8.4. Protective foils of foot detectors
Protective foils for the foot detectors (Fig. 50) can be supplied as optional accessories. The foil serves as an
additional mechanical protection of detectors. Foils are inserted inside the base between the detectors and
the hinged protective grids; each detector has its separate foil.
The use of the protective foil can make it impossible to measure contamination by alpha
emitters and influence contamination measurement by beta radiators. Please consult the
manufacturer for their use. If you are using the protective foil, then adjust the correction
constants in the configuration file.
Two types of protective foils are delivered:
A special, very thin foil in a cardboard frame, which can be used when the measurement of alpha
contamination is required;
Fig. 49 Foil in a cardboard frame measurement for alpha radiation
A foil wound around a reel, which is suitable for the instrument for which the measurement of alpha
contamination is not required. The concept of foil rewinding keeps the contaminated part inside
the roll. The contaminated part of the foil may be rewound by means of a standard switchboard
wrench.
