Efficient operation of the individual dosimetric monitoring service relies on three equally important components:
experienced stuff      modern equipment      perfected in-house processes

Equipment

The measurements are performed with individual thermoluminescent dosemeters (TLD) of Harshaw system (USA), which, depending on their design, can measure whole body doses (x-ray, gamma and neutron exposure), doses to eye lens and skin. Dosemeter design and dose assessment algorithms (software) allow determination of does with high precision and within the broad range of conditions of exposure (energy of ionizing radiation, angular characteristics of radiation field).

Each sensitive element (detector) of a dosemeter is calibrated individually, allowing thus measurements with unparallel precision (comparing to commonly used in Ukraine TLD system DTU-01). 

Harshaw 8800 TLD system has built-in system of checking key operation parameters and quality control, which rules out errors in course of individual dose measurement. Another serious advantage of Harshaw 8800 system is recording of raw measurement data (glow curves) and possibility of re-evaluation of the results of dose measurement, detection of anomalous results etc. High metrological characteristics of Harshaw TLD system as well as overall quality of the laboratory performance were confirmed many times in course of international intercomparisons organized by IAEA and EURADOS,  as well as within the First National Intercomparison of IDM laboratories of Ukraine (2014).

For every monitoring period and for each monitored worker was use personal label with name and the date of return of the dosemeter for readout. This information will help you to avoid shuffling dosemeters and not to miss the date of dosemeter exchange at the end of respective month or quarter.

We use barcode printer and scanner to automate this process and remove the human factor errors in course of issue/use/readout of dosemeters.

Stuff

Integrated personnel of the dosimetry service combines experience and youthfulness,
is open for innovations and constantly works towards personal growth and self-improvement.
