Section 3 Installation
3.1 General Safety Precautions
The shielding with the radioactive source is delivered in a box in
compliance with the regulations concerning transportation of ra-
dioactive substances.
Take the shielding out of the box just prior to installation.
Up to that time, store it in a location that is guarded against
unauthorized access.
Using the drawings of the shielding and taking into account the
situation at the measuring site, carefully install the mounting
brackets and fixings. Make sure that the mechanical stability of the
mounting devices matches the weight of the shielding. The shield-
ing should be assembled just prior to taking the system into opera-
tion.
Secure all screws and fixing parts, so that they cannot come
undone during operation, and the shielding cannot fall
down.
To keep the radiation exposure of the assembling personnel as low
as possible, only licensed personnel who have been trained on how
to handle radioactive substances are allowed to assemble or disas-
semble the shielding with the source.
The work is performed according to the instructions and under the
supervision of the Radiation Safety Officer. It has to be ensured
that the lock of the shielding is closed and secured, so that no un-
shielded radiation can exit. Make sure the shielding is not modified
or damaged.
Very important! Please read the Radiation Protection Guide-
lines in Section 12 Radiation Protection and observe them
exactly!
The radiation exit channel must always be closed during in-
stallation!
