3. Safety Information

3.1 Radiation Safety Information
Olympus handheld XRF analyzers are secure and dependable instruments when used in accordance with recommended
testing techniques and safety procedures.
• Olympus analyzers must only be used by trained and authorized operators in accordance with proper safety
procedures. Improper use may impair safety protection and cause potential harm to the user.
• Read all warning signs and labels.
• DO NOT USE the instrument if there is any evidence of damage, as doing so could cause unintentional emission of
stray radiation. In such a case, arrange for qualified personnel to perform a radiation safety test and repair any
damage to the instrument.
3.2 Safety Interlock Structure
To control X-ray emissions, thereby minimizing the possibility of accidental exposure, the DELTA handheld XRF analyzer
has a standard safety interlock structure consisting of the three features listed below:
1. Software proximity sensor
Within one second of a test start, the analyzer detects the sample in front of the measurement window. If no sample is
detected the test aborts to prevent accidental exposure, the filter wheel goes to position 0, and the X-rays shut off. The
tube current is reduced to 0.0 μA, and the red light stops blinking. Also, if the probe/nose is pulled away from the
sample while a test is in progress, testing stops in approximately one second.
2. Software trigger lock
If five minutes elapse between tests (default time), the trigger automatically locks and you must tap on the Lock button
( ) to unlock it.
3. Safeguards
As an owner of an Olympus handheld XRF analyzer, your safeguards include those items indicated below:
• Limited access
Keep the instrument in a controlled location to which only trained and authorized users have access.
• Trained operators
Post a sign near the analyzer indicating that it must only be used by operators who have completed a training
class provided by your company, or who have attended an Olympus training course and completed any other
requirements stipulated by the local regulating authority. When the Olympus instrument is turned on, the user
interface screen displays a message indicating that the instrument should only be used by authorized personnel.
• Shielding issues
An Olympus handheld XRF analyzer emits a tightly collimated beam of X-ray radiation. Although attenuation
occurs, the beam may project many meters in open air.
Adequate shielding is achieved by:
— Establishing a no-admittance zone sufficiently distant from the instrument's measurement window to allow
air to attenuate the beam.
