Update on public health issues related to Polonium-210 investigation

11 December 2006

The Health Protection Agency is continuing to provide expert advice on the public health issues surrounding the death of Mr. Alexander Litvinenko. Throughout, our primary concern has been to protect the public.

Po-210 can only represent a radiation hazard if it is taken into the body - by breathing it in, by taking it into the mouth, or if it gets into a wound. It is not a radiological hazard as long as it remains outside the body. Most traces of it can be eliminated through hand-washing, or washing machine and dishwasher cycles for clothes, plates etc.

On the basis of the monitoring results received so far from a range of sites we still believe that the risk to the general public of having been exposed to Po-210 is likely to be very low.

Test results update

The Agency's public health follow-up has included testing urine samples from those in close contact with Mr. Litvinenko, those who worked or were present in the affected areas and, where appropriate, those who called for advice via NHS Direct.

• Some 76 health care workers were identified as having been in close contact with Mr. Litvinenko and as a precaution they were invited to provide urine samples for testing. Of the 76, 69 accepted the offer of urine tests. All results were negative.
• The Health Protection Agency has today been asked by the police to provide additional occupational health testing for police officers.  The Agency will provide appropriate support in terms of providing laboratory testing, dose exposure assessments and, if necessary, clinical assistance.
• 233 urine samples so far tested by the Agency have found nothing of concern. The Agency will be contacting these people to inform them of their results.
• There are 8 samples which have shown exposure to some Polonium-210 ( Po-210). The levels are not significant enough to result in any illness in the short term and any increased risk in the long term is likely to be very small.
• Calls to NHS Direct have declined significantly over the last 24 hours, with the most recently published figure of 3,625 representing the latest consolidated total
• By noon Monday December 11, the HPA had followed up 620 people who, following assessment, needed further investigation. 204 of these people had been in the Pine Bar on 1 Nov and had already been in touch with NHS Direct. These people are now being re-contacted.
• The total number of people - as of midnight Sun Dec 10 - referred as a precaution to a specialist outpatient assessment clinic for possible radiological exposure assessment is 29 (27 from NHS Direct, and 2 via other routes)

 

The police investigation continues. We will provide further public information as appropriate.

Notes to Editors:

1. Preliminary results received from seven members of staff working in The Pine Bar of the Millennium Hotel on Nov 1 show that they appear to have had some exposure to Polonium-210.
   Following this information we felt it prudent to assess any other staff working in The Pine Bar of the Millennium Hotel, on Oct 31 and Nov 2. We are working with the hotel management to try and identify any other relevant staff. We have also advised that any member of the public in The Pine Bar on Oct 31 and Nov 2 (in addition to Nov 1) contact NHS Direct on 0845 4647 who will pass on their details to the HPA for further assessment.
   Our advice has also been that anyone who was in The Pine Bar on Nov 1, who has not yet contacted NHS Direct, is invited to do so.
2. The Agency is writing to offer further advice to those people who were in The Pine Bar on Nov 1 and who have already contacted NHS Direct. A special helpline, staffed by experienced HPA staff, has been set up. If any of these people want this, a urine sample will be tested. Arrangements will be made for information to be provided to international guests.
3. Overseas visitors who were in the Pine Bar of the Millennium Hotel on Oct 31, Nov 1 and Nov 2 should email the Health Protection Agency for advice: overseasadvice@hpa.org.uk. If you do not have access to email you can contact NHS Direct on 00 (44) 845 4647 but only via a mobile telephone if you are calling from abroad.
