A beam of radiation consisting of a unmarried wavelength is referred to as: -
ANS-monochromatic radiation
The half of lifestyles of a supply of Co-60 is: ANS-five.Three Years. A curie is the equivalent
of how many mCi - ANS-1,000 mCi
A densitometer is an device for measuring: - ANS-movie density
a fluorescent intensifying display screen will: - ANS-rework x-ray strength into seen or
ultraviolet light
A general rule often hired for figuring out the Kilovoltage for use while x-raying a component
is that: - ANS-the Kilovoltage have to be as little as other factors will allow
a graph showing the relation between fabric thickness, Kilovoltage, and exposure is called: -
ANS-an exposure chart
A graph which expresses the connection among the logarithm of the publicity carried out to
a photographic material and the resulting photographic density is called: - ANS-the
characteristic curve
a big supply size can be compensated for by means of: - ANS-growing the
source-to-specimen distance
a penetrameter is used to suggest the: - ANS-great of the radiographic method
A ANS-radiograph is a photographic photograph that is recorded on movie through passing
x- or gamma rays through a specimen. A well exposed radiograph that is evolved for five
mins in a developer answer at 58 levels Fahrenheit will in all likelihood have: ANS
underdeveloped ANS-growing kilovoltage can be used to reveal a phase with a good sized
boom in thickness variant on a single radiograph within the favored movie density range. A
sheet of lead with a gap reduce in the form of the component to be radiographed may be
used to lower the impact of scattered radiation which undercuts the specimens. This kind of
tool is referred to as a: - ANS-masks
a thin metal sheet (brass, copper, aluminum, etc..) positioned on the source to reduce
effects of softer radiation is referred to as: - ANS-a filter
Although there may be other reasons for the use of calcium tungstate monitors in industrial
radiography, they are most usually used to: - ANS-Decrease publicity time
an advantage of the pocket dosimeter sort of ionization chamber used to reveal radiation
obtained by way of employees is: - ANS-it affords a right away indication of dosage
After six half of-lives, approximately how a lot of the authentic radioactivity remains? -
ANS-2 As a take a look at on the adequacy of the radiographic technique, it is normal to
vicinity a popular take a look at piece on the source aspect of the specimen. This
widespread test piece is known as a: - ANS-penetrameter
ANS-x-rays with a shorter wavelength and more penetrating electricity are produced
because the Kilovoltage implemented to the x-ray tube will increase. Atoms, molecules, and
numerous subatomic particles that carry both a wonderful or bad electrical rate are known
as: - ANS-ions
beta debris are: - ANS-electrons
, When utilized in nondestructive trying out, Co-60 releases the subsequent radiation: in the
course of guide movie processing, the reason of the prevent bathtub is to: - ANS-neutralize
the developer and stop the growing method
excessive exposure of movie to light previous to improvement of the movie will most
probable bring about: - ANS-a foggy movie
Exposure to x-rays or gamma rays can have what impact at the frame? - ANS-It might also
have a cumulative effect which should be considered
Fluorescent intensifying displays are typically established in pairs in inflexible holders called:
- ANS-Cassettes
fluoroscopy differs from radiography in that: - ANS-the x-ray image is found visually on a
fluorescent screen rather than recoded on film
When manually processing movies, answers must be stored among ANS-sixty five and 75
degrees Fahrenheit for first-class outcomes. Frilling or loosening of the emulsion from the
bottom of the film is most probable because of: - ANS-heat or exhausted fixer solution
gamma and x-radiation engage with be counted and may be absorbed via: (3) -
ANS-photoelectric absorption, Compton scattering and pair manufacturing
If a movie is placed in a developer solution and allowed to increase with none agitation: -
ANS-There can be a tendency for areas to have an effect on each different
if a piece of lead half" thick is located inside the route of a beam of radiation emanating from
Co- 60, it will lessen the dose rate at a given place by means of: - ANS-One- half
In film radiography, pentrameters are typically located: - ANS-at the supply side of the take
a look at item
so one can achieve uniformity of development over the area of an x-ray film for the duration
of manual processing: - ANS-the movie should be agitated while in the developer
In order to decrease geometric unsharpness: - ANS-Radiation must proceed from as small
a focal spot as other issues will allow
In order to increase the depth of the x-radiation: - ANS-the tube modern-day ought to be
improved
in x-radiography, the ability to penetrate the test item is governed with the aid of: -
ANS-kilovoltage
The most controllable x-ray exposure elements are kilovoltage, publicity time, and the gap
from the source to the movie. ANS-milliamperage is the fourth such exposure thing. Lead foil
in direct contact with x-ray movie: - ANS-Intensifies the primary radiation more than the
scatter radiation
lead displays in touch with the movie throughout exposure: - ANS-extended the
photographic motion on the film in large part by means of cause of the electron emission and
in part by the secondary x-rays generated within the lead
ANS-unsharpness is influenced by means of 3 elements: motion, geometry, and screen
touch. One in all the general guidelines regarding the utility of geometric standards of
shadow formation to radiography is: - ANS-the space among the anode and the material
tested must constantly be as tremendous as viable
one requirement for preserving fluorescent monitors in proper situation is they ought to: -
ANS-not be uncovered to extreme ultraviolet radiation
penetrameters for ____________ are taken into consideration Group I substances and do
no longer need to have an identity notch - ANS-chrome steel
primary radiation which strikes a movie holder or cassette via a skinny part of the specimen
will cause scattering into the shadows of the adjacent thicker portions generating and effect
called: - ANS-undercut
A beam of radiation consisting of a unmarried wavelength is referred to as: -
ANS-monochromatic radiation
