HC Deb 07 February 2001 vol 362 cc519-22W
Mr. Swinney

To ask the Secretary of State for Defence how United Kingdom forces in the Balkans were warned to stay clear of areas in which depleted uranium ammunition had been expended; what precautions they were required to take if they were obliged to enter these areas; what monitoring of their physical welfare took place thereafter; and on what date such precautionary warnings and measures were first announced. [145136]

Mr. Spellar:

[holding answer 15 January 2001]: Specialist explosive ordnance disposal (EOD) troops should be aware of the risks presented by expended DU ammunition through routine training and instructions. EOD troops are most at risk from expended DU ammunition when clearing Armoured Fighting Vehicles. In these circumstances, they are required to wear inner cotton gloves, outer heavy PVC gloves, a Service respirator, a full NBC suit and a Thermoluminescent Dosimeter until the presence of DU can be positively discounted

British forces first deployed to Bosnia in 1992. Non-specialist troops were not briefed about the risks of expended DU ammunition because there was no confirmation DU had been used there. In December 2000, NATO confirmed that small quantities of DU ammunition had been used during 1994 and 1995, mainly around Sarajevo. Although the risk to British forces of being exposed to expended DU ammunition in Bosnia is small, on 12 January 2001, arrangements were made for them to be briefed on the risks of DU. SFOR issued guidance for their forces on 14 January 2001.

British forces first deployed to Macedonia on 7 December 1998 and to Kosovo on 12 June 1999. The Kosovo bombing campaign began on 24 March 1999. On 21 April 1999, HQ Land Command issued a Medical Administrative and Technical Instruction down the medical chains of command entitled "Kosovo—Depleted Uranium Hazard". On 9 June 1999, further advice on the DU risk was passed down the operational chain of command by the Permanent Joint Headquarters to HQ BRITFOR in Macedonia. This was disseminated to Brigade level by HQ BRITFOR on 10 June 1999. From June 1999, the Pre-deployment Training Directive for troops deploying to Kosovo specified DU as one of the topics on which troops should be briefed during their pre-deployment course. From July 1999, the Mounting Order issued to units deploying to Kosovo included the following briefing on DU:

  1. "a. Inside Kosovo/Bosnia you may encounter vehicles that have been destroyed or damaged by projectiles made from Depleted Uranium (DU). DU is only very slightly radioactive and is a chemical poison similar to lead.
  2. b. It will not be possible to tell visually if a vehicle has been struck by DU. If this is the case, a heavy toxic powder may be spread inside and outside the vehicle and its immediate surroundings, which may or may not be visible to the naked eye. DU is only hazardous if it is inhaled, eaten or enters the body through a cut or laceration. The radiation will not penetrate clothing of any kind.
  3. c. You are not to climb onto or into vehicles possibly damaged by fighter ground attack aircraft or tanks unless your duties require it. If you do, you should take the following precautions:
    1. (1)If practicable, wear NBC rubber or leather gloves and a cloth oro-nasal facelet (facemask). Full NBC IPE is not necessary.
    2. (2) Spend as little time as practicable on the task.
    3. (3) As soon as possible after completing the task, change your outer clothing and launder it before it is worn again (keeping facelet on while removing dust contaminated clothing). Wash your hands. Do not eat, drink or smoke until you have done this.
  4. d. If you believe that you may have been contaminated with DU, consult your Medical Officer. He/she will have been instructed to annotate your medical records and seek advice from the nearest Environmental Health Team in conjunction with Commander Medical. Urine analysis will confirm whether any contamination has occurred.
  5. e. It is stressed that this hazard is not comparable to that encountered on an NBC battlefield and is trivial compared with combat risks. Even if a DU fragment were to be inhaled or embedded in your body, by whatever means, the risk of you developing cancer over the next 50 years would only be very slightly increased."

Although instructions are in place for all troops in theatre to be briefed on the risks of DU, contrary to the impression I gave in the answer to my hon. Friend the Member for Linlithgow (Mr. Dalyell) on 30 November 2000, Official Report, column 727W, my Department is now aware that not all of them have actually been briefed. It has not been possible to establish how many troops have not been briefed. Furthermore, in August 2000, the pre-deployment course briefing on medical issues, including DU, was dropped because of pressure on the course programme and a perception that it duplicated training at units. Instructions to reinstate it were issued on 12 January 2001.

