shortest possible exposure time - the minimum response time of an automatic exposure control (AEC) (also called photo timing) inherent filtration (built in) - together, the filtering effect of the x-ray tube's glass envelope and its oil coolant are referred to as: periodic checks for cracks - proper care of leaded aprons includes: thermionic emission - the source of electrons with the x-ray tube is a result of: underexposed radiographic image - inadequate collimation when using the AEC ...

Manifest Production - 1. The period of time after an acute exposure to radiation in which effects of the exposure are seen is called Chromosone - The most radiosensitive part of a normal human cell is the Cataracts - A large radiation exposure to the lens of the eye will most likely result in the formation 3-5 Weeks - Death that follows an acute exposure to radiation of about 500 rems will generally occur in about indirect effect - 5. The majority of damage to the body from radiation expos...

what statements are correct regarding the link between radiation and genetic effects - The link has been demonstrated in animal studies . Increased risk to humans cannot be predicted with respect to an individual. The changes in kilovoltage (kVp) will result in the greatest reduction of patient dose, when milliampereseconds (mAs) is adjusted to compensate for the change - Increase kVp by 30% The following image receptor (IR) system speeds will result in the lowest patient dose - Faster speed...
