DISTRIBUTION OF STRAY RADIATION

.
Note
30
Measurements conditions to determine the distribution of Stray Radiation in the
Significant Zone of Occupancy are in accordance with Standard
IEC60601-1-3:1994, 2008 and 2013:
Exposure Parameters RAD mode: 150 kVp, 10 mAs, 50 mA.

Collimator opening for Field Size 18 x 18 cm, at SID 50 cm and 100 cm.

Phantom: Rectangular water phantom of 25 x 25 x 15 cm, or a material

having a similar X-Ray attenuation coefficient.
Radiation measuring instrument: Low Radiation Dosimeter.

The results have been obtained with a configuration that is
representative of the worst case within the different configurations
of the unit.
Refer to Illustration 2-1 for Receptor in Vertical position and refer to
Illustration 2-2 for Receptor in Horizontal position.
The following illustration shown the Distribution of Stray Radiation in each
examination position, where:
DISTANCE TO CENTRAL X-RAY BEAM
SID
50 cm
100 cm
In order to obtain the Distribution of Stray Radiation to distances greater than
1000 mm, the radiation decreases with the square of the distance.
