1st 2 weeks
it is when major organogenesis happen, the major organ system of fetus is developing and its biological response will be congenital malformation
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)
