Helgeson 'Quicky' In-Vivo Counter is a whole-body counter. The 'Quicky' is used to rapidly screen personnel or it can be used with a fixed counting time to obtain more precise results. The printed results provide the documentation for subject identification, counting time and date.

Results can be reported with different units of measurements. The 'Quicky' can reduce your regular counting requirements and costs significantly.


'Quicky' has a 'user-friendly' software with a menu format that provides a variety of standard and optional operating programs. System performance software includes a Quality Assurance program that checks the electronics of both the NaI(TI) and proportional counters, reporting any malfunctioning to the operator. An Energy Calibration program allows the gains of the individual detector-amplifier systems to be adjusted to uniformity and conformity to the design parameters.

The 'Quicky' is a high-performance instrument that uses four NaI(TI) detectors and/or twenty gas flow proportional counters (according to the customer requirements). This instrument will perform quantitative measurements of internally deposited radionuclides as well as determining the amount and location of external contamination. A linear geometry minimizes counting errors due to weight and height differences.

The 'Quicky' system features a continuous background monitoring capability which reduces counting time and increases accuracy. Electronic components are chosen for long term unattended operation and stability.
