HC Deb 13 February 1985 vol 73 c205W
13. Mr. Gerald Bowden

asked the Secretary of State for Scotland what effect a one megaton nuclear overhead burst at a height of 300 miles would have on the equipment and resources in his care.

Mr. Ancram

The Government's policy of deterrence is designed to prevent the use of nuclear weapons. If, however, such an explosion were to occur at 300 miles it would generate a nuclear electromagnetic pulse which could damage unprotected telecommunications and electrical and electronic equipment.

Mr. Moynihan

asked the Secretary of State for Scotland what action he is taking to harden vulnerable equipment in his charge against the effects of nuclear electromagnetic pulse.

Mr. Ancram

We are awaiting the results of current research on this matter before deciding how best to protect vulnerable equipment.
