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.

Measurement range of  EEVA of adon in airFrom 10 up to 9999 Bq/m3
The limit of permissible major relative error±30%

Power supply is performed from the main of alternative current with voltage from187 up to 242 V and frequency 50 ± 1 Hz or from the built-in rechargeable battery
Overall dimensions, mmNot more than 380x200x170
Mass, kgNot more than 8
Air volume pumped through filter200...250 litres
Time of air pumping and measurement of equivalent equilibrium volumetric activity8 minutes
Radiometer saves its characteristics in range of ambient temperatureFrom 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 скачать dle 12.0
