For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.
Solutions containing organic solvents, such as low-molecular-mass alcohols, esters, or ketones, enhance absorbances by increasing...

Area of Science:

Metrology
Environmental Science
Nuclear Physics

Background:

Accurate measurement of low-level radon activity is crucial for environmental monitoring and radiation protection.
Existing equipment may lack the precision and stability required for calibrating sensitive radon detectors.

Purpose of the Study:

To develop and characterize unique equipment for testing radon measuring devices at low activity concentrations.
To establish a stable and precisely controlled radon environment for calibration purposes.

Main Methods:

Development of an airtight low-level radon chamber (LLRCH) with a 324 L volume.
Utilized a Rn-222 flow-through source and a radon-free air supply.
Incorporated a mass flow controller and a regulated fan for precise airflow and atmosphere homogeneity.
Integrated climatic condition sensors (temperature, pressure, humidity).

Main Results:

The developed equipment allows for time-stable radon activity concentrations to be maintained for several days.
Radon concentration is precisely controllable within the range of 100-300 Bq·m⁻³.
Ensured homogeneity of the radon atmosphere within the chamber.

Conclusions:

The novel equipment provides a reliable and accurate method for testing and calibrating low-level radon measuring devices.
This advancement supports improved environmental radon monitoring and radiation protection standards.
The system's stability and control capabilities are vital for metrology research in radon.
