Intended Use
Farmer chambers types 30010, 30011, 30012,
and 30013 are standard chambers for absolute
and relative dosimetry in combination with preci-
sion electrometers according to IEC 60731.
With their outside dimensions they are compatible
with the Farmer chambers from other manufactur-
ers. The chambers differ in the material used for
the chamber walls and for the central electrode.
Furthermore, the Farmer chamber type 30013 is
waterproof. The chambers are used for measure-
ments in the radiation beam in radiotherapy or for
reference purposes in secondary standard labo-
ratories.

The Farmer chambers types 30010, 30011,
30012, 30013 will be referred to as detectors in
the following chapters. A differentiation between
the Farmer chambers types 30010, 30011, 30012,
and 30013 is only made when necessary due to
technical differences.
