Placed within the cassette and exposed to x-ray.

A

X-ray Film

23
Q

Functions of Films

A

Image Recording, Display, and Storage

24
Q

A rectangle or square plastic or metallic container used to hold x-ray films and intensifying screens.

A

Cassette

25
Q

A type of electromagnetic radiation that emanates from within the nuclei of radioactive atoms and are used to image the distribution of radiopharmaceuticals.

A

Gamma Rays

26
Q

A type of electromagnetic radiation that produced in detecting x and gamma rays; used for the observation and interpretation of images.

A

Visible Light

27
Q

A type of electromagnetic radiation that produced outside the nucleus and used in radiography and computed tomography.

A

X-rays

28
Q

A type of electromagnetic radiation used as transmission and reception signal for magnetic resonance imaging (MRI)

A

Radiofrequency

29
Q

A type of x-ray radiation that has higher frequency that the near-ultraviolet region of spectrum.

This type of radiation can alter molecules and cause harm.

A

Ionizing Radiation

30
Q

A type of radiation that has low-energy and does not remove electrons from atoms.

A

Non-Ionizing Radiation

31
Q

Two types of x-rays

A

Non-mobile and Mobile

32
Q

Provide an appropriate standard of protection for man without limting beneficial practices of radiation exposure.

A

Radiation Protection

33
Q

3 main principles of Radiation Protection.

A

Justification, Optimization of Protection, and Dose Limitation.

34
Q

Was the primary body created to advance for the public to benefit the science of radiological protection.

A

ICRP

35
Q

An estimate of the uniform, whole body equivalent dose that would produce same level of risk for adverse effects that results from the non-uniform radiation.

A

Effective Dose

36
Q

What is the unit use for Effective Dose?

A

Sievert (Sv)

37
Q

Describes the amount of radiation travelling through the air

A

Unit of Exposure

38
Q

Energy deposited in a tissue by the radiation beam per unit mass of matter.

A

Absorbed Dose

39
Q

What is the unit use for Unit of Exposure?

A

Roentgen (R) and Coulumb/kilogram (C/kg)

40
Q

What is the unit used for Absorbed Dose?

A

Gray (Gy)

41
Q

What is the recommended of radiation for people working with radiation every five years?

A

0.10 Sv

42
Q

Annual dose limit for radiation workers.

A

20 mGy

43
Q

typical dose for CT scan of chest?

A

10 mGy

44
Q

a type of effect that is due to cell changes (DNA) and proliferation towards a malignant disease.

A

Stochastic Effect

45
Q

a type of effect that is due to cell killing and have a close threshold-typically several Gy.

A

Deterministic Effects

46
Q

It is used as a protection for radiation.

A

Lead Shields

47
Q

In this view, the patient is able to stand or do an upright positioning.

A

PA View

48
Q

In this view, patient is not able to stand up or position in an erect, upright positioning.

A

AP View

49
Q

This type of view is used to confirm a particular abnormality that is seen in the initial chest PA/AP view.

A

Lateral View

50
Q

This type of view is used when a suspicious density is seen in the upper lung area of the chest PA view.

A

Apicolordotic View

51
Q

This type of view is used to confirm if the density seen in the chest PA/AP view is fluid or not.

A
