Solid Track Etching System For Radon Cumulative Dose Monitoring Neutron Dose Measurement

STE46 Solid Track Etching System 

Product Introduction

STE46 Solid Track Etching System is a precision measuring instrument developed by SHUOBODA, which can accurately measure the cumulative dose of radon in the environment. It is suitable for environmental protection, colleges and universities, nuclear power, research institutions and other fields.

Functional characteristics

When the alpha particles emitted by radon decay bombard the detector, it produces submicroscopic damage tracks. The detector is chemically etched under certain conditions to expand the damage track so that it can be read and counted with a microscope or counting device. The number of tracks per unit area is proportional to the product of radon concentration and exposure time. The scale factor can be used to convert track density into radon concentration. Track etching method is passive sampling, and the detector is CR-39, which is placed in a sampling box of a certain shape to form a sampler. The new developed electrostatic collection type sampler has a detection limit of up to 0.6Bq/m3.

System Features

Multi-Focal Plane Image Recognition Technology

Solid track detectors may accumulate dust and non-detectable damage during daily use and during the etching process. These can interfere with normal measurements and make it difficult to distinguish between valid tracks and impurity interference. Multi-Focal Plane Image Recognition Technology uses different focusing distances to create different focal plane images of the object being identified to distinguish valid tracks from impurity interference.

Intelligent Recognition Mode

This system combines machine learning algorithms with manual intervention to significantly improve track recognition and counting performance.

Other Features

The STES solid track etching system can perform secondary analysis and statistics on up to 32,000 field-of-view images.

Reading results can be exported in .csv file format and Excel spreadsheets.

Equipped with track image reanalysis software for advanced users: batch image analysis and detailed track morphology information.

Detection Limit:

Using a standard passive radon detector: 5 Bq/m³;

Using an electrostatic accumulation radon detector: 0.6 Bq/m³.

Efficient Etching System

The etching system can etch from one to 256 detectors at a time, depending on the user's workload. Etching small batches of detectors can reduce etchant usage and hazardous waste. The etching system's internals are constructed of corrosion-resistant materials, enhancing the safety and reliability of the etching process.

Detector Compatibility

Can read CR-39 detector elements of any shape. It can read 64 square CR39s (1cm x 1cm);

It can read 16 round CR39s (2.4cm diameter);

It can read custom CR39 shapes and sizes up to 12cm x 12cm (with customizable reading field position and order).

Technical Parameters:

Standard Configuration

The radon cup is designed through air exchange rate, cup shape and material to ensure that radon can diffuse into the radon cup with target effect within a given sampling period.

Radon accumulation measurement requires the detector (CR-39) to be placed in the radon cup to form the entire sampling system. The detector that completes sampling under certain conditions is etched under certain conditions, then through the solid track reading system, it can accurately measure the radon cumulative dose in the environment.
