X-ray
s travel in straight lines but when they react with matter secondary
radiation is produced. In the
EZx,
all primary
X-ray
s are contained
within the machine. Secondary radiation (scatter) is also generated
however the penetration power of this radiation is greatly reduced.
The design of the
EZx
ensures any leakage from the machine is well
within international guidelines. The secondary radiation increases as the
X-ray
power level is increased so the minimum power level to give good
results for product inspection should be used.
The
EZx
has been designed to meet and exceed all current and relevant
safety regulations in relation to the use of
X-ray
s, with particular regard
to operator safety. The mechanical aspects of the system must not be
modified in any way without prior consultation with
Thermo Fisher
Scientific
.
WARNING. Abuse or modification of the equipment may result in
a serious danger to operators or maintenance staff. ▲
The UK safety level relating to the exposure for members of the public
to ionizing radiation is currently set at 1.0 microsieverts per hour. The
US safety level rating is 5.0 microsieverts per hour.
Thermo Fisher
Scientific
equipment is engineered to emit radiation levels below these
figures.
Safety limits in countries other than these may actually be higher than
this limit however;
Thermo Fisher Scientific
manufactures all of their
equipment regardless of market place to comply with these standards.
The
EZx
has been designed with operator safety in mind. The
X-ray
energies produced by the machine are contained within the machine to
UK and International regulations. Provided the machine is used in its
proper manner and warning labels strictly adhered to, then the machine
is perfectly safe to use.
As stated earlier, the acceptable maximum dose radiating from any point
of the
EZx
must be less than 1.0 microsieverts per hour. The current
safely limit for total annual exposure for unclassified personnel (which
is you as a normal citizen) is currently 5000 microsieverts per year. A
registered radiation worker (for instance a
Thermo Fisher Scientific
Engineer) is allowed 10 times this dose as an acceptable safe level of
exposure. The radiation survey meter (an optional purchase for the
EZx)
verifies exactly how small the emissions from the machine really are.
