FBI official: Suicide bombers remain a daily concernBy PAT MILTON - The Associated Press
NEW YORK - Suicide bombers have not hit the United States since the 9/11terrorist hijacking attacks, but they remain a constant concern because of their prevalence around the globe and determination to die for their causes, according to the FBI's chief of counterterrorism…

Opinion
Airport Security Is A Colossal Joke
By Chris Friend - The Philadelphia (PA) Evening Bulletin
If you're wondering what the sound is that you keep hearing, it's laughtercoming from our enemies. Make no mistake, they're laughing at us, not withus. And it's humiliating. As a matter of fact, al-Qaida and company aretickled to death that they have such an accommodating and bumblingadversary. They could not script it any better if they tried.
At issue is the pathetic handling of airport security in the United States.For those who have been isolated in the Antarctic for the past six years,airplanes are the preferred method of terrorists for carrying outspectacular attacks. It was reasonable, therefore, to think that in theaftermath of 9/11, America's leaders would have devised ways tosignificantly protect the economic lifeblood of the country, air travel. Ofcourse, since competence in government is a key component for leadership,that goal was never achieved…

Airport bomb detection crippled
By Amornrat Mahithirook
Thailand - The Bangkok Post
Ten of the 26 computer tomography X-ray (CTX) machines used to detect bombs
during baggage scanning at Suvarnabhumi airport remain inoperable and need
replacement parts, Deputy Transport Minister Sansern Wongcha-um said
yesterday.

Airport X-ray machines fail police drug smuggling test
By Multa Fidrus
Indonesia - The Jakarta Post
The botched demonstration of an X-ray machine at Soekarno-Hatta
International Airport has exposed the facility as a weak spot in the
government's efforts to combat the drug trade.
The machine failed to detect crystal methamphetamine, locally known as shabu
shabu, which had been deliberately placed in a bag as part of a police
demonstration.
The demonstration was part of a case against a Nepalese man accused of
smuggling 650 grams of crystal methamphetamine through the airport.
"The reenactment at the airport was just to see how the X-ray machines
inspected the contents of passengers' suitcases. (Now) we've all seen how
drugs can pass through the airport," Sr. Comr. Siswandi from the National
Police said.

Is OIA vulnerable?In a test of federal security officers, more than half fail to detect dangerous items on X-ray screens.
By Beth Kassab
The Orlando (FL) Sentinel
More than half the federal security force at Orlando International Airport failed a key test this summer used to
measure how well security officers detect explosives, guns and other threats at the passenger checkpoints.
While the Transportation Security Administration said the test is just one method used to evaluate job
performance, it highlights vulnerability in the system at a time when heightened security alerts are elevating the
pressure on officers.
A recent alleged terrorist plot to blow up airliners heading from England to the United States prompted security
clampdowns at airports on both sides of the Atlantic, but poor test results and low morale among local TSA
officers raise questions about safety at Orlando International, the state's busiest passenger airport.

"Puffer" bomb screeners a bust"We all laugh about it [the trace portals] now because we never know if it's working
or not" - TSA Screening Supervisor at Newark Airport By RON MARSICO
The Newark (NJ) Ledger
Megan Tlusty, an intern with the Transportation Security Administration, goes through a new explosive-detection
machine at Newark Liberty International Airport in this 2005 photo. The machine uses a strong puff of air to dislodge
and detect traces of explosives.
Three years ago, with great fanfare, federal officials unveiled a terror-fighting machine they called the "puff portal," a
contraption that resembled a Star Trek transporter booth and was designed to detect explosives at airport checkpoints
with unprecedented precision.
When a passenger stepped inside the puff portal, so the officials said, the machine would send sharp bursts of air to
dislodge particles from the body, hair and clothing, and analyze them for microscopic traces of explosives.
But the expensive devices — each costs about $160,000 — have been largely ineffectual and the much ballyhooed $30
million program is starting to look like a techno-folly to some critics.

X-ray Backscattering
• Low energy, low dose x-ray backscattering system are experimenting to find materials of other than human composition concealed under clothing.
• x-ray backscatter (vs. absorption) is higher at lower Z
• Exposure ~ 3 microREM (10-5 - 10-6 of medical x-ray) (~ 10-2 of additional exposure due to aircraft flight altitude and time)
• Energy not explicitly disclosed, but penetration “only a few cm” suggests the range.

component to a radio frequency pulse “in

• The answer is unique: each component has a

The resolution is determined by the gradient strength which depends on the power of
the RF amplifier and by the low gyromagnetic ratio of the quadrupole nuclei.
The variation of the B1 amplitude through the object encodes the spin localization in the
nutation frequency.

Line Narrowing in Solids by Double Resonance Irradiation

Cl

H

H
In some quadrupole systems which do not couple
appreciably among themselves, the lifetime of the
transverse coherence is limited by the strong dipolar
interaction with nearby protons.
B. Herzog and E.L. Hahn Phys. Rev. 103,148 (1956 )
B0 = 20 Gauss
B2 = 7 Gauss
= 1 ms
The double resonance method is applied as follows: A small magnetic field (~20G) is
applied and a continuous on-resonance proton irradiation introduces a forced
reorientation that averages the local dipolar field at quadrupole positions. It leads to a
increasing of the T2 value.

Double Resonance Imaging Method (DRI)
To achieve spatial localization a static magnetic field gradient is applied to spread the proton
resonance, while the protons are irradiated at a fixed frequency, defining a slice position where
the resonance condition is reached.
To obtain a 1D projection the object is placed in the magnetic field gradient and the
homogeneous component B0 is decreased in a step by step manner moving the resonance slice
position through the object.

NQR: from Imaging to Explosives Detectors
Conclusions
• We have moved along the path from the Basic Research towards a Production
Prototype:
Basic Research >>>> Applied research >>> Technological Development >>> Laboratory
Prototype >>> Homologated Production Prototype
• Multidisciplinary common work is convenient.
• Young people is easy to integrate in a multidisciplinary group.
• Support from the government is necessary.
