The purpose of this work is to develop a portable gamma probe for registration and localization of radiation sources, including for medical use. To achieve this goal, two annual stages have been formed.
The first stage involves the development and manufacture of a detection system "Silicon uncooled scintillator detector", experimental studies to optimize the registration of radiation using the system "silicon uncooled scintillator detector" and the electronic module of the charge-sensitive amplifier. It is planned to make a separate remote module of the signal shaper with a digital display module and a power supply from the USB port of the computer. The research uses a silicon uncooled detector, electronic modules of the charge-sensitive amplifier and signal shape to be manufactured at the NSC KIPT, and a CsI scintillator made in Ukraine.
The second stage involves the development, manufacture and commissioning of electronic modules of the charge-sensitive amplifier and signal shape with digital display module and power supply for a prototype of an autonomous portable gamma probe for registration and localization of radiopharmaceuticals. When using radiopharmaceuticals 99Ts, or 125I, Cu, the developed device can be used in medical institutions in the search and localization of malignant tumors to increase the effectiveness of treatment of patients.

The object of research is fundamental and applied nuclear physics.
The purpose of this work is to create a portable gamma probe for registration and localization of radiation sources, including for medical use.
As a result of the performance of works under contract No. 22X-04-11/2023 for March-December 2023:
- manufacturing and experimental research of a mock-up sample of an autonomous portable gamma probe for registration and localization of radiation of radiopharmaceuticals, incl. for medical use;
- the design of a portable gamma probe consists of a detecting unit and a main unit, which are connected to each other by a 1.5 m long cable;
- the design of the detecting unit of a portable gamma probe was developed based on a silicon uncooled planar detector developed by the NNC KhFTI and a CsI(Tl) scintillator, as well as a charge-sensitive pre-amplifier;
- designed and manufactured the main unit, which consists of a shaping amplifier, a discriminator, a power supply unit, a processor module and a liquid crystal indicator;
- conducted studies of the characteristics of a portable gamma probe with radiation sources of 57Co, 133Va, which showed a spatial distribution of 5 mm at a level of 0.5 from the maximum (source at a distance of 30 mm) in the energy range of 100-400 keV, which allows the use of a gamma probe for medical purposes .
