2.2 Ambient conditions during operation and storage
The shield was specifically designed for use in rough ambient conditions. The
compliance with the operating conditions specified below contributes to
guaranteeing the permanent functionality of the shield and the prevention of
damage.
Shields containing radioactive substances and sources are to be stored in a
lockable storage room complying with the national requirements as regards the
storage of radioactive substances.
Furthermore, the following prescribed ambient conditions are to be observed:
•
The minimum admissible operating/storage temperature is -40°C. Below this
temperature, the sealing rings of the shield may become brittle. In such case,
the leakproofness of the shield can no longer be guaranteed.
•
The maximum admissible operating/storage temperature is +100°C. Above this
temperature, the sealing rings of the shield may be destroyed. In such case,
the leakproofness of the shield can no longer be guaranteed.
•
The higher the dust and dirt content of the environment, the more likely
stiffness or an entire blockage of the locking mechanism is. For this reason, the
functional test intervals (see chapter 6) should be adjusted to the ambient
conditions.
•
Highly combustible or explosive substances must not be kept in the vicinity of
shields in order to prevent a fire from spreading to the radioactive substances.
