2.6.1 Point source shielding 45°
Fig. 2-16 Radiation warning sign
Increased radiation dose due to open beam channel!
A too high dose of radiation may be harmful to your health.
A source may be transported only in its shielding. The shielding
must be closed during transportation and installation.
The shielding has a fan-shaped exit channel which emits radiation
towards the front and downward up to an angle of 45°. This allows
the shielding to be mounted vertically which simplifies the con-
struction of the fixing bracket and the installation the shielding,
since the fixture need not be inclined at a certain angle, but is
placed vertically onto the bracket. During installation, the shielding
and thus the useful beam must be aligned such that they point
exactly towards the detector.

The radiation warning sign identi-
fies the start of the controlled area,
provided the controlled area is
out-
side the shielding. If the controlled
area is inside the shielding, then
the radiation warning sign
attached on the shielding suffices.
