HAZWOPER 40: Lesson 12 Quiz
1. Radiation personal sampling dosimeters::
2. Which term is defined as the ability of an instrument to detect and measure
a specific chemical or group of similar chemicals?: Selectivity
3. The interaction of the oppositely charged particles and the (blank) keep the
electrons in orbits outside the nucleus.: Laws of quantum mechanics
4. A contaminant reacts with the indicator chemical in the colorimetric indi-
cator tube, producing a change in color. The length of the colored area is
proportional to the:: Contaminant concentration
5. Since most monitoring instruments were designed for industrial use, al-
lowances may not have been made for using them while wearing:: Protective
equipment
6. When monitoring the atmosphere for air contaminants, one must evaluate
the reliability of the:: Resulting data
7. The safeguards that prevent combustion in a flammable atmosphere are
NOT designed to operate in which atmosphere?: Oxygen-enriched
8. Which monitor has the same limitations, considerations, and detection
method as CGIs?: Catalytic combustion detectors
9. An active sampling system should be calibrated both before and after a
prescribed sampling period.: True
10. Which of the following apply to active samplers?:
1/1
