Long Quiz (MIDTERM) Flashcards
The device commonly used to measure radiation exposure and provide a record of the dose receive.
DOSIMETER
The term that refers to the measurement and calculation of radiation dose received by an object or tissue.
DOSIMETRY
The unit of measurement for the absorbed dose of radiation in tissue, commonly used in dosimetry.
mGyt
Refers to a light-sensitive layer used in film and photographic materials, composed primarily of silver halide crystals suspended in a gelatin matrix.
PHOTOGRAPHIC EMULSION
It is used as IR in digital imaging system.
SCINTILLATION DETECTION
Specific type of gas-filled detector that operates by collecting ion pairs created by radiation and is commonly used for measuring low levels of radiation.
IONIZATION CHAMBER
Refers to a type of radiation detector that measures ionizing radiation by the ionization of gas within a chamber.
GAS-FILLED DETECTORS
Give at least one materials of scintillation detection.
CsI:TI or NaI:TI
It is us or contamination control in nuclear medicine laboratories.
GEIGER-MULLER COUNTER
Main type of radiation that a Geiger-Müller counter is commonly used to detect, including alpha particles, beta particles, and gamma rays.
IONIZING RADIATION
Refers to a type oof radiation detector that measures ionizing radiation by detecting the ionization events with a gas filled chamber, providing a proportional output signal
PROPORTIONAL COUNTER
It has the ability to distinguish between alpha & beta radiation
PROPORTIONAL COUNTER
It is used in the detectors arrays of CT imaging system.
SCINTILLATION DETECTION
Refers to a type of dosimeter that measures ionizing radiation by trapping energy in a crystalline material and releasing it as light upon heating.
THERMOLUMINESCENCE DOSIMETRY (TLD)
Identify the specific type of materials commonly used in TLDs, which are sensitive to radiation and capable of storing energy.
LITHIUM BORATE, LITHIUM FLUORIDE, CALCIUM SULFATE, CALCIUM FLUORIDE
A chart of curves from which one can estimate the output intensity of radiographic unit.
NOMOGRAM
It use as a personnel monitoring, stationary & area monitoring.
THERMOLUMINESCE DOSIMETRY (TLD)
A type of dosimeter that measures ionizing radiation by trapping energy in a material and releasing it as light when stimulated by optical radiation.
OPTICALLY STIMULATED LUMINESCENCE DOSIMETRY (OSL)
Material commonly used in OSL dosimeters, which is known for its sensitivity to ionizing radiation.
ALUMINUM OXIDE
The radiation dose received by the skin at the point of entrance during a medical imaging procedure.
ENTRANCE SKIN DOSE (ESD)
The measurement unit commonly used to express entrance skin dose in radiology.
mGyt
Average gonadal dose given to members of the population who are of childbearing age.
GENETICALLY SIGNIFICANT DOSE (GSD)
Term that refers to the average dose of radiation received by the bone marrow from medical imaging procedures.
