RADT 146 C - UNIT 6: Personnel Radiation
Protection (2) Questions with100% Correct
Answers
ALARA
As Low As Reasonably Achievable
-the basis of radiation protection: producing quality radiographic images while keeping radiation
exposure (operator, staff, patient) to a bare minimum
linear non-threshold
assumes that there is no minimum threshold of exposure necessary to achieve a biological effect
greatest threat of operator exposure
scatter radiation coming from patient and equipment (x-ray table top, Bucky tray, or leakage
radiation coming from tube housing)
irradiation
x-rays only occur when the unit is activated
protective barrier provisions
-operator must stand in the control area behind protective barrier during exposure
-a window (for viewing) having similar attenuation properties must be provided
-maintain a line of communication with patient
requirements for operator exposure
, -stand as far as practicable (6ft) from the scattered radiation source
-wear appropriate protective apparel
-use personnel monitoring device
protective aprons, gloves, goggles, and thyroid shields
-0.25 mm (Pb) equivalent to attenuate 97% of scattered radiation
-MUST be hung properly to prevent cracking of material
all resources, means, devices, and other tools
must be exhausted before a patient is held
guidelines for individuals who are occupationally exposed to radiation
-hold only during in an emergency, NOT to be done routinely
-must wear appropriate shielding devices
-positioned so that no part of the operator's body will be struck by the useful beam
-must wear personnel monitoring device outside of the apron, collar level
-involve a parent is possible, preferably the disciplinary one
**students
shall not be permitted to hold patients
**strictly forbidden
deliberate exposure of an individual for training or demonstration purposes
personnel monitoring devices
