the CBP radiation detection program was created to detect and identify - Answer
materials, commodities, components
CBP radiation detection program - Answer to detect and prevent illicit radioactive
materials from entering the US or from being moved away from the border areas
within the US
LSSD - Answer 1. laboratories and scientific services directorate
2. provides technical assistance and guidance to officers dealing with radioactive
materials
what is radiation? - Answer radiation is energy in motion, in the form of particles
and/or electromagnetic waves
2 types of radiation - Answer non-ionizing and ionizing (both occur naturally, but can
also come from man-made sources)
NORM - Answer naturally occurring radioactive material (NORM) can be detected in
many commodities:
1. natural potassium in granite tiles
2. uranium and thorium in soils
types of ionizing radiation - Answer alpha, beta, gamma or x-ray, neutron
atoms are made up of - Answer protons, neutrons, and electrons
radionuclide - Answer refers to a radioactive atom that MAY not be an ISOTOPE of
an element, but is still unstable
what source of radiation is CBP most concerned about? - Answer radioactive
MATERIALS
CBP uses the following units to measure radiation - Answer rem, dose and dose rate
rem - Answer the most commonly used unit for measuring radiation dose (ex. the
amount of energy you absorb)
dose - Answer the amount of biological damage (health effects) produced by
radiation
dose rate - Answer the rate at which you receive the radiation dose over a period of
time
radiation doses - Answer chronic and acute

Solutions.
chronic dose - Answer small doses of radiation received over a long period of time
(body is able to repair cellular damage over time)
acute dose - Answer large dose of radiation received in a short period of time
1. much more dangerous than chronic dose
2. body may become overwhelmed and unable to repair damage to cells
3. biological effects may occur with acute doses as low as 25 Rem
CBP occupational does limits - Answer not more than 100 mRem and not more than
50 uR/hour
how do you keep yourself safe from radiation? - Answer keep exposure "As Low As
Reasonably Achievable" (ALARA)
ALARA techniques - Answer time: keep exposure times as short as possible
distance: keep your distance as far as possible from source
shielding: increase the mass between yourself and the source
radiation exposure distance - Answer doubling the distance from a radiation point
source reduces the amount of exposure by 75% (if you move double your distance
away from the source, you reduce your exposure by FOUR times)
improvised nuclear device (INDs) - Answer use special nuclear materials and require
sophisticated skills to build
radiological dispersal device (RDDs) - Answer "dirty bombs", use conventional
explosives or alternative dispersal devices along with radiological materials
radiological exposure device (REDs) - Answer involves hiding a source near
unsuspecting individuals, exposing them over time
radiation detection program directive - Answer 1. all officers issued a PRD are
required to carry it while on duty
2. detain person or item when alarm is activated
3. verify the alarm and locate the source
4. all alerts must be resolved per CBP radiation detection standard operating
procedures directive
how to respond to a radiation alert - Answer practice SIN (secure, isolate, notify)
gamma alarm response - Answer 1. SIN, always notify supervisor
2. if documentation, and RIID identifications are not consistent with the common
innocent radiation sources checklist, contact LSSD

Solutions.
neutron alarm response - Answer 1. always notify supervisor
2. isolate the source (SIN ESTABLISH A PERIMETER)
3. confirm and verify the presence of neutrons
4. LSSD must be contacted for resolution of all neutron alarms
what type of radiological device are terrorists most likely to use? - Answer an RDD
(dirty bomb)
what is your required response when there is a neutron alert? - Answer contact
LSSD
the purpose of risk targeting in the passenger-processing environment is to identify
and eliminate: - Answer first: potential threats to the US and its interests related to
terrorist activities and instruments of terror
second: violations of national security, narcotics, currency, and other laws enforced
by CBP
TECS - Answer 1. lookouts on specific persons and businesses
2. arrest warrants from the NCIC
3. access to intel alerts/reports and summaries of seizures and arrests nationwide
4. the crossing history of vehicles and people at the land border and person at
airports
5. drivers licenses and registration information related to the conveyance
6. past inspection results
7. criminal records
automated targeting system (ATS) - Answer is used by specialized targeting teams
for passenger analysis an targeting
risk targeting resources: teams - Answer passenger analysis units (PAUs), counter
terrorism response (CTR), anti-terrorism contraband enforcement team (A-TCET),
canine enforcement teams, tactical analysis units (TAU's), advance targeting units
(ATU's), national targeting center (NTC)
risk targeting resources: technology - Answer 1. personal radiation detectors
2. NII technology
which risk targeting resource should be used when TECS is unavailable? - Answer
ATS-QQ
to identify high-risk targets, you must be familiar with - Answer 1. world geography,
known source countries, typical travel routes, trends and previous seizures
2. MOST IMPORTANTLY, know the travelers and travel patterns typical for your port
