RESUMO
We present here a brief review of the lines of research presented at the section Ecology and Human Health of the XIVth Conference on Physics and Radio Electronics in Medicine and Ecology (PhREME'2020), July 1-3, 2020, held in Vladimir City.
RESUMO
Quantitative assay of nitric oxide (NO) and iron (Fe) was carried out by the electron paramagnetic resonance (EPR) method in epidermal derivative (hair) of 45 liquidators of the Chernobyl accident, 30 employees of radiological institutions having contact with radiation, and 50 students of Vladimir State University, most of which were diagnosed with iron deficiency, namely iron deficiency anemia (4 persons) and latent iron deficiency (34 persons). Measurements were performed on a Radiopan EPR-spectrometer. It was found that the method of quantitative EPR-spectroscopy using diethyldithiocarbamate as a trap in vitro could be successfully used to measure NO-radical activity in such a biological substrate as hair. It was found that the intensity of NO-radical signal in the spectrogram depends on the Fe level (not only in the analyzed substrate, but also in the whole organism).

Hardware, circuitry, and software suggested in this work make it possible to use the SLS-9 X-ray simulator for classical and computer tomographic imaging. The suggested hardware and software can be used as a basis for designing special-purpose tomographic systems.
