Radiation Health and Safety EXAM
A film by accident exposed to white light between growing and solving will appear -
ANS-dark
A movie that has been exposed to scattered radiation will seem - ANS-Fogged
A movie with thin density and a herringbone sample across it's miles the end result of: -
ANS-Film packet reversal
A complete mouth radiographic collection has just been processed manually. The operator
notes that the movies on the button of the rack are of different density. What ought to have
precipitated this? - ANS-Solutions had been no longer stirred before processing
A complete mouth radiographic survey has simply been processed manually. The pinnacle
films on the processing rack have a instantly, clear border at the top side. This errors is
caused by - ANS-Too low a stage of developer answer
A figure refuses for i have radiographs taken on his/her infant. The dental assistant should -
ANS-Inform the dentist and document Parent's refusal
A individual exposing x-rays can BEST be protected from scattered radiation by means of -
ANS-status in the back of a lead barrier
A radiograph turns brown over the years. The MOST in all likelihood motive is - ANS-Under
washing
A white inverted V-shaped radiopacity on the lowest of the film is maximum probably
resulting from - ANS-lead apron artifact
According to federal policies, the beam size ought to be now not exceed how many inches
on the sufferers pores and skin surface? - ANS-2 three/4
According to government recommendations, the every year even as body radiation dose for
occupationally exposed workers must no longer exceed - ANS-five rems (50 mSv)
Atoms the have lost electrons are known as - ANS-Ions
Before exposing a wide ranging radiograph on a affected person, the operator need to
request the elimination of all the following EXCEPT: - ANS-Watch
Bitewing films are commonly used to - ANS-Detect carries
, Bremsstrahlung (breaking radiation) is produced whilst electrons collide with the goal,
creating - ANS-Secondary radiation
Cephalometric radiographs are on the whole indicated to assess - ANS-Jaw relationships
Compared with x rays produced by way of a 70 kV dental x ray system, x rays produced by
using a 90 kV system are - ANS-More penetrating
Contrast on a dental radiograph can be altered via changing the - ANS-kilovoltage
Density of a radiograph is managed via all of the following EXCEPT - ANS-OFD [[object film
distance]]
During movie placement, the embossed dot of the movie packet must be located in the
direction of the occlusal or Incisal edges except for what exposures? - ANS-Bitewings
Film velocity is decided by way of the - ANS-Size of the silver bromide crystal
Filtration of the x ray beam protects the affected person through - ANS-Eliminating
vulnerable wavelength X-rays from the X-ray beam
Flaws or faults exhibited within the production of intraoral radiographs are because of what
sorts of mistakes - ANS-Exposure errors
Processing errors
Film managing
Film storage
For intraoral radiology, a double film packet is used to - ANS-Produce equal films with a
single publicity
Foreshortening of the radiographic photo whilst the usage of the bisecting perspective
technique (BAT) results from too - ANS-Much vertical angulation
Ideally, a lead apron could be used - ANS-For any dental radiographs
If a dental auxiliary's radiation badge file indicates publicity to small amounts of radiation,
what ought to be completed first? - ANS-evelauate the xray gadget and strategies
If all acknowledged radiation safety precautions are exercised, an operator who is pregnant
can appropriately disclose radiographs during the operator's - ANS-complete being pregnant
If tooth seem foreshortened on the authentic radiograph, the vertical angulation of the
principal beam for the retake is - ANS-Decreased
