RADIOBIOLOGY RADT 155 EXAM 1
REVIEW
Adding or removing an electron from atom is called __________. - ANS-ionization
measures an air kerma - ANS-Roentgen
ionization in the air is called __________ - ANS-air kerma
What are the 3 cardinal rules? - ANS-Time, distance, shielding
How do we know about radiobiology? - ANS--Early Inventors & Physicians
-Uranium Miners
-Radium Dial Painters
-Military operations
-Hiroshima/Nagasaki
Who is Catherine Donohue (1938)? - ANS-A radium dial painter, ate radium dust and
had ended up dying
Name 3 reasons why we study Radiobiology? - ANS--Better understanding of radiation
protection
-Enhance perspectives of profession
-Basis for radiation oncology
Radiobiology - ANS-The study of the effects of ionizing radiation on living matter
Who was Madam Marie Curie? - ANS-a physicist and chemist that conducted
pioneering research on radioactivity
Who was Henry Becquerel? - ANS-He discovered evidence of radioactivity like
fluorescence
Who was Ernest Rutherford? - ANS-English physicist who studied how positively
charged alpha particles interacted with solid matter
-Thorium properties
, Who was Dr. Daniels Vanderbilt? - ANS-He discovered hair loss due to radiation
exposures
Who was Dr. Leopold Freund? - ANS-He discovered radiotherapy treatment
Who was Clarence Daly? - ANS-He was noted as an assistant to Thomas Edison in his
work on X-rays and as an early victim of radiation dermatitis and its complications
What are the potential effects of radiation exposure with atomic molecular interactions?
- ANS--Can have no effect
-Sublethal damage
-Immediate effect
-Delayed Effect
With sublethal damage effect what happens? - ANS--From this damage, it goes to
repair and then back to normal
With immediate effect after atomic molecular interaction, what happens? - ANS--From
this effect it leads to cell death or loss of normal function, and then goes to repair, and
then back to normal
With delayed effect after atomic molecular interaction, what happens? - ANS-From this
effect it goes to the latent period, then to cell death or loss of function, to repair, and
then back to normal
What are the 5 effects? - ANS-1. cellular level
2. molecular level
3. tissue
4. organs
5. body systems
Part dose vs. Whole body - ANS-Part dose affects every cell
Whole body effects the molecule exposed
Cancer - ANS-Abnormal cells that causes malfunctions
-can be benign or malignant
Atom - ANS-smallest particle of an element that has all of its chemical properties
Molecule - ANS-smallest unit of specific substance
