Explanation/Annotation:For determination of volume activity of radon and thoron into the air.
Detailed model description:Can be used:
- ñàíèòàðíî - of epidemiologic and ecological services for
control over content of radon and thoron in the air of dwellings and
plants;
- in radon hydropathic and special medical laboratories;
- in building industry in case of âûáîðåñòðîèòåëüíûõ grounds, analysis
ðàäîíîîïàñíîñòè of construction materials and designs;
- at enterprises, leading the underground excavations, production
construction materials, development and processing mineral resources,
mining and refining of oil;
- when equipping the bubbler for registration of radon in liquid mediums
(water, oil);
- In research laboratories
priority:
- high selective sensitivity to radon and thoron, based
for the use in device of low-background semiconductor detector
with good permit and spectrometric path;
- express in case of taking a measurement;
- conducting possibility of precision measurements in
research laboratories, provided
inference spectrometric signal on external pulse analyzer;
- ïðÿìîïîêàçûâàþùèé device with microprocessor using;
- is being completed upon the request of customer by the bubbler, probe for fence
air from almost inaccessible spots, charge device for
batteries.
