Caution!
Radioactivity!
The radiation protection directives have to be observed.
Controlled areas outside the shielding have to be identified and
secured if they are accessible.
2.5.3 Monitoring Areas
Monitoring areas are operation areas which do not belong to the
controlled area. In these areas, a person may receive an effective
dose of more than 1 mSv in one calendar year.
The monitoring area starts at the controlled area. It is an area in
which persons staying permanently in this area may be exposed to
a radiation level of more than 1 mSv in one calendar year. For a
stay of 40 hours per week and 50 weeks per year the area is be-
tween the dose rate limit values of 3 µSv/h and 0.5 µSv/h. It has
to be ensured that persons are not exposed to a dose exceeding
1 mSv per year, taking into account the actual time they stay in
this area. This means that no permanent work place may be set up
in this area.
