Dear Mr Dawson, 
 
Thank you for your email of 11 August 2013 requesting the following information: 
 
“I note in a recent answer to an FOI MOD have stated that a maximum of 0.95 GBq of Carbon-14 
was buried by the MOD at Chatham.

Could you please provide me with details of the calculations and assumptions used to arrive at this 
figure and also information about the statistical uncertainty of the figure. 
 
Could you provide me with information about the updated risk assessment for the burial site to take 
account of Carbon 14. 
 
Could you provide information why Carbon 14 has not been included in the environmental survey 
reports. 
 
Also whether or not the MOD has now informed the Environment Agency that Carbon 14 was also 
disposed by burial at Chatham when the original agreement from the then HMIP  was for Cobalt 
60. 
 
Could you tell me if the MOD has provided any information about the radioactive waste burial site 
to the developers of the adjacent land.  If so what information has been provided.” 
 
Your request is being dealt with under the terms of the Environmental Information Regulations 
2004 and will be answered within twenty working days. We will, therefore, write to you again by 9 
September 2013 with either a substantive response or an update on your request. 
 
If you have any queries about this request, please do not hesitate to contact us. Please remember 
to quote reference number 12-08-2013-101543-002 in any future correspondence. 
 
Regards,
