Thyroid measurement version of BSI Whole Body Counting system (WBC) is made of light and compact aluminum construction which is really easy to handle for everyday usage. The main holder has wheel base and handle to move the measuring part around the facility. When it is fixed in certain location, the operator is capable of adjusting the position of the detector in vertical and horizontal position to find the most convenient position for the person being analyzed.
Different sizes and materials of scintillation detector can be used in accordance to customer’s preference.
In order to guarantee the best performance of the system in terms of MDA, our detector is covered with lead shied and equipped with collimator. Moreover, the comfortable chair has lead plate installed in the back to avoid interference of other objects and to have good parameters of background.
