be high
The effects of radiation that are directly related to the dose received, which can occur
months or years after exposure are called
Give this one a try later!
late stochastic
Radiographers must limit the patient's exposure to ionizing radiation by
1. employing appropriate radiation reduction techniques.
2. using protective devices that minimize radiation exposure.
3. selecting radiographic exposures factors that only use low kVp and high mAs
