Infection Control |
Prevent spread of infections |
|
Medical Asepsis |
Freedom from infection Reduces # of pathogens PDI wipes Wash hands 20-30 seconds Use Purel or ETOH-based hand sanitizer |
|
Surgical Asepsis |
Complete freefom from infection Zero pathogens Wash hands for 8 minutes |

|
Radiation Biology |
Field of clinical and basic medical sciences that involves the study of the action of ionizing radiation on living things, especially health effects of radiation. |
|
Electromagnetic Spectrum |
Gamma Rays X-rays UV Lights Visual Spectrum IR Radio |
|
Sources of Ionizing Radiation |
Natural: -cosmic -food/water -radon -ground Manmade: -medical/dental -nuclear energy -video monitors/smoke detectors -tanning beds -microwave ovens -nuclear fallout |
|
Possible Interactions of X-rays w/ matter |
Classical/Thomson Photoelectric Compton Pair Production Photodisintegration |
|
Interaction of X-rays with matter: Classical/Thomson |
Low energy x-rays Excite & annoy patient's atoms Filtered out by Al++ on X-ray tube No energy transferred to patient |
|
Interaction of X-rays with matter: Photoelectric |
Inner shell electron is hit and ejected from orbit Outer shell electrons drop down to fill hole Greatest HAZARD to patient |
|
Interaction of X-rays with matter: Compton |
Outer shell electrons is hit and ejected & sent in another direction Reaches IR (clouding image) Reaches radiographer |
|
Interaction of X-rays with matter: Pair Production/Photodisintegration |
Does not occur in diagnostic imaging energies |
|
Radiation Untis of measure |
Gray/rad Sievert/rem Becquerel/curie |
|
Radiation Untis of measure: Gray/rad |
Radiation absorbed Energy absorbed by any medium |
|
Radiation Untis of measure: Sievert/rem |
Expresses the biological response to the quantity of different types of energy of radiation |
|
Radiation Untis of measure: Becqerel/curie |
Measures the rate of radioactive decay Used to calculate half-lives |
|
NCRP effective dose limits |
Public annual dose: 0.5 rem Fetus monthly: 0.05 rem Occupational exposure: -annual: 5 rem -cumulative: 1 rem x age |
|
Direct Hit Theory |
Any radiation transfers its energy to the molecule it has struck, resulting in changes |
|
What possible outcomes can happen to a cell? |
DNA/Direct -kills cell -break phosphate bonds -looses/rearranges genetic information Organelles & Cytoplasm/Indirect -Ionizes water -injures or kills cells -results in chemical changes |
|
Cellular sensitivity |
Bergonie/Tribondeau -cells are most sensitive during division -cells are most sensitive if primitive --stem cells --non-differentiated cells Ancel and Vietemberger -all cells are equally sensitive -all cells are most sensitive during active division -rapidly diving cells demonstrate injury sooner & appear to be be more sensitive |
|
ALARA |
As Low As Reasonably Achievable |
|
Time |
Reduce the amount of time patient is exposed |
|
Distance |
Maximize distance between human and xray tube |
|
Shielding |
Use whenever shield won't interfere with anatomy |
|
Radiation Effects: Stochastic |
Skin Erythema dose Local Tissue damage Lifespan shortening Leukemia/cancer Pregnancy effects |
|
Radiation Effects: Deterministic |
Effects that will happen at certain doses of radiation Occurs at high doses only Skin: Ulceration, Erythema Gonads: Female- Menstruation, Infertility, Sterility Male- Testicular atrophy, Infertility |
