Which of the following information is needed when calculating the effective dose for an exposure? Absorbed dose Dose area product Weighting factor of the radiation Weighting factor of the tissue

The effects of radiation on biologic material are dependent on several factors. If a quantity of radiation is delivered to a body over a long period of time, the effect

In the Compton interaction, to dislodge an outer-shell electron from its atomic orbit, the incoming x-ray photon must be able to transfer a quantity of energy:

A dose-response curve that could be used to represent the severity of biologic effects from radiation once a certain level of radiation was reached is said to be:

Any wall that the useful x-ray beam cannot be directed toward is call a

For which of the following diagnoses is an ERCP a useful procedure?  biliary tract calculi  patency of the biliary ducts  diverticula in the colon

Which type of radiation is produced when a high-speed electron is slowed down or suddenly stopped?

Methods of decreasing patient exposure during fluoroscopic procedures include:  position the image intensifier as far from the patient as possible  use the last image hold feature  use the largest FOV without magnification

The source of electrons within the x-ray tube is a result of
