Medical physicists use ionization chambers connected to electrometers to perform the annual standard measurements required by state, federal, and health care accreditation organizations for radiographic and fluoroscopic devices. These annual measurements include1. x-ray output in Gy or mGy.2. fluoroscopic radiation entrance rates in mSv/min.3. kVp setting accuracy.4. exposure time exactness.5. half-value layers, or beam quality

The largest amount of diagnostic x-ray absorption is most likely to occur in which of the following tissues?

Factors that contribute to the amount of scattered radiation produced include 1. radiation quality 2. field size 3. grid ratio

Which of the following is a form of radiation that is capable of creating electrically charged particles by removing orbital electrons from the atom of normal matter through which it passes?

Potential ionizing radiation damage to tissue is dependent on the  1.Z number if the tissue 2. type of ionizing radiation 3. mass density of the tissue

Which of the following is not a type of interaction between x-radiation and biologic matter?

For exposure to 10 mGy of each of the following radiations, which would result in the greatest dose to the individual?

The advantages of the BERT method are 1. it does not imply radiation risk; it is simply a means for comparison.2. it emphasizes that radiation is an innate part of our environment.3. it provides an answer that is easy for the patient to comprehend.

Electromagnetic radiation travels or propagates through space in the form of a wave but can interact with matter as a particle of energy called a photon. This dual nature is referred to as

Which of the following results in all-directional scatter?
