Customs and Border Protection Test 7 Study Guide with
Practice Questions
1. the CBP radiation detection materials, commodities, components
pro- gram was created to
detect and identify
2. CBP radiation detection program to detect and prevent illicit radioactive
materials from
entering the US or from being moved away
from the border areas within the US
3. radiation detection devices RPM, RIID, PRD, Radseeker
4. LSSD 1. laboratories and scientific services directorate
2. provides technical assistance and guidance
to ofl- cers dealing with radioactive materials
5. what is radiation? radiation is energy in motion, in the form of
particles and/or electromagnetic waves
6. 2 types of radiation non-ionizing and ionizing (both occur naturally,
but can also come from man-made
sources)
7. NORM naturally occurring radioactive material (NORM)
can be detected in many commodities:
1. natural potassium in granite tiles
2. uranium and thorium in soils
8. types of ionizing radiation alpha, beta, gamma or x-ray, neutron
9. atoms are made up of protons, neutrons, and electrons
10. radionuclide refers to a radioactive atom that MAY not be an
ISO- TOPE of an element, but is still unstable
11. what source of radiation is CBP most concerned about?

12. CBP uses the following units rem, dose and dose rate
to measure radiation
13. rem the most commonly used unit for measuring
radiation dose (ex. the amount of energy you
absorb)
14. dose the amount of biological damage (health ettects)
pro- duced by radiation
15. dose rate the rate at which you receive the radiation dose
over a period of time
16. radiation doses chronic and acute
17. chronic dose small doses of radiation received over a long
period of time (body is able to repair cellular
damage over time)
18. acute dose 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 ettects may occur with acute
doses as low as 25 Rem
19. CBP occupational does limits not more than 100 mRem and not more than 50
uR/hour
20. how do you keep yourself safe from keep exposure "As Low As Reasonably
Achievable"
radiation? (ALARA)
21. ALARA techniques time: keep exposure times as short as
