Consequences of Ionization in Human Cells ii ii ii ii ii
1: Which of the following is a consequence of ionization in human cells?
ii ii ii ii ii ii ii ii ii ii ii ii
A) Production of stable atoms
ii ii ii ii
B) Creation of reactive free radicals capable of producing substances poisonous to the cell
ii ii ii ii ii ii ii ii ii ii ii ii ii
C) Decreased electron activity
ii ii ii
D) Prevention of new biologic molecule formation
ii ii ii ii ii ii
*Answer: B ii
Explanation:: Ionization in human cells creates unstable atoms, produces free electrons,
ii ii ii ii ii ii ii ii ii ii
ii generates low-energy x-ray photons, creates reactive free radicals that can produce cell-
ii ii ii ii ii ii ii ii ii ii ii
poisonous substances, creates detrimental new biologic molecules, and causes injury that may
ii ii ii ii ii ii ii ii ii ii ii
ii manifest as abnormal or loss of function. These six consequences are fundamental to
ii ii ii ii ii ii ii ii ii ii ii ii
ii understanding radiation-induced cellular damage. ii ii ii
2: When ionizing radiation passes through matter, it produces:
ii ii ii ii ii ii ii ii
A) Neutrons and protons
ii ii ii
B) Positively and negatively charged particles (ions)
ii ii ii ii ii ii
C) Only positively charged particles
ii ii ii ii
D) Only negatively charged particles
ii ii ii ii
*Answer: B ii
Explanation:: Ionizing radiation produces both positively and negatively charged particles (ions)
ii ii ii ii ii ii ii ii ii ii
,ii when passing through matter. These ions are the primary event that may cause injury in normal
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
ii biologic tissue, as the production of ions disrupts normal cellular function and structure.
ii ii ii ii ii ii ii ii ii ii ii ii
3: The production of ions in human cells is significant because it:
ii ii ii ii ii ii ii ii ii ii ii
A) Enhances cellular reproduction
ii ii ii
B) May cause injury in normal biologic tissue
ii ii ii ii ii ii ii
C) Increases cellular metabolism
ii ii ii
D) Prevents genetic mutations
ii ii ii
*Answer: B ii
Explanation:: The production of ions is the event that may cause injury in normal biologic tissue.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
ii This understanding forms the basis for radiation protection practices, as controlling ionization
ii ii ii ii ii ii ii ii ii ii ii
ii helps minimize potential cellular damage during imaging procedures.
ii ii ii ii ii ii ii
4: Radiologic technologists and radiologists minimize the possibility of causing damage to healthy
ii ii ii ii ii ii ii ii ii ii ii ii
ii biologic tissue by: ii ii
A) Increasing exposure time
ii ii ii
B) Using protective devices whenever possible
ii ii ii ii ii
C) Avoiding the use of technical exposure factors
ii ii ii ii ii ii ii
D) Standing close to the x-ray tube during exposures
ii ii ii ii ii ii ii ii
*Answer: B ii
Explanation:: Radiologic technologists and radiologists are educated in safe operation of
ii ii ii ii ii ii ii ii ii ii
ii radiation-producing equipment, use protective devices whenever possible, follow established ii ii ii ii ii ii ii ii
ii procedures, and select technical exposure factors that significantly reduce radiation exposure to
ii ii ii ii ii ii ii ii ii ii ii
ii patients and themselves. These good practices minimize the possibility of causing damage to
ii ii ii ii ii ii ii ii ii ii ii ii
ii healthy biologic tissue. ii ii
, 5: Which of the following best defines unnecessary radiation exposure?
ii ii ii ii ii ii ii ii ii
A) Any exposure that benefits the patient clinically
ii ii ii ii ii ii ii
B) Any exposure that does not benefit a person in terms of diagnostic information needed for
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
ii clinical management or does not enhance study quality
ii ii ii ii ii ii ii
C) Only exposure that exceeds 50 mSv per year
ii ii ii ii ii ii ii ii
D) Only exposure received from natural background sources
ii ii ii ii ii ii ii
*Answer: B ii
Explanation:: Unnecessary radiation exposure is defined as any radiation exposure that does not ii ii ii ii ii ii ii ii ii ii ii ii
ii benefit a person in terms of diagnostic information obtained for clinical management of medical
ii ii ii ii ii ii ii ii ii ii ii ii ii
ii needs or any radiation exposure that does not enhance the quality of the study. This definition
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
ii guides the ALARA principle in medical imaging.
ii ii ii ii ii ii
6: The ALARA principle stands for:
ii ii ii ii ii
A) As Long As Radiation is Avoidable
ii ii ii ii ii ii
B) As Low As Reasonably Achievable
ii ii ii ii ii
C) Always Limit Adult Radiation Amounts
ii ii ii ii ii
D) Annual License for Radiation Administration
ii ii ii ii ii
*Answer: B ii
Explanation:: ALARA is an acronym for "as low as reasonably achievable," which is synonymous ii ii ii ii ii ii ii ii ii ii ii ii ii
ii with optimization for radiation protection (ORP). The intention behind these concepts is to keep
ii ii ii ii ii ii ii ii ii ii ii ii ii
ii radiation exposure and consequent dose to the lowest possible level. This philosophy should be a
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
ii main part of every health care facility's radiation control program.
