PAEC Integral Monitor - Radonis 1.0
From personal dosimetry to environmental control in one device.
Integral Monitor KLE – Radonis 1.0 enables precise measurement of the time-integrated potential alpha energy concentration. With two adjustable air flow rates, it easily adapts to different measurement conditions. Unlike conventional dosimeters, Radonis 1.0 is equipped with a built-in timer that allows monitoring of its usage duration.
- It supports two independent air pump modes for maximum operational flexibility.
- The device is approved by the Czech Metrology Institute as both a personal dosimeter and a workplace environment monitor.
- Operation is ensured either by a rechargeable battery or by mains power for continuous use.
- It is designed for universal application in environments with varying concentrations of radon progeny.
- An optical control system optimizes pump performance and ensures stable operation.
Specification of Use: Personal dosimeter or integral monitor of potential alpha energy concentration (PAEC) / equilibrium equivalent activity concentration (EEAC).
Measured Quantity: Time integral of the potential alpha energy concentration / equilibrium equivalent activity concentration.
Intended Environment of Use: Atmosphere in mining, underground, occupied, and residential spaces.
Sampling Method: Air sampling through a filter.
Detection Method: Optical summation of chemically etched tracks created by the interaction of alpha particles with the sensitive layer of the track detector.
Calculation Method: Based on the linear relationship between the time integral of PAEC / EEAC and the track density on the detector.
Dosimeter Wearing Options: The dosimeter can be worn either on a belt or on a shoulder strap.
PAEC Integral Monitor is designed as a combination of the personal dosimeter body (A) and the sampling head (B). The construction allows easy access to the individual functional parts of the device.
In the sampling head, the components are protected by a cover (C), which can be removed by loosening the fastening screws. Once the cover is released, the track detector (D) becomes accessible. It is positioned above the braking foil (E), which protects the sensitive layer of the detector towards the aerosol filter (G). Stable placement of all elements inside the head is ensured by the collimator (F), which also defines the precise position of each component.
If required, the aerosol filter type AFxxx can be replaced with a Dαxxx filter, which is designed for the determination of the activity concentration of long-lived alpha-emitting radionuclides.
