14Terrorism
- Is and always has been . . . a form of warfare.
15CASUALTY-PRODUCING ABILITIES
Selective Targets
16Terrorism
- Both the target and the type of weapon used are
chosen for a purpose.
17Psychological Effects
18Achieving victory in every battle is not absolute
perfection neutralizing an adversarys force
without battle is absolute perfection.

20Threat Levels
Imminent Threat Alert Warns of a credible,
specific, and impending terrorist threat against
the United States. Elevated Threat Alert Warns of
a credible terrorist threat against the United
States.

39Introduction to Radiation
- Review of Ionizing Radiation
- Review or Introduction to Dosimetry
- Deployment of the UltraRadiac
- Responding to a Dosimeter Alarm
40Nuclear/Radiological Incident
- General Information
- Radiation can be detected with meters
- Unlikely to find high levels distant from the
source - Use meters to determine isolation area
- Victims should not be sick or symptomatic on the
scene - Exposure only does not require immediate gross
decontamination
41Types of Ionizing Radiation
Provided by the Department of Energy, NsTec
42Potential Radioactive Sources
- Use of radiological material in a terrorist
attack. - Radiological Dispersal Device (RDD)
- Radiological Exposure Device (RED)
- Radiopharmaceuticals used in medicine
- Industrial sources
- Naturally occurring
43Nuclear/Radiological Incident
- Time, distance, and shielding are
- appropriate self-protective measures
- Equipment
Pancake Detector
RadWatch Dosimeter
Canberra UltraRadiac Radiation Monitor
FLIR nanoRaider
Ludlum Response Kit
44Ionization
- A physical change in an atom
- Caused by ionizing radiation
- Atom becomes electrically charged
- Occurs when electrons are removed from neutral
atoms - Ions or ion pairs are produced
45Ionizing Radiation
X-Rays
Gamma Rays
Beta Particles
Alpha Particles
Neutron Particles
46Radiation Penetration
- These three forms of radiation have a specific
mass and a specific energy value - These factors cause the forms to behave in
different ways
47Alpha Particles
48Beta Particles
49Gamma Rays X-Rays
Fission Products (Co-60, Ir-192, Cs-137
Radiography
50Neutron Particle
51Dosimetry
52Radwatch
- You will be issued a radwatch at the time of
deployment. - The radwatch will measure your radiation absorbed
dose during the deployment and must be worn
entire time. - The radwatch may be read during the deployment if
needed.
53Units of Measure
Roentgen (R) ionization of air by radiation
energy R per hour (R/hr) is used on radiation
survey meters
Radiation Absorbed Dose (Rad) a unit for
measuring absorbed dose in any material
54Units of Measure
- For gamma and x ray radiation, a common
conversion factor between exposure, absorbed
dose, and dose equivalent is - 1 R 1 rad 1 rem

59Incendiary Device Awareness and Response
60Incendiary Devices
- USR teams will likely encounter incendiary
devices during pre-positioned operations or as
secondary devices - The catastrophic effects of the
- 9-11 incendiary attacks.
61Common Formulations
- May include
- Molotov cocktail, ignitable liquids
- Napalm and/or Poor mans Napalm
- Thermite
- Pyrophoric chemicals, eg. white phosphorus
- Thickened Pyrophoric Agents (TPA)
62Incendiary Device Recognition
- Victims with diffuse thermal burns
- Widespread or unusually intense fire
- Chemical odors and containers or fragments
63Explosives
- High-intensity blast
- Secondary hazards
- Potential threats of additional devices
- Conditions likely to effect ops
64Why Target USR Personnel?
- Search and Rescue essential service
- Cause overwhelming fear in the public
- Delay search and rescue efforts
- Instill fear in other responders
65Summary
- Terrorist activities
- CBRNE Events that we may respond to
- Situational Awareness
