine the most appropriate remediation plan. In the meantime, the MoD has committed to a programme of monthly monitoring and retrieval in the affected area at Dalgety Bay. We have oversight of this programme. The detection and removal of radioactive particles close to the surface of the land reduces the possibility of a member of the public coming into contact with these particles. However, we urge the public to continue to follow the advice on signs at the site – don’t remove anything from the beach and wash your hands upon leaving the area.
