Video of DU firings at Eskmeals

In response to a FOI request the Ministry of Defense has released a video of the DU firings carried out at Eskmeals on the Cumbria coast.

The video shows how during the early years of the firing programme significant quantities of  DU were released to atmosphere and how in the later years of the firing programme efforts were made to reduce the discharge of DU to atmosphere

Radium contamination confirmed at Pulham

In January I said in this blog that RAF/RNAS Pulham  provides a typical  example of a site potentially  contaminated with Radium.

It is now clear from a press report that Radium contamination from past defence activities is present on the site.

It was inquiries made  by Milcon Research and Consulting made to the Local Council that in part prompted the Council to look into the issue of Radium contamination at RAF/RNAS Pulham.


It was also clear the response MOD made to an FOI request that the MOD held no information that would help identify if Radium was present on the site.

It is also clear that there are many more sites such as Pulham where radioactive contaminates and other contaminates are present and may pose a risk to human health and the environment. But that the MOD has long since lost records that would identify such sites.

Dalgety Bay the Music Video

An interesting example of how issues involving radioaactivity enter popular culture and have the potential to go viral.

It should noted that its radium not plutonium at Dalgety Bay. But I sure that this detail will be lost for most people watching the video. What will remain is a lasting albeit wrong association of Dalgety Bay with Plutonium.

Potentially contaminated RAF Sites in Scotland.

The Secret Scotland web site provides a good indication of number of sites that the  MOD own or once owned in Scotland. 

Whilst there has been considerable publicity about radioactive contamination other contaminates that may be present include  chemical weapons, heavy metals, asbestos, organic solvents and  ordnance.  It is also notable that Gruinard island in Scotland was the site of a biological warfare test by British military scientists from Porton Down in 1942, during the Second World War. Starting in 1986 a determined effort was made to decontaminate the island.

I believe it 's the MODs social and legal responsibility to identify contamination including radioactivity and the consequent risks to man and the environment at these sites and proactively make this information available online.  In fact there is a stautory duty in the Environmental Infomation Regulations that requires authorities to :-

"(a)  progressively make the information available to the public by electronic means which are easily accessible; and

(b) take reasonable steps to organize the information relevant to its functions with a view to the active and systematic dissemination to the public of the information."


The list below taken from the "Secret Scotland" website lists some of the RAF stations in Scotland.  The list provides a good indication of the scale of the defence estate past and present.

Dalgety Bay on-shore Radium Contamination


Recent press reports about Dalgety bay featuring interviews with Gordon Brown speaking about the ”new” discovery of particles of radioactive onshore at Crowhill wood should not ellicit any surprise, it appears that Gordon Brown is playing  catch-up. 


Links to recent press reports




It’s clear from a report that MOD commissioned Enviros to produce in 2009 that the possibility of onshore contamination was an issue. The report  describes on-shore contamination including investigations of domestic properties and gardens built over the former RNAS/RAF Donibristle salvage area in the 1960s.  This and associated reports were released by Defence Estates in response to a FOI request made 2010.

“Investigation Works Undertaken


8.  As a result of the data from the first Phase Two LQA and in particular the findings relating to Property D in Zone 2A, a further phase of investigations were undertaken. The site works involved both radiological walkover surveys and intrusive investigation, the areas investigated are summarised below (Zone designation used in original Phase Two LQA are shown in brackets):



  • Dalgety Bay Sailing Club Boat Park (Zone 1): Radiological walkover survey of northern area where access was previously not possible;
  • Property A in Zone 2A and Properties H & I in Zone 4B: Radiological walkover survey and random soil sampling from two properties in Zone 4B.
  • Radiological walkover survey and random soil sampling from one property in Zone 2A which had not allowed access during the original Phase Two LQA.
  • Former Salvage Section (Zone 2A): 1m by 1m gridded radiological walkover surveys and soil sampling in the garden areas of six properties. Where radium-226 and elevated count rates were identified removal of disseminated contamination and point sources was undertaken where possible.
  • Internal Monitoring: Count and dose rate surveys covering accessible areas of the ground floor of six properties on the former Salvage Section and the sailing club house. A similar property outside the impacted area was also surveyed to provide a typical background for the developments which could be used as a comparison.”
