FUN 1 EO: 1.35 & 1.36

1 / 7

How does the OSL material in optically stimulated luminescent dosimeters (OSLDs) measure radiation?

Green light is emitted directly in response to incident radiation.

Electrons excited by radiation are trapped and released when stimulated by light.

Shielding of the crystals allows direct calculation of radiation type.

Electrons are heated to produce visible light.

2 / 7

Which of the following is an advantage of optically stimulated luminescent dosimeters (OSLDs)?

Requires heat to luminesce.

Allows for multiple readings to confirm reported doses.

Can only be read once.

More “fading” than TLDs.

3 / 7

What is a major disadvantage of thermoluminscent dosimeter (TLD) compared to optically stimulated luminescent dosimeter (OSLD)?

The OSLD has more fading than TLDs.

The TLD cannot be re-read after processing.

The TLD allows multiple readings.

The OSLD requires heat to luminesce.

4 / 7

Which of the following is a key concept in the ALARA philosophy?

The reliance on technology to reduce exposure.

The immediate effects of radiation on humans.

The reasonable cost associated with saving radiation exposure.

The creation of an unlimited budget for reducing exposure.

5 / 7

What is a typical dose range for secondary electronic personnel dosimeters?

Dose rate: 0 – 2000 rem/hr

Dose rate: 0 – 100 rem/hr

Dose 0 – 200 rem

Dose 0 – 1000 rem

6 / 7

If a station would like to install shielding at a cost of $60,000 to save 1 REM CRE, what would make the cost justifiable?

If the station's installation of shielding would have no cost.

If the station's installation of shielding would save 1 rem.

If the station's installation of shielding would save 4 rem.

If the station’s installation of shielding would cost $20,000.

7 / 7

What does the term 'acceptable risk' in regard to radiation protection limits mean within a power plant?

It represents the cost associated with saving 1 Rem of exposure.

It assumes there is a benefit such as power generation for an individual receiving dose.

It signifies the potential for immediate effects from radiation exposure.

It refers to the maximum amount of radiation allowed in a facility.
