The controlled area
A controlled area becomes necessary when
the level of radiation exposure from the
handled radioactive material reaches such
high values that it becomes a require ment
by law. For the maintenance of controlled
areas and for the safety of the employees
working there, certain facilities are necessary,
for example, a controlled air ventilation
system for the building, an exhaust air
system, changing rooms, an access control
system as well as systems that measure the
amount of radiation exposure of employees.
Inside controlled areas, strict rules of conduct
have to be kept, for example, no smoking
or eating is allowed.
