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
