Exposure Units Flashcards
Exposure in air is measured in:
(R) roentgen or (Gy) gray this is the same as air KERMA
Absorbed dose is measured in:
rad or (Gy) gray or J/kg
Effective dose is measured in:
rem or (Sv) sievert
Radioactivity is measured in:
(Ci) Curie or (Bq) bequerel
Air KERMA is measured in:
Gy or J/kg
SI unit for absorbed dose is:
(Gy) Gray
SI unit for Effective dose is:
(Sv) Sievert
SI unit for radioactivity is:
(Bq) Bequerel
Air KERMA is measured in what unit?
Joule (J)- joule = c/kg
(Coulomb per kilogram)
What does KERMA stand for?
Kinetic Energy Released in Matter
What does ESE stand for?
Entrance Skin Dose
What does MMD stand for?
Mean Marrow Dose and it cannot be measured directly
What does DAP stand for?
Dose Area Product
How is patient dose measured in Fluoroscopy?
It’s measured during the exam using a DAP meter
