Proper use
When th
e
instru
ment
is use
d properly, X
-ray radi
ation from instrument poses no harm to the user
or others.
Use the instrument for only its intended use.
Each
instru
ment
A radi
ation profile is measured on each
instru
ment before it leaves the factory.
Safe use
Safe use
of any XRF device is based on the principles of:
Princi
ple
Descript
ion
Time
Managing the amount of time during which X-rays are produced.
Distance

Keeping all parts of the user’s body as far away from the X-ray producing nose
as possible.
 Pointing the analyzer away from others.
 Keeping others away from the instrument during use.
Shield
ing

Ensuring that the instrument is mechanically intact and sound.
 When measuring small samples that might allow X-ray radiation to escape,
use a benchtop or desktop stand and close the lid.
ALARA
Collectiv
ely, these practices are known
as “As Low as
Reasonably Achievable” (ALARA). Safe
practice is further discussed during user training. For more details, see the Radiation Safety
Manual, Bruker document 030.0011.

2.1. Radiation Profile – S1 TITAN
Testing
standa
rds
The radi
ation profile reflects the radiological conditions during
worst-case (hig
h voltage, high
power)
instrument operation.
To establish radiation profiles –
 IEC 62495 (2011), Nuclear instrumentation – Portable X-ray fluorescence analysis
equipment utilizing a miniature X-ray tube was used as a guide.
 The analyzer was set at the maximum voltage and current established for analysis, with a
standard material sample over the examination window.
 Per the guide, measurement of stray radiation (leakage and scatter) was conducted at 1
0,
30, and 100 centimeter distances from the surface.
 Additionally, the geometric size of the X-ray beam and the open beam radiation d
ose
equ
ivalent rates were recorded at 0, 5, 10, 30, and 100 centimeters.
