What does area monitoring measure?

The area or what is emitted from the machine.

What is area monitoring used for?

To test equipment to measure output.

Is area monitoring used to measure dose to people?

No, it is not used to measure dose to people.

What type of monitor is used for area monitoring?

Ionization chamber type survey monitor (cutie pie).

Who uses area monitoring equipment and for what purpose?

Used by the physicist to measure what’s happening with the equipment — exposure rate and cumulative exposure.

What types of radiation does area monitoring measure?

X-ray radiation, gamma radiation, and beta radiation.

What applications is area monitoring especially good for?

Fluoroscopic applications and radioactive isotopes.

Where is the Geiger-Müller (GM) detector primarily used?

In nuclear medicine facilities.

What does the sensitivity of the GM detector allow?

Detection of individual particles.

What is the GM detector good for detecting?

Areas of contamination.

What type of dosimeter is worn as a second monitor during procedures requiring hands near the primary x-ray beam?

A thermoluminescent dosimeter (TLD) ring badge.

Purpose of the extremity dosimeter

To measure radiation exposure to the hands during radiographic procedures.

What feature does the laser-etched cover of the TLD ring badge include?

Identification.

Is the TLD element of the dosimeter reusable?

Yes, it is a reusable TLD element.

Why is keeping a record of radiation exposure important?

To understand that there are different groups of people from other jobs that receive radiation. It provides perspective that imaging professionals’ exposure is not far from other main jobs involving radiation.

What does the record of radiation exposure help demonstrate?

That many precautions are taken to reduce the amount of exposure received.
