Deterministic
CORRECT ANSWER
radiation-induced health effects where the severity increases with the dose, above a certain threshold
skin burns, hair loss, acute radiation syndrome
Stochastic
CORRECT ANSWER
Cancer causing effects, higher dose than deterministic effects
Exposure to Patient
CORRECT ANSWER
Minimal exposure for imaging and test, therapies increase risk of exposure
All must be approved by FDA for use
Practicing ALARA can reduce exposure to the patient
Exposure to technologist
CORRECT ANSWER
,Regular exposure occurs, practicing ALARA reduces exposure, monitoring badges and following
occupational exposure rates monthly is important
Short term effects of radiation
CORRECT ANSWER
High levels of radiation can lead to short term effects such as Acute Radiation Sickness (ARS) or
Cutaneous Radiation Injury (CRI)
Long term effects of radiation
CORRECT ANSWER
Often from treatments - not imaging, long term exposure to high amounts of radiation
Effects can be:
Increased Cancer Risk
Heart and Lung Problems
Endocrine Issues
Cognitive and Neurological Effects
Musculoskeletal and Soft Tissue Problems
Reproductive Issues
Eye and Vision Problems
Acute Radiation Sickness (ARS)
CORRECT ANSWER
also known as radiation sickness, occurs following a significant exposure to ionizing radiation, usually
over a short period
, Cutaneous Radiation Injury (CRI)
CORRECT ANSWER
refers to skin damage resulting from high-dose radiation exposure
Radiosensitivity (effects on the cell)
CORRECT ANSWER
response of the tumor to irradiation that can be measured by the extent of regression, rapidity of
response, and response durability
radiation kills cells by inhibiting their ability to divide
ALARA (time)
CORRECT ANSWER
the amount of time spent with a dose the great the exposure
for ALARA it is important to reduce the time spent with the dose to reduce exposure
ALARA (distance)
CORRECT ANSWER
inverse square law
ALARA (sheilding)
CORRECT ANSWER
Half-value Layers (HVL)
CORRECT ANSWER
radiation-induced health effects where the severity increases with the dose, above a certain threshold
skin burns, hair loss, acute radiation syndrome
Stochastic
CORRECT ANSWER
Cancer causing effects, higher dose than deterministic effects
