Danger!
The M1 ORA/MISTRAL spectrometer system is an analytical instrument with a
strong X-ray source. Shielding and safety equipment guarantee that the
emitted radiation does not exceed 1.0
μ
Sv/h during operation.
Shielding and safety features designed into the equipment guarantee that the emitted radiation
does not exceed 1.0 µSv/h (at 5 cm from any external surface of the device) during operation. This
level is below the regulatory limit in all jurisdictions. The ICRP dose limits in Publication 60 and
103 to the whole body for a radiation worker averaged over a 5-yr period is 20 mSv in a year, and
for a member of the public it is 1 mSv in a year. It is highly unlikely that the radiation worker dose
limits will be exceeded when trained and qualified personnel use such devices.
Read the section ‘Safety Instructions’ of this manual (chapter 2) before turning on the system.
Please observe local regulations for the operation of X-ray systems.
If you suspect that the safety system does not work correctly or that radiation protection is impaired
for any reason, immediately switch off the system and contact your local Bruker Service
Representative. Manipulations and modifications of the safety systems are strictly forbidden!
Note
The X-ray generator is controlled by a two position Keyed switch (OFF/ON)
similar to the ignition switch of a car. The key can only be removed when the
switch is in the OFF position. The switch will remain in the OFF position until
the key is inserted and turned. Therefore the removal of the key will terminate
production of X-ray.
