Gray
Ans: The SI unit of the absorbed dose is the:
Relative biological effectiveness
Ans: Is a term used to compare the effects of radiation
on living systems:
80%
Ans: What percentage of a cell is water?
Tunica Fibrosa
Ans: What is the protective layer of the eyeball, or globe?
The lubricating effects of blinking
Pretest - Stuvia US
,2
Ans: What is an orbital defense against infection?
1-2 weeks
Ans: Older, damaged cells of the corneal epithelium are
shed from the eye during blinking or tearing. The cells is
this layer are repopulated how often?
1. Fiber cells contain more cholesterol than any other
than any other cell in the human body.
2. Fiber cells produce crystallin, a protein that helps
determine how well the lens refracts light.
3. The loss of fiber cells contributes to the formation of
cataracts.
Ans: What 3 things are true about the fiber cells of the
lens?
Neuron ganglia
Ans: Which structures trigger aversion reflexes when
potentially dangerous intense light hits the retina?
Pretest - Stuvia US
,3
Photoreceptor Transduction
Ans: What is the process by which rod and cone cells
transform light energy into nerve impulses?
What are characteristics of deterministic radiation
effects?
Ans: 1. The severity of damage to tissue is dose
dependent.
2. A dose threshold exists such that the probability of
damage from low doses is negligible.
True
Ans: True or false: radiation-induced cataracts can result
from a single high dose or from chronic low-dose
exposure of the lens, which is why occupational exposures
over time represent a major concern for fluoroscopy
operators.
Linear no-threshold
Pretest - Stuvia US
, 4
Ans: The as low as reasonably achievable (ALARA)
principle is based on what model?
10
Ans: Children are up to how many times more sensitive to
tissue and DNA damage from ionizing radiation than are
adults?
5% per Sv
Ans: The risk of any radiation-induced cancer from a
single fluoroscopic exam is what percent per Sv?
Sebaceous Carcinoma
Ans: According to the article, which cancer of the eyelid
has been linked to ionizing radiation and ultraviolet
sunlight?
Keratitis
