CBP Test 7 Study Guide Verified Exam Graded A+.

the CBP radiation detection program was created to detect and identify - correct answer materials, commodities, components CBP radiation detection program - correct answer to detect and prevent illicit radioactive materials from entering the US or from being moved away from the border areas within the US radiation detection devices - correct answer RPM, RIID, PRD, Radseeker LSSD - correct answer 1. laboratories and scientific services directorate 2. provides technical assistance and guidance to officers dealing with radioactive materials what is radiation? - correct answer radiation is energy in motion, in the form of particles and/or electromagnetic waves 2 types of radiation - correct answer non-ionizing and ionizing (both occur naturally, but can also come from man-made sources) NORM - correct 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 - correct answer alpha, beta, gamma or x-ray, neutron atoms are made up of - correct answer protons, neutrons, and electrons radionuclide - correct 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? - correct answer radioactive MATERIALS CBP uses the following units to measure radiation - correct answer rem, dose and dose rate rem - correct answer the most commonly used unit for measuring radiation dose (ex. the amount of energy you absorb) dose - correct answer the amount of biological damage (health effects) produced by radiation dose rate - correct answer the rate at which you receive the radiation dose over a period of time radiation doses - correct answer chronic and acute chronic dose - correct answer small doses of radiation received over a long period of time (body is able to repair cellular damage over time) acute dose - correct 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 - correct answer not more than 100 mRem and not more than 50 uR/hour how do you keep yourself safe from radiation? - correct answer keep exposure "As Low As Reasonably Achievable" (ALARA) ALARA techniques - correct 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 - correct 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) radiological weapons - correct answer 1. improvised nuclear devices (INDs) 2. Radiological dispersal devices (RDDs) 3. Radiological exposure device (REDs) improvised nuclear device (INDs) - correct answer use special nuclear materials and require sophisticated skills to build radiological dispersal device (RDDs) - correct answer "dirty bombs", use conventional explosives or alternative dispersal devices along with radiological materials radiological exposure device (REDs) - correct answer involves hiding a source near unsuspecting individuals, exposing them over time radiation detection program directive - correct 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 - correct answer practice SIN (secure, isolate, notify) gamma alarm response - correct answer 1. SIN, always notify supervisor 2. if documentation, and RIID identifications are not consistent with the common innocent radiation sources checklist, contact LSSD neutron alarm response - correct 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? - correct answer an RDD (dirty bomb) what is your required response when there is a neutron alert? - correct answer contact LSSD the purpose of risk targeting in the passenger-processing environment is to identify and eliminate: - correct 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 risk targeting resources - correct answer TECS, biometrics, ATS, APIS data, ATS-QQ, teams, technology, SIMGA/targeting framework (TF) TECS - correct 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) - correct answer is used by specialized targeting teams for passenger analysis an targeting risk targeting resources: teams - correct 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 - correct answer 1. personal radiation detectors 2. NII technology which risk targeting resource should be used when TECS is unavailable? - correct answer ATS-QQ to identify high-risk targets, you must be familiar with - correct 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 identifying high risk targets: land border - correct answer at a land border port, officers need to know surrounding cities to determine if the crossing location is logical given the origination and destination points
