open beam
Measur
ements of the main beam without a
sample (
open Beam) were collected at 5, 10, 30, and
100c
m. The result at the sample position was extrapolated from measured results using a semi-
log plot as described in IEC 62495. The main beam leaves the front of the instrument going
forward and up at a 45-degree angle. Locations where the intensity of the main beam falls to 10%
and 1% of the intensity at its center were recorded using the “Standard Setting 1 Alloy Phase 1”
only. See the following figure.
RadEye gives instantaneous results but is not accurate over large energy ranges. A second survey
of the main beam was done with 80 pkV, 2.9mm Al HVL NanoDots (TLD dosimeters) from
Landauer with a request to apply the correction factor for NIST H30 that most closely matches
the X-rays in the beam for the setting used.
The NanoDots were exposed at the locations defined with the RadEye at 10, 30 and 100cm
distances from the nose, for a measured time using the Standard Setting 1 Alloy Phase 1.
NanoDots do not give instantaneous results but are more accurate. The RadEye was used to find
the location of the center of the main beam. Its readings at that time were recorded so a
comparison of the results from the NanoDots and RadEye could be made.
