Radiograph with many light and dark areas, but FEW shades of grey is said to have.... - High contrast



few shades of gray with high contrast is prooduced with------kVp - low kvp



increasing mA alone results in a film with - increased density



film produced using 90 kVp and 0.25 seconds. what exposure time is needed to produce the same at 75
kVp ? - 0.50 seconds



The total energy contained in the xray beam in a specific area at a given time is termed.... - intensity



Increasing these will increase the intensity of the x-ray beam? - kVp, mA, and exposure time



The HVL is the amount of.. - Aluminum needed to reduce the x-ray beam intensity by half.



The kVp range for most dental x-rays is - 65-100 kV



A higher kVp produces x-rays with - more penetrating ability



Radiation produced with high kVp results in - short wavelengths



increasing mA results in an increase in - Temp of filament and number of x-rays produced



the mA range for dental radiography is - 7 to 15 mA



Thermionic emission occurs in the - negative cathode

, which radiation accounts for 70% of all the x-ray energy produced at the anode? - General radiation



Which radiation occurs only at 70 kVp or higher ad accounts for a very small part of dental x-rays
produced? - Characteristic radiation



Primary radiation best described as - radiation exists the tubehead



Which type of scatter happens most often with dental x-rays? - Compton



why is an increased target film distance required in the paralleling technique? - to avoid image
magnification



"Thin transparent coating that is placed over the emulsion." - protective layer



" flexible piece of plastic that withstands heat, moisture and chemical heat" - film base



Chemical compounds that change when exposed to radiation or light are termed - halides crystals



invisible pattern of stored energy on the exposed film is termed? - latent image



Purpose of a lead foil sheet in the film packet is: - to protect film from back scattered radiation



The -----the crystals, the -------- the film speed - The larger the crystals , the faster the film speed



What regulates the flow of electrical current to the filament of the x-ray tube? - low -voltage circuit



What is used to increase the voltage in the high -voltage circuit? - step-up transformer
