*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.
