2.11 DETERMINISTIC EFFECTS
Deterministic effects may occur when the Radiation dose to a certain organ or
tissue exceeds a specific threshold. Particular organs or tissues of such
concern in diagnostic Radiology are the skin and the eye lens. The numerical
value of the threshold dose is in the range between 1 Gy and 3 Gy.
As shown in the Quantitative Information Tables, the radiation dose effects
measured in this equipment are below the threshold in which the severity of
certain effects would take place on human skin or eyes lens.
This mentioned threshold was established by the International Commission on
Radiological Protection (ICRP Publication No 60).
Quantitative Information tables (Refer to Section 2.10) illustrate examples of
available loading factors for image performance and supply Dose indication,
which affect to the radiation quality or to the radiation dose rate applied in
normal use.
As indicated in the Quantitative Information Tables, the number of exposures
needed to reach the previously described maximum radiation values will
depend on the selected techniques for each radiographic study.
