*Body scan machines to be used on Tube passengers*
By Ben Webster, Transport Correspondent
TUBE passengers are to have their bodies scanned by machines that see
through clothing in an attempt to prevent further terrorist attacks. The
millimetre wave imagers will be used to carry out random checks as
people enter stations after services resume today.
Police and transport officials are also considering installing the
equipment permanently at stations across the network. The technology is
already used to catch illegal immigrants who hide in lorries at Channel
ports but has not previously been used on the Underground because of the
high cost and concerns about privacy.
The scanners can spot the waistcoat bombs usually worn by suicide
bombers and automatically send an alert to nearby officers. Unlike other
scanners, they can cover crowded entrances without the need for people
to be stopped for individual checks.
The system works by measuring the solar radiation reflected by people's
bodies and measuring anything which interferes with the reflection.
