HC Deb 28 June 1991 vol 193 cc592-3W
Mr. Boyes

To ask the Secretary of State for Defence if he will make a statement on his Department's conclusions regarding the capability of Soviet neutron and gamma ray detector equipment to verify the presence of nuclear weapons aboard naval vessles.

Mr. Archie Hamilton

In 1989 a Soviet agency conducted experiments with the National Resources Defence Council—a United States non-governmental body—in which it was demonstrated that under favourable circumstances the Soviet Union has the capability to detect some types of nuclear weapons at short range using neutron and gamma ray detection equipment.
