RADS 306 Chapter 1

Regarding exposure to ionizing radiation, patients who are educated to understand the medical benefit of an imaging procedure are more likely to

• suppress any radiation phobia and be willing to assume a small chance of possible biologic damage.
  

• suppress any radiation phobia but not risk a small chance of possible biologic damage.
  

• assume a small chance of biologic damage but not suppress any radiation phobia they may have.
  

• cancel their scheduled procedure because they are not willing to assume a small chance of biologic damage.

The advantages of the BERT method are
1. BERT does not imply radiation risk; it is simply a means for comparison.
2. BERT emphasizes that radiation is an innate part of the environment.
3. BERT provides an answer that is easy for the patient to comprehend.

• 
  1 and 2 only

• 
  2 and 3 only

• 
  1 and 3 only

• 
  All the options

If a patient asks a radiographer a question about how much radiation he or she will receive from a specific x-ray procedure, the radiographer can

• refuse to answer the question and recommend that he or she speak with the referring physician.
  

• tell the patient that it is unethical to discuss such concerns.

• 
  avoid the patient’s question by changing the subject.

• respond by using an estimation based on the comparison of radiation received from the x-ray to natural background radiation received.

Which of the following is a method of explaining radiation to the public?

• 
  ORP

• ALARA

• 
  NEXT

• 
  BERT

The millisievert (mSv) is equal to

• 
  1/10 of a sievert.

• 1/100 of a sievert.

• 
  1/1000 of a sievert.

• 
  1/10,000 of a sievert.

In a hospital setting, which of the following professionals is expressly charged by the hospital administration with being directly responsible for the execution, enforcement, and maintenance of the ALARA program?

• 
  Student radiologic technologist

• • Radiation Safety Officer
    

• Chief of staff

• Assistant administrator of the facility
  

Which of the following provides the basis for determining whether an imaging procedure or practice is justified?

• 
  ALARA concept

• BERT method

• Diagnostic efficacy

• NEXT program

Which of the following radiation quantities is intended to be the best overall measure of the biologic effects of ionizing radiation?

• There is no radiation quantity that is intended to be the best overall measure of the biologic effects of ionizing radiation.

• 
  Absorbed dose

• 
  Exposure

• 
  Effective dose

The term as low as reasonable achievable (ALARA) is synonymous with the term

• diagnostic efficacy.

• 
  equivalent dose (EqD).

• optimization for radiation protection (ORP).

• background equivalent radiation time (BERT).

What is the SI Unit of measure for EfD?
