HEALTH AND SAFETY HAZARDS
Marconi Applied Technologies magnetrons are safe to handle
and operate, provided that the relevant precautions stated
herein are observed. Marconi Applied Technologies does not
accept responsibility for damage or injury resulting from the use
of electronic devices it produces. Equipment manufacturers and
users must ensure that adequate precautions are taken.
Appropriate warning labels and notices must be provided on
equipments incorporating Marconi Applied Technologies
devices and in operating manuals.
High Voltage
Equipment must be designed so that personnel cannot come
into contact with high voltage circuits. All high voltage circuits
and terminals must be enclosed and fail-safe interlock switches
must be fitted to disconnect the primary power supply and
discharge all high voltage capacitors and other stored charges
before allowing access. Interlock switches must not be
bypassed to allow operation with access doors open.
RF Radiation
Personnel must not be exposed to excessive RF radiation. All
RF connectors must be correctly fitted before operation so that
no leakage of RF energy can occur and the RF output must be
coupled efficiently to the load. It is particularly dangerous to
look into open waveguide or coaxial feeders while the device is
energised. Screening of the cathode sidearm of high power
magnetrons may be necessary.
X-Ray Radiation
High voltage magnetrons emit a significant intensity of X-rays
not only from the cathode sidearm but also from the output
waveguide. These rays can constitute a health hazard unless
adequate shielding for X-ray radiation is provided. This is a
characteristic of all magnetrons and the X-rays emitted
correspond to a voltage much higher than that of the anode.
Whilst Marconi Applied Technologies has taken care to ensure the accuracy of the information contained herein it accepts no responsibility for the consequences of any
use thereof and also reserves the right to change the specification of goods without notice. Marconi Applied Technologies accepts no liability beyond that set out in its
standard conditions of sale in respect of infringement of third party patents arising from the use of tubes or other devices in accordance with information contained herein.