Mr. Llew Smith

To ask the Secretary of State for Defence on what date, and through which channels, his Department first learned from the United States Administration that depleted uranium shells used by the United States forces in the Balkans conflict were contaminated with plutonium; and if British depleted uranium munitions contain plutonium. [147744]

Mr. Spellar

It has long been known in the scientific community, the nuclear industry and by the Defence Radiological Protection Service that depleted uranium (DU) might contain minute traces of isotopes other than U-238, U-235 and U-234. More recently, details about transuranic contamination of US DU, including by plutonium, were made public by the US Department of Energy in September 1999.

Subsequent work in the US, reported by the Office of the Special Assistant for Gulf War Illness (OSAGWI) in December 2000, showed that the trace quantities of transuranic elements and fission products in US DU armour plate added only 0.8 per cent. to the radiation dose from the DU itself. This is insignificant given the low radioactivity of DU.

Information obtained from the Starmet Corporation, who supply Royal Ordnance with the DU they use to make ammunition, tells us that for each gram of DU, there is 0.000 000 000 005 2 grams of plutonium 238 and 0.000 000 001 2 grams of plutonium 239/240. The activity contribution of the three naturally occurring uranium isotopes in 1 gram of DU is 14,818 becquerels. The plutonium contributes an extra 6.14 becquerels, or 0.04 per cent. of the radiation of the naturally occurring uranium isotopes.

Mr.Llwyd

To ask the Secretary of State for Defence how much(a) plutonium and (b) other highly radioactive particles was contained in the depleted uranium shells fired by Britain during the Gulf War. [147379]

Mr.Spellar

Information obtained from Starmet Corporation, the firm who supply Royal Ordnance with the DU they use to make ammunition, tells us that each gram of DU contains:

Grammes
Uranium-238 0.997 9
Uranium-235 0.001 99
Uranium-234 0.000 01
Uranium-236 0.000 003
Technecium-99 0.000 000 71
Neptunium-237 0.000 000 22
Plutonium-239/240 0.000 000 001 2
Americium-243 0.000 000 001
Americium-241 0.000 000 000 017
Plutonium-238 0.000 000 000 005 2

Any significant increase in the quantity of highly radioactive particles would be detected by our routine radiation monitoring.

DU used in the manufacture of the CHARM 1 round, used at the time of the Gulf conflict, came from the same source.

Mr. Llew Smith

To ask the Secretary of State for Defence if he will set out the source of the depleted uranium used to manufacture depleted uranium-tipped projectiles in the British military stockpile; and what steps are taken to remove high activity contaminants from the depleted uranium stocks before manufacture into weapons. [145283]

Mr. Spellar

I will write to my hon. Friend and a copy of my letter will be placed in the Library of the House.

Mrs. Mahon

To ask the Secretary of State for Defence what assessment he has made of the findings of the UN environmental programme that munition tips at sites attacked by NATO during the Kosovo conflict contain traces of highly radioactive enriched uranium, U-236; and if he will make a statement. [147413]

Mr. Spellar

According to preliminary work carried out by the United Nations Environmental Project (UNEP), U-236 makes up 0.0028 per cent. of the uranium found in DU penetrators in Kosovo. They also judge that this amount is too small to change the radiotoxicity compared to DU without U-236. These are just preliminary findings, though, and we await their final assessment.

The U-236 in this DU is from the trace amounts that are in enrichment facilities and from the small amounts of DU that are from the reprocessing of the uranium extracted from nuclear fuel. Work in the US, and reported by the Office of the Special Assistant for Gulf War Illness (OSAGWI) in December 2000, showed that the trace quantities of transuranic elements and fission products in US DU armour plate, including U-236, added only 0.8 per cent. to the radiation dose from the DU itself.

Mr. Horam

To ask the Secretary of State for Defence if depleted uranium is stored at Fort Halstead. [148271]

Mr. Spellar

Depleted uranium (DU) is stored at Fort Halstead. It is being held in accordance with statutory regulations and to the satisfaction of both the Environment Agency and the Ministry of Defence's statutory radiation protection advisers. DU rounds have not been fired there.

Mr. Drew

To ask the Secretary of State for Defence, pursuant to his answer to the hon. Member for Stroud of 15 January 2001,Official Report, column 44W, on depleted uranium, when he plans to write to the hon. Member. [148843]

Mr. Spellar

I shall write to my hon. Friend in due course about the information he has requested and a copy of my letter will be placed in the Library of the House.

Mr. Maclennan

To ask the Secretary of State for Defence if depleted uranium-based ammunition has been authorised in the past for use at(a) Tam Air Weapons Range and (b) Cape Wrath, by (i) UK forces and (ii) overseas forces. [149212]

Mr. Spellar

Depleted Uranium (DU)-based ammunition has never been authorised for use by UK or overseas forces at Tain Air Weapons Range, or at Cape Wrath Range.
