[en] The unmanned airborne vehicle (UAV) platform, equipped with an appropriate payload and capable of carrying a variety of modular sensors, is an effective tool for real-time control of environmental disasters of different types (e.g. nuclear or chemical accidents). The suggested payloads consist of a miniaturised self-collimating nuclear spectrometry sensor and electro-optical sensors for day and night imagery. The system provides means of both real-time field data acquisition in an endangered environment and on-line hazard assessment computation from the down link raw data. All the processing, including flight planning using an expert system, is performed by a dedicated microcomputer located in a Mobile Ground Control Station (MGCS) situated outside the hazardous area. The UAV equipment is part of a system designed especially for the critically important early phase of emergency response. Decisions by the Emergency Response Manager (ERM) are also based on the ability to estimate the potential dose to individuals and the mitigation of dose when protection measures are implemented.

[en] Using infrared spectroscopy, we studied the character of intermolecular interactions in the samples blood plasma of oncological patients with bone metastases in the treatment of their modern β-emitter ¹⁵³Sm-oxabifor. The therapeutic dose of the ¹⁵³Sm-oxabifor was 1.0 mCi/kg of the patient's body weight. Analysis of the IR-spectra showed that already after the first course of palliative radionuclide therapy there is a tendency to balance the products of free radical nature and antioxidants, which indicates the effectiveness of the treatment. Molecular changes in the blood plasma of cancer patients with bone metastases registered using infrared spectroscopy are specific during palliative therapy. (author)
