NUCLEAR FORENSIC SCIENCE
  • Francisco Bencosme
  • Instructor Ms Villani

2
Nuclear Forensics
  • Nuclear forensics is the protection of nucleic
    materials and facilities. It also deals with the
    prevention and detection of illegal trafficking
    of nuclear and radioactive materials.

3
Nuclear Forensics and Scientists
  • To identify the nature of the seized material
  • To assess the immediate danger involved and
    advise the law enforcement authorities on the
    procedures to be followed
  • To confirm whether an offence has been committed
    under the appropriate Nuclear Regulations
  • To locate the original source of the material if
    possible
  • To identify the possible route it has taken up to
    the point of seizure
  • To give an opinion on the probable intended use
    of the material.

4
History of Nuclear Forensics
  • Nuclear forensics began at the Laboratory under
    the leadership of scientist Sid Niemeyer in the
    mid-1990s, and Livermore has maintained a leading
    role because of a collective group effort. The
    Laboratory has been involved in nuclear forensics
    and attribution for more than 15 years, since the
    collapse of the Soviet Union sparked concerns
    about the diversion of nuclear materials from
    former Soviet nuclear laboratories and other
    sites. Livermores capabilities in radiochemistry
    and nuclear physics, originally developed for the
    nations underground nuclear testing program,
    were adapted for use in nuclear forensics and
    attribution.

5
What Nuclear Researchers Do
  • Nuclear forensic covers a broad spectrum of
    possible substances. A main point is the
    detection, recovery and investigation into the
    origins of a stolen container of the chemicals.
  • Researchers analyze the chemicals and isotope
    composition. They measure the amount of trace
    elements and the ratio of parent isotope to
    daughter isotope. They also measure the shape,
    size, and texture of the chemical sample.
  • These measurements help determine the source,
    location, and the age of the sample.

6
What Instruments do they use?
  • Researchers use techniques such as electron
    microscopy, x-ray diffraction, and mass
    spectrometry to analyze interdicted radiological
    and nuclear materials.

7
Nuclear Forensics and Signatures
  • Nuclear Forensic focuses also on identifying
    signatures. These are physical, chemical, and
    isotopic characteristics that make nucleic and
    radiological materials different from each other.
  • Livermore scientists and the Office of Laboratory
    Counsel have compiled a library that is used to
    check unknown samples against a database. They
    use statistics to identify unique signatures in
    each chemical sample.

8
How can they stop Terrorism?
  • Nuclear forensics is able to explore the origins
    of a nuclear missile, thereby using it in solving
    nuclear warfare.
  • Scientists can measure ratios of certain isotopes
    to find out how long the chemicals have been in
    the reactor.
  • Scientists can measure ratios of isotopes in
    uranium to find out its original location.
  • Scientists can trace for impurities like
    gadolinium to find out how to bomb was created.

9
Fighting Nuclear Terrorism
  • Awareness after September 11.
  • Every possibly available means might be used by
    terrorists.
  • Prevention.
  • Safeguarding and securing nuclear material.
  • Fighting illicit trafficking.
  • Early detection.
  • Preparedness.
  • Develop model action plan.
  • Assistance in analyzing fall-out.
  • Evaluation of scenarios.

10
Threats Posed by Nuclear Terrorism
  • Crude Nuclear Weapon.
  • (requiring larger amount of nuclear material and
    expertise in
  • construction, means of delivery)
  • Dirty parcel or letter bombs.
  • (conventional explosive bomb laced with nuclear
    or radioactive
  • material, easy to construct, no specific amount
    of nuclear material necessary, no delivery
    problems)
  • Quiet dispersion of nuclear material.
  • (direct physical dispersion, no specific amount
    of nuclear or radioactive material required)

11
What can happen?
  • Extinction!!!
  • Mohammed SidAhmed in 2004 explains
  • What would be the consequences of a nuclear
    attack by terrorists? Even if it fails, it would
    further exacerbate the negative features of the
    new and frightening world in which we are now
    living. Societies would close in on themselves,
    police measures would be stepped up at the
    expense of human rights, tensions between
    civilisations and religions would rise and ethnic
    conflicts would proliferate. It would also speed
    up the arms race and develop the awareness that a
    different type of world order is imperative if
    humankind is to survive. But the still more
    critical scenario is if the attack succeeds. This
    could lead to a third world war, from which no
    one will emerge victorious. Unlike a conventional
    war which ends when one side triumphs over
    another, this war will be without winners and
    losers. When nuclear pollution infects the whole
    planet, we will all be losers.

