Effective protective measures take into consideration1. both human and environmental physical determinants.2. technical elements.3. procedural factors.

All of the following function to reduce patient dose, except

The operation of personnel radiation monitoring devices can depend on which of the following? 1. ionization 2. luminescence 3. thermoluminescence

The photoelectric effect is more likely to occur with  1. absorbers having a high Z number 2. high energy incident photons 3. positive contrast media

An ionization chamber connected to an electrometer is a device that can measure

Radiation that passes through the tube housing in directions other than that of the useful beam is termed

Why is a question concerning the amount of radiation a patient will receive during a specific x-ray procedure difficult to answer?1. Because the received dose is specified in a number of different units of measure2. Because the scientific units for radiation dose are normally not comprehensible by a patient3. Because the patient should not receive any information about radiation dose

THe production of x-ray photons by the sudden deceleration of high speed electrons is termed:

Calculation of equivalent dose (EqD) requires: 1. absorbed dose  2. type of radiation 3. tissue exposed

Which of the following terms is correctly used to describe x-ray beam quality?
