Radiation Flashcards
When can skin injuries from radiation occur?
Fluoroscopy procedures
High radiation doses
What is non-ionizing radiation?
Does not have enough energy to remove electron s from atoms and molecules
It can heat substances
Ex. Microwave, lasers, tanning bed
Affects of non ionizing radiation on skin?
Burns
Aging
Eye damage
Skin cancer
What is ionizing radiation?
Kinetic energy
Can remove electrons from atoms abs molecules
Ex. X-RAY, CT, nuclear medicine
Radiation exposure can be reduced by following what 3 principles?
Time
Distance
Shielding
Documentation for radiation procedure?
Pre-op skin assessment
Safety measures
Dose of radiation
Post op skin assessment
Safety for radiation?
Lead aprons
Shielding
Dosimeter
Determine pregnancy status
What is ALARA?
As Low As Reasonably Achievable
What do dosimeters do?
Used to measure amount of radiation exposure
Wear under lead aprons
Always put in same spot
What is the main source of radiation of staff?
Scattered radiation from surface of patient
- always face radiation source
- lead aprons
- thyroid shield (increased sensitivity)
- time, distance, shielding
If you 2x your distance from radiation source how much does it decrease your exposure?
2x distance = 1/4 exposure
