Level 1 ASNT
- ANS-
The half-lifestyles of a co-60 source is ANS-five.3 years. A curie is the equal of: - ANS-1
000 mCi
A densitometer is an device for measuring: - ANS-film density
ANS-transform X-ray electricity into visible or ultraviolet light on a fluorescent intensifying
display When figuring out the kilovoltage to apply while X-raying a component, the following
trendy rule is regularly used: ANS—the kilovoltage have to be as low as other factors will
permit. A graph showing the relation among material thickness, kilovoltage, and publicity is
known as: - ANS-an publicity chart
The radiographic technique's ANS-high-quality is measured with a penetrometer. Although
there may be different motives for using calcium tungstate displays in business radiography
they're most customarily used to: - ANS-decrease publicity time
Under the given publicity conditions, the movie is located 36 inches (91 cm) faraway from
the X-ray tube's target for an extraordinary radiograph. The new exposure time can be
handiest approximately 25% longer than the original exposure time if the film is now best 46
centimeters (18 inches) from the target and all other publicity situations are maintained. An
brilliant radiograph is received under given publicity conditions with a tube cutting-edge of
five ma and an exposure time of 12 mins. What would be the required exposure time if other
conditions remained unchanged and the X-ray tube contemporary will be elevated to 10ma?
- ANS-6 mins Any of the body tissues may be injured by using excessive publicity to X- or
gamma rays but in particular sensitive are: - ANS-blood, lens of the attention, inner organs
As a test on the adequacy of the radiographic method, it us customary to area a fashionable
test piece at the supply side of the specimen. This widespread test piece is known as a: -
ANS-penetrometer
ANS-X-rays with a shorter wavelength and greater penetrating power are produced as the
kilovoltage carried out to the X-ray tube will increase. If an awesome radiograph is acquired
in 40s at a milliamperage of 10ma, how long wouldn't it take to attain an equal one at a
milliamperage of 5 ma (all other situations final regular)? ANS-80s Co-60 utilized in
nondestructive testing emits: - ANS-gamma rays
Excessive publicity of movie to mild prior to improvement of the film will maximum possibly
bring about: - ANS-a foggy film
Exposure to X-rays or gamma rays: - ANS-may have a cumulative impact which need to be
considered
Fluorescent intensifying monitors are usually hooked up in pairs in inflexible holders called: -
ANS-cassettes
For best results while manually processing movie, solution should he maintained within a
temperature range of: - ANS-18 to 24 C (sixty five to 75 F)
The following are most likely the reasons of frilling or loosening of the emulsion from the
base of the film: ANS-warm or exhausted fixer answer If a film is located in a developer
answer and allowed to increase without any agitation,: - ANS-there will be a tendency for
areas to affect every other
