3.2.3 Shieldings for Installation in a Container with
Manually Operated Lock
The shielding consists of a lead-filled
steel pipe, with a guide tube for the ra-
dioactive source installed in the center.
The radiation exit channel is located in
an angle of 90° or 45° relative to the
longitudinal axis.
After taking off the covering cap which is
secured by a lock you may open the
knurled screw and, using the stay bar,
move the radioactive source forward
(OPEN) or back (CLOSED).
