THE MAYAK WORKER DOSIMETRY SYSTEM-2013 (MWDS-2013): PHASE II-QUALITY ASSURANCE OF ORGAN DOSE CALCULATIONS.

abstract：:New imaging technologies utilising X rays and radiopharmaceuticals are continuously under development. The benefit of computed tomography (CT) has been so dramatic that there is a tendency to overuse it and not to place enough efforts into optimisation of the technique. It is also now more and more common to combine t...

The relative values of such errors depend principally on the measurement methods used, the radon concentration to be measured and the duration of the measurements. Typical exposure times for radon surveys using passive detectors [nuclear tra...
