2nd - 10th weeks
it is when the principal response occurs which is malignant disease during childhood
2nd - 3rd trimester
3 administrative protocols in patient information
elective booking
patient questionnaires
posting
occupational radiation exposure dose limit
20 mSv/yr
it contributes to the highest occupational exposure of diagnostic x-ray personnel
fluoroscopy
it is best to position the x-ray tube _______ ___ ______ during mobile
& C-arm fluoroscopy
it is best to position the x-ray tube UNDER THE PATIENT during mobile
& C-arm fluoroscopy
personnel receive higher exposures due to longer fluoroscopic x-ray beam on time
interventional radiology
interventional radiology dose limit
500 mSv/yr
personnel exposures are low due to less scatter radiation due to low kVp operation
mammography
personnel exposures are low due to x-ray beam is finely collimated and only secondary radiation is present in the examination room
computed tomography
occupational exposure for nursing personnel & other working in the operating room & intensive care unit is near zero
surgery
it contributes to the highest occupational exposure of diagnostic x ray personnel
mobile radiology
the dose of radiation that would be expected to produce no significant radiation effects
maximum permissible dose (MPD)
maximum permissible occupational radiation dose
dose limit (DL)
it is specified only for occupational exposure
dose limit (DL)
