Chapter 03: Radiation Characteristics Iannucci: Dental Radiography, 5th Edition MULTIPLE CHOICE 1. In dental radiography, the term ________ is used to describe the mean energy or penetrating ability of the x-ray beam. a. quality b. quantity c. intensity d. wavelength ANS: A Quality is used to describe the mean energy or penetrating ability of the x-ray beam. Quantity refers to the number of x-rays produced. Intensity is defined as the product of the quantity and quality per...

Rectification Constant - A value of the heat unit formula that varies depending on the generator used. Generators used in Radiography - single phase generator delivers pulsating x-ray beam (1), Three phase generator = 3 phase 6 pulse machine (1.35) , High frequency generator = 3 phase 12 pulse machine (1.41) Rectification - The rectifier of the x-ray tube changes alternating current (AC) to direct current (DC). This process ensures that the x-ray production flows in the right direction; fr...

Wilhelm Rontgen - Answer-Who discovered the X-ray? Decay damage, change in bone patterns, impacted teeth, cysts, and tumors - Answer-What can X-rays identify? Ionizing radiation - Answer-X rays are a form of what? Ionizing Radiation - Answer-We can't see or feel this energy but as it moves through the body, it disrupts atoms in its path, causing them to separate into ions Sickness, cancer, birth defects, and even death. - Answer-Too much ionization can cause what? FALSE. Radiat...

ALARA As Low As Reasonably Achievable If the operator cannot leave the room when exposing a radiograph, which of the following is considered the safest position for the operator to stand? Behind a lead barrier The MOST effective way to prevent the operator from x-radiation is to? Increase the distance from the source of radiation The principal source of exposure radiation for dental personnel is most likely to be? scattered radiation In the dental radiography, "M...

Radiation Protection Chapter 5 with Complete Solutions 2023 Position indicating device *ANS* Extension of the x-ray tubehead; is used to direct the x-ray beam Collimation *ANS* Used to restrict size and shape of x-ray beam and to reduce patient exposure MPD *ANS* Maximum doe equivalent that a body is permitted to receive in a specific period of time Beam alignment *ANS* A device that helps to stabilize the receptor position in the mouth and reduces the receptor position in the mouth ...