12
What more can happen?
  • Global Nuclear War!
  • Louis Rene Beres explain the terminal impacts of
    nuclear terrorism
  • Nuclear terrorism could even spark full-scale war
    between states. Such war could involve the entire
    spectrum of nuclear-conflict possibilities,
    ranging from a nuclear attack upon a non-nuclear
    state to systemwide nuclear war. How might such
    far-reaching consequences of nuclear terrorism
    come about? Perhaps the most likely way would
    involve a terrorist nuclear assault against a
    state by terrorists hosted in another state. For
    example, consider the following scenario Early
    in the 1990s, Israel and its Arab-state neighbors
    finally stand ready to conclude a comprehensive,
    multilateral peace settlement. With a bilateral
    treaty between Israel and Egypt already many
    years old, only the interests of the
    Palestiniansas defined by the PLOseem to have
    been left out. On the eve of the proposed signing
    of the peace agreement, half a dozen crude
    nuclear explosives in the one-kiloton range
    detonate in as many Israeli cities. Public grief
    in Israel over the many thousands dead ands
    maimed is matched only by the outcry for revenge.
    In response to the public mood, the government of
    Israel initiates selected strikes against
    terrorist strongholds in Lebanon, whereupon
    Lebanese Shiite forces and Syria retaliate
    against Israel. Before long, the entire region is
    ablaze, conflict has escalated to nuclear forms,
    and all countries in the area have suffered
    unprecedented destruction. Of course, such a
    scenario is fraught with the makings of even
    wider destruction. How would the United States
    react to the situation in the Middle East? What
    would be the Soviet response? It is certainly
    conceivable that a chain reaction of interstate
    nuclear conflict could ensure, one that would
    ultimately involve the superpowers or even every
    nuclear-weapons state on the planet. What,
    exactly, would this mean? Whether the terms of
    assessment be statistical or human, the
    consequences of nuclear war require an entirely
    new paradigm of death. Only such a paradigm would
    allow us a proper framework for absorbing the
    vision of near-total obliteration and the outer
    limits of human destructiveness. Any nuclear war
    would have effectively permanent and irreversible
    consequences. Whatever the actual extent of
    injuries and fatalities, such a war would entomb
    the spirit of the entire species in a planetary
    casket strewn with shorn bodies and imbecile
    imaginations.

13
Can terrorists Acquire Nuclear weapons? Some Say
Yes
  • Alyn Ware in Rule of Force or Rule of Law? Legal
    Responses to Nuclear Threats from Terrorism,
    Proliferation, and War, says
  • "acquisition of a nuclear explosive device, by
    theft or construction, and its threat or use by a
    terrorist organization, is becoming more likely.
    In Russia, there is concern over security of
    their nuclear warheads, particularly those
    decommissioned and on their tactical delivery
    vehicles. There is particular concern regarding
    suitcase-sized "mini-nukes," though even larger
    nuclear weapons could be stolen with a large
    truck. n29 Of even greater concern is the
    possibility that a sub-national group could
    acquire the key ingredients for a nuclear
    warhead, highly enriched uranium or plutonium, to
    manufacture a bomb. The smuggling of highly
    enriched uranium has been intercepted on a couple
    of occasions, n30 as has the smuggling of
    plutonium. n31 While the construction of a
    nuclear bomb is difficult, the U.S. Office of
    Technology Assessment has reported that it is
    definitely within the capabilities of a non-state
    group
  • A small group of people, none of whom have
    ever had access to the classified literature,
    could possibly design and build a crude nuclear
    explosive device. They would not necessarily
    require a great deal of technological equipment
    or have to undertake any experiments. The group
    would have to include at a minimum, a 250
    person capable of researching and understanding
    the literature in several fields and a
    jack-of-all trades technician. N32

14
Can terrorist acquire Nuclear Weapons? Some Say No
  • Gary Milhollin a Director of the Wisconsin
    Project on Nuclear Arms Controlcites cites
    several nuclear scientists who conclude that the
    risk is low.
  • There are essentially two ways for a terrorist
    group to lay its hands on a nuclear weapon
    either build one from scratch or somehow procure
    an already manufactured one or its key
    components. Neither of these is likely.
  • Building a bomb from scratch would confer the
    most power a group that could build one bomb
    could build several, and a nuclear arsenal would
    put it front and center on the world stage. But
    of all the possibilities, this is the
    unlikeliest-"so remote," in the words of a senior
    nuclear scientist at the Los Alamos National
    Laboratory, "that it can be essentially ruled
    out." The chief obstacle lies in producing the
    nuclear fuel-either bomb-grade uranium or
    plutonium-that actually explodes in a chain
    reaction. More than 80 percent of the effort that
    went into making America's first bombs was
    devoted to producing this fuel, and it is no easy
    task.
  • To make bomb-grade uranium, a terrorist group
    would need thousands of high-speed gas
    centrifuges, machined to exact dimensions,
    arranged in series, and capable of operating
    under the most demanding conditions. If they
    wanted to produce the uranium by a diffusion
    process, they would need an even greater number
    of other machines, equally difficult to
    manufacture and operate. If they followed Saddam
    Hussein's example, they could try building a
    series of giant electromagnets, capable of
    bending a stream of electrically charged
    particles-a no less daunting challenge. For any
    of these, they would also need a steady supply of
    natural uranium and a specialized plant to
    convert it to a gaseous form for processing.
  • Who would sell these things to would-be nuclear
    terrorists? The answer is nobody. The world's
    nuclear-equipment makers are organized into a
    cooperative group that exists precisely to stop
    items like these from getting into unauthorized
    hands. Nor could a buyer disguise the destination
    and send materials through obliging places like
    Dubai (as Iran does with its hot cargoes) or
    Malta (favored by Libya's smugglers). The
    equipment is so specialized, and the suppliers so
    few, that a forest of red flags would go up. And
    even if the equipment could be bought, it would
    have to be operated in a place that the United
    States could not find.

