Main property of x-radiation that makes it potentially hazardous is its ability to? - Ionize Describe the damage potential of ionization? - Chain reaction in the human body that may eventually cause biologic damage. X-rays are from the Electric Magnetic Spectrum or radiation energy and is considered harmful in high energy ranges. What is the most likely potential hazard working with diagnostic radiology? - Carcinogenesis - Stochastic/Non-Threshold Effect .1 Rem = ? Seivert - 1 Sievert ...

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...

Ionizing Radiation - radiation that is able to remove electrons from an atom through ionization Somatic effects - refers to the effects of radiation to the body being irradiated Genetic Effects - refers to effects of radiation to a germ cell's genetic code; effects the next generation Primary radiation - radiation exiting the x-ray tube Remnant radiation (or Exit Radiation) - x-rays the leave the patient and strike the image receptor attenuation - absorption and scatter of the x-ray beam ...
