Operating the Instrument
General
The new Thoron-Scout is a versatile, easy to use and state-of-the-art instrument focussed on
the detection of Thoron (Rn-220) and Radon (Rn-222) in the ambient air. The required fast
exchange rate of sampled air is realized by a highly permeable chamber placed outside the
instruments enclosure. The relative Thoron sensitivity is comparable with the one of pump
based instruments.
Beside the activity concentration of Thoron and Radon, air temperature, relative humidity and
barometric pressure will be determined and saved to a non-volatile circular memory (first in –
first out). Up to 2000 chronological data sets will be available for data transfer to PC including
alpha spectrums. An internal real time clock ensures a correct time regime, a tamper lock
indicates dislocation during the measurement. A display with backlight informs about the
actual readings.
Neither mechanical parts like membrane pumps nor an external power supply are required.
Therefore, use and exposition at home or at workplace is possible without any disturbance. A
total duration of measurement of up to four weeks with continuous data recording is possible.
Due to its small dimensions and little weight, the Thoron-Scout can be shipped by mail to the
place of interest/measurement without any additional man-power required for installation or
start-up of an analysis – even untrained staff is able to start a measurement.
Entire part of delivery will be comfortable software for data read out and graph presentation,
dose assessment and easy data backup.
