Phantom of the lungs PLT-02

Purpose and Scope

Phantom PLT-02 is designed for calibration, verification and comparison of whole body spectrometers  of  SEG-01T, SEG-02T, SEG-10P types and other measuring instruments  of activity of incorporated radionuclides in the human body using a scintillator and semiconductor gamma-ray detectors in the energies range from 50 to 3000 keV.

Phantom is used in centers of radiation medicine, public health units, research institutes, testing laboratories and other institutions conducting radiation monitoring of personnel and public.

Description

Phantom PLT-02 is represented by a set of polyethylene blocks and a set of volumetric radionuclide sources which are to be assembled on the manufacturer premises or on-site as the model of lungs phantom, chest phantom with the given radionuclide content.

The volume and the anatomical location of the heart between the lobes of lungs are imitated by the lay of grooves and cutouts in the polyethylene blocks.

The assembled polyethylene blocks with two volumetric radionuclide sources installed in them makes a model of the chest with lungs, adequate by its interaction with gamma radiation to soft biological tissue, bone biological tissue (rib shirt, sternum, spine) and pulmonary biological tissue (PBT). Active imitator of pulmonary tissue complies with the model containing uniformly distributed radionuclide.

Phantom assembly, made with radionuclide sources, makes a reference sample of activity of incorporated radionuclides uniformly distributed in the lungs.

Reference sample functions as the sample and reproduces space-energy spectrum of gamma radiation of incorporated radionuclides for transferring radionuclide activity values to whole body spectrometer by means of its calibration.
