ALPHARAD PLUS

Measurement system for monitoring of radon, thoron and their airborne progenies

Measuring system (radiometer) to monitor the activity of Radon, Thoron and their progenies in open air, occupational air, water, soil air (soil atmosphere) and airflow from ground formation.

Application

Radiation Instrumentation Laboratories

Public security

О Комплексе

Area of application:

Mining industry (especially uranium mines)
Earthworks, ground excavations and openings
Construction works
Occupational air monitoring
Fresh water and drinking water monitoring
Sanitary survey of living and working areas

Measuring capabilities:

Equivalent equilibrium volumetric activity of Radon in air
Equivalent equilibrium volumetric activity of Thoron in air
Volumetric activity of Radon (222Rn) in air
Volumetric activity of Radon (222Rn) in water samples
Volumetric activity of Radon (222Rn) in samples of soil atmosphere
Flux density of Radon in airflow from ground formation

The monitor is suitable for work inside stationary and mobile radiological laboratories as well as in the field (at certain conditions).
