Chapter 7. Shielding Installation
Installation and start-up of radiometric measuring systems may
be carried out only by persons who have been instructed ade-
quately by professional personnel!
Work is carried out under the guidance and supervision of the ra-
diological safety officer. It has to be ensured that the lock of the
shielding is closed.
Damage on the shielding must be avoided.
The shielding should be positioned as closely as possible to the
container surface.
The radiation danger sign has to be installed very close by to the
shielding.
The controlled area, if there is one, has to be identified and, if
necessary, secured.
How to calculate the radiation exposure during installation of the
shielding is described on page 101.
The user has to be familiar with the radiation protection guidelines
in Chapter 11.
Especially for measuring points with Super-Sens detector, the
shielding should be installed only after the zero count rate has
been determined, since the residual radiation from the shielding
(even if the shielding is closed) may distort the measurement of
the zero count rate.
