Example: Calculation radiation dose

Exposure with U = 70 kV, Q = 20 mAs and source to skin distance, r = 1.05 m:
From Diagram 1, read the corresponding value of Y for U= 70 kV:
2 /mAs
Y = 37 µGy x m
The radiation dose D is calculated with Equation (2):
2 /mAs) x 20 (mAs) / (1.05) 2 = 671 µGy
D = 37 (µGy x m
The radiation dose at a distance of 1.05 m with tube voltage 70 kV and 20 mAs is
D= 671 µGy.
