As Low As Reasonably Achievable
What does the inverse square law state
A)The intensity of radiation is inversely proportional to the square of the distance from the source of radiation
B)The intensity of radiation is measured at 6’ from the primary source which is where the interventional technologist should stand during procedures
C)Intensity should be expressed in coulombs per kilogram (C/kg).
