3 / 12

How is contamination detected in a portal monitor?

It sounds a musical tone

It lights up in a specific color

It alarms and indicates which detectors are in alarm

It sends a wireless notification to a control room

4 / 12

How should one hold the probe of a portable frisker for beta/gamma radiation surveys?

Approximately ½" from the surface

Directly on the surface

Approximately 3" from the surface

Approximately 5" from the surface

6 / 12

In which order are radiation monitors preferred for exiting a radiologically controlled area?

WBCM, frisker, and then PM

PM, WBCM, and then frisker

WBCM, PM, and then frisker

Frisker, WBCM, and then PM

7 / 12

What is the main purpose of a Whole Body Contamination Monitor (WBCM)?

To provide initial entry screening for radiological areas

To identify damaged radioactive equipment

To detect the source of radiation in the environment

To self-monitor for contamination prior to exiting a radiologically controlled area

8 / 12

Which contamination monitor uses an array of gas flow proportional detectors?

Whole-body contamination monitors (WBCMs)

Portable friskers

Tool Equipment Monitors (TEM)

Portal monitors

9 / 12

What type of device is a portal monitor?

A wearable device

A handheld device

A drone-type device

A "door frame" type device

10 / 12

What happens if an individual exceeds alarm set points in a WBCM?

The WBCM informs the individual that they are contaminated

The individual is immediately quarantined

The individual is promoted to a higher security level

The WBCM shuts down for maintenance

11 / 12

What is the primary use of Tool Equipment Monitors (TEM)?

Track radiation sources in a facility

Communicate with radiological control authorities

Monitor small hand-held items for release from radiologically controlled areas

Monitor large facilities and structures

12 / 12

What might be a consequence of not performing an adequate contamination survey?

Immediate decontamination of equipment

Increased morale among workers

Spread of contamination

Decreased radiation levels in the area
