RADIATION PROTECTION AND PROTECTIVE MEASURES Flashcards
(27 cards)
these are the 2 sources of ionizing radiation
NATURAL ENVIRONMENTAL/BACKROUND RADIATION AND HUMAN-MADE RADIATION
what happens to background radiation on areas with high altitude
BACGROUND RADITION BECOMES HIGHER
cosmic radiation from the sun and stars
BACKGROUND RADIATION
fallout from nuclear weapons testing and effluents from nuclear power plants
HUMAN-MADE RADIATION
radioactive elements on earth like uranium, radium & thorium
BACKGROUND RADIATION
radioactive materials used in the industry
HUMAN-MADE RADIATION
radioactive substances like radio potassium and radiocarbon which are found in foods, drinks, water and air
BACKGROUND RADIATION
medical and dental x-ray exposures
HUMAN-MADE RADIATION
this is the Radiologic Technologist’s responsibility
UNDERSTAND THE CHARACTERISTICS OF RADIATION POSSIBL BIOLOGIC EFFECT, AND METHOD OF REDUCING EXPOSURE OF PATIENTS AND OPERATOR
Radiologic Technologist’s goal:
MINIMAL RADIATION EXPOSURE AND OPTIMAL DIAGNOSTIC INFORMATION
ALARA
AS LOW AS REASONABLY ACHIEVABLE
ALADA
AS LOW AS DIAGNOSTICALLY ACHIEVABLE
formula in computing technical factors for patients
Tx2=C
this device is used to measure the body part thickness of the patient
CALIPER
enumerate ways to protect patient from unnecessary radiation
PROPER CALIBRATION OF EXPOSURE FACTORS; FILTRATION; COLLIMATION; AVOIDING REPEAT EXPOSURES; USAGE OF SHIELDING DEVICES
this is a radiation detection device used for personal dose monitoring or to measure patient dose
THERMOLUMINESCENT DOSIMETER (TLD)
a radiation measuring device wherein the amount of light absorbed is commensurate with the amount of radiation absorbed by the body
OPTICALLY STIMULABLE LUMINESCENT DOSIMETER (OSLD)
the maximum participle exposure radiation of an RT annually
50 mSv
the maximum participle exposure radiation of the general public annually
5 mSv
a non-profit corporation composed of scientific committees
NATIONAL COUNCIL ON RADIATION PROTECTION AND MEASUREMENTS (NCRP)
responsible for nuclear power production and radioactive material
ATOMIC ENERGY COMPOSITION (AEC)
responsible for environmental radiologic health protection
ENVIRONMENTAL PROTECTION AGENCY (EPA)
center for device regulation, radiation health and research
PHILIPPINE NUCLEAR RESEARCH INSTITUTE (PNRI)
the very first CT scanner
