A whole-body counter in SÚRO (NRPI) Prague, Czech Republic has been upgraded recently with the goal to enhance its capability of a safe, smooth, accurate and reproducible positioning of detectors for whole- and partial-body counting. The counter is intended especially for counting of low energy gamma emitters in various organs and tissues of the human body. Counting efficiency calibration of a four-detector system installed in the shielded room has been performed by means of physical and voxel phantoms. The consistency of in vivo bioassay data of three internal contamination cases long-term monitored in the Institute is shown. •WBC chamber has been upgraded in order to enhance its counting capabilities.•Experimental and Monte Carlo technique were used for detector calibrations.•Consistency of the in vivo bioassay data for former and new WBC got to be preserved.
