Radiometer of radon daughters "ATLESH-1M"
|
Radiometer "ATLESH-1M" is designed for express measurements of equivalent equilibrium volumetric activity (EEVA) of radon in air of dwelling and working premises.
Radiometer can be used for:
- Integrated sanitary-hygienic survey of dwelling and non-dwelling premises of radon hospitals and underground structures ( storage facilities, tunnels).
- Radiation control of construction objects
Radiometer "ATLESH-1M" applies express method of measurement of equivalent equilibrium volumetric activity of radon by means of pumping high volume of air through analytical filter. Such method increases sensitivity of instrument, shortens measurement time and ensures reliability of obtained results.

200...250 litres |
Time of air pumping and measurement of equivalent equilibrium volumetric activity |
8 minutes |
Radiometer saves its characteristics in range of ambient temperature |
From 0 up to 40 °C |
New radiometer "ATLESH-1M" is designed on the basis of current achievements of microchip technology. All operations are automated and very convenient. In process of measurements the operator receives prompts, as well as quick and easy-to- understand result, for example: EEVA = 45 Bq/m3 ±10%.
Microprogram of instrument performs the following functions: background measurement, electromagnet fixation of cassette till measurements are over, measurement of consumption of pumped air, calculation of result and statistical error, displaying data and prompts.
