Universal whole body phantom 
Reference materials


The Universal Whole Body Phantom (UWBP) is used for calibration of a whole body counters (WBC) for measuring the activity of radionuclides incorporated in human body with use of scintillation, HPGe or other type of detectors of gamma-radiation in the energies range from 50 to 3000 keV.
The Phantom can be used in radiation medicine centers, nuclear power stations, research institutes, industrial hospitals and other institutions performing radiation monitoring of personnel and population, as well as by the Federal Agency for Technical regulation and metrology in order to comply with the Traceability Law.

It is an alternative to the BOMAB phantom, eliminating the risk of leakage of radioactive solutions.


Universal whole body phantom is based on reference radionuclide sources and it adequates on interaction with gamma-radiation to biological soft tissue of the human body, containing uniformly distributed radionuclide.
Universal phantom is a collapsible construction and includes a set of components:
  - Polyethylene blocks of a type "full" (90pcs.) and "half" (40pcs.);
  - Rod reference radionuclide sources of a type "nominal" (180pcs.) and "half" (80pcs.);
  - Connectors (280pcs.);
  - Fixings (10pcs.);
  - Tripod (stand);
  - Mounting blade;
  - Pusher;
  - Pen-box;
There are six types of the whole body phantom assembly with age and anthropometric characteristics given in table, for the three standard measurements geometries on whole body spectrometer: standing (lying), sitting and sitting bended.

The whole phantom with radionuclide sources forms a reference sample of activity of incorporated radionuclides uniformly distributed in the human body. This reference sample reproduces the gamma-radiation spatial-energy spectrum of incorporated radionuclides to transfer the activity value of radionuclides to whole body spectrometers by means of its calibration.
Rod sources are made in the form of the sealed radioactive sources, which eliminates the intake of radionuclides into the environment by transportation, storage and use. Assembly of polyethylene blocks without the radionuclide sources forms the background samples (background phantoms) of the appropriate size.

Standard values of activity
  Am-241          10 kBq
  Ba-133           10 kBq
  Cs-137           10 kBq
  Co-60            100 kBq
  Eu-152           1000 kBq

The whole body phantoms can be provided for rent.

This phantom can be calculated using the MCC-MT software.
