RADS 306 Chapter 5

Three different filters are incorporated into the detector packet of the optically stimulated luminescence dosimeter. Of what are these filters made?

• Aluminum, tin, and copper

• • Aluminum, tin, and lead

• Zinc, copper, and barium

• Zinc, copper, and lead

What is the maximum period of time that a thermoluminescent ring dosimeter (TLD) may be worn as a personnel device?

• 1 hour

• 1 week

• 1 month

• 3 months

What do optically stimulated luminescence dosimeters, thermoluminescent ring dosimeters, and personnel direct ion storage dosimeters have in common?

• These devices are all used for area monitoring.

• These devices all use the same sensing material to detect ionizing radiation.

• These devices are all used for personnel monitoring.

• Each of these devices can only be used for personnel monitoring for a maximum of 6 months.

Which of the following instruments is called a cutie pie?

• • Geiger-Műller survey meter

• Ionization chamber-type survey meter

• • Optically stimulated luminescence dosimeter

• Proportional counter

Which of the following instruments generally has a check source of a weak, long-lived radioisotope located on one side of its external surface to verify its constancy daily?

• Personnel direct ion storage dosimeter

• Proportional counter

• Geiger-Műller survey meter

• Ionization chamber-type survey meter

Which of the following devices contains an aluminum oxide detector?

• Personnel direct ion storage dosimeter

• Optically stimulated luminescence dosimeter

• Proportional counter

• Thermoluminescent ring dosimeter

Which of the following are disadvantages of the TLD ring dosimeter?

• Thermoluminescence readings will be lost if not carefully recorded

• The readout process destroys information stored in the TLD ring dosimeter, thus preventing the “read” from serving as a permanent legal record of exposure.

• Calibrated dosimeters must be prepared before-hand and read with each group of TLDs as they are processed.

• All of the options.

When changing employment, what must a radiation worker convey to his/her new employer?

• A list of all fluoroscopic procedures performed daily

• A list of all radiographic procedures performed daily

• Data pertinent to accumulated permanent equivalent dose to be placed on file

• A report of all procedures performed when “on call” after regular hours

Three different filters are incorporated into the detector packet of the optically stimulated luminescence (OSL) dosimeter. These filters are respectively made of
1. aluminum.
2. copper.
3. molybdenum.
4. rhenium tungsten.
5. tin.

• 1, 2, and 3 only

• 1, 2, and 4 only

• 1, 2, and 5 only

• 2, 4, and 5 only

Whenever the letter “M” appears under the current monitoring period or in the cumulative columns of a personnel monitoring report, it signifies that a (an)

• mistake has been made in recording the equivalent dose.

• • equivalent dose higher than the minimum measurable radiation quantity was recorded during that time.

• equivalent dose below the minimum measurable radiation quantity was recorded during that time.

• maximal equivalent dose has been exceeded during that time.