15
International Effort Against Nuclear Terrorism
  • Strengthening the Worldwide Effort The Nuclear
    Smuggling International Technical Working Group
    (ITWG) was chartered in 1996 to foster
    international cooperation in combating illicit
    trafficking of nuclear materials. The ITWG was
    formed with the recognition that nations must
    work together, says geochemist David Smith of
    the Nonproliferation, Homeland and International
    Security Directorate. The ITWG was cofounded by
    Livermore scientist Sid Niemeyer and has been
    cochaired by Lawrence Livermore since its
    inception. The ITWG works closely with the
    International Atomic Energy Agency (IAEA) to
    provide member countries with support for
    forensic analyses. Priorities include the
    development of common protocols for the
    collection of evidence and laboratory
    investigations, organization of forensic
    exercises, and technical assistance to requesting
    nations. Experts from participating nations and
    organizations meet annually to work on issues
    concerning illicit trafficking of nuclear
    materials. The 2006 meeting was sponsored by the
    European Commissions Institute for Transuranium
    Elements in Karlsruhe, Germany. To promote the
    science of nuclear forensics within the ITWG, the
    Nuclear Forensics Laboratory Group was organized
    in 2004. In that year, Livermore scientists wrote
    a comprehensive description of a model action
    plan to guide member states in their own nuclear
    forensic investigations. The plan provides
    recommendations governing incident response,
    sampling and distribution of materials,
    radioactive materials analysis, traditional
    forensic analysis, and nuclear forensic
    interpretation of signatures. In 2006, the IAEA
    published the model action plan as a Nuclear
    Security Series Technical Document. Participating
    countries have adopted the plan and used it in
    their own nuclear forensics investigations.

16
Problems faced by Nuclear Forensics Today
  • Due to huge costs and insignificant funding,
    nuclear forensics has been restricted to only a
    few national and international labs. Most
    scientists have not yet had the chance to learn
    how to handle the proper chemicals in order to
    work in a lab. Also, the standards for collecting
    and examining evidence that is suspected of being
    of a nuclear smuggling is still developing.

17
Sources of Nuclear Materials
  • Nuclear materials can be placed into three
    categories.
  • Special Nuclear Materials (SNM)
  • IAEA categories of High Enriched Uranium (HUE),
    which includes the sub category of Weapons Grade
    Uranium (WGU) and Weapons Grade Plutonium (WGPu).
  • Reactor Fuel
  • IAEA categories of Low Enriched uranium (LEU),
    Reactor grade Plutonium (RGPu), Fuel Grade
    Plutonium (FGPu), and Mox Grade Plutonium (MGPu).
  • Commercial Radioactive Sources
  • Chemically purified sources that decay by the
    emission of alpha, beta, or gamma rays.

18
Expectations and Attributions of Forensics
Scientists
  • Determining how and where legitimate control of
    nuclear material was lost and tracing the route
    of the material from diversion through
    interdiction are important goals for any nuclear
    attribution. It is equally important to
    determine whether additional devices or materials
    that pose a threat to public safety are
    available on the black market. The answer to
    these questions depends on determining the
    source of the material and its method of
    production. Nuclear forensics provides essential
    insights into methods of production and sources
    of illicit radioactive materials. It is most
    powerful when combined with traditional methods
    of investigation, including intelligence sources
    and traditional detective work. Nuclear
    forensics can play a decisive role in
    attributing and prosecuting crimes involving
    radioactive materials. Some of the current
    limitations of nuclear forensics are a result of
    the emerging nature and increasing urgency of
    this discipline. For example, the worlds
    nuclear powers are only now beginning to share
    information about their nuclear processes and
    materials. Numerous databases exist in many
    countries and organizations that could be
    valuable for the future development and
    application of nuclear forensics. The contents
    of many of these databases will never be directly
    shared, but the development of a distributed
    comprehensive database (see Section 6.3) will
    benefit international efforts. In addition,
    countries are beginning to combine the expertise
    of traditional forensics experts, normally found
    in police organizations, and nuclear experts,
    normally found in universities and government
    laboratories. Nuclear forensics will always be
    limited by the diagnostic information inherent in
    the interdicted material. For example, the
    clever criminal can minimize or eliminate the
    important markers for traditional forensics
    (fingerprints, stray material, etc.). Some
    nuclear materials inherently have isotopic or
    chemical characteristics that serve as
    unequivocal markers of specific sources,
    production processes, or transit routes. Other
    nuclear materials do not. Fortunately, the
    international nuclear engineering enterprise has
    a restricted number of conspicuous process steps
    that makes the attribution process easier.
    Finally, it will always be difficult to
    distinguish between materials that reflect
    similar source or production histories, but are
    derived from disparate sites.
