Opis:: A review of some experimental results obtained using the dense plasma focus (DPF) device PF-1000 is presented. The copper Ka1,2 radiation line generated by DPF in the case of device anode made of copper was the main object of this study. The predominance of this characteristic radiation over other kinds of radiation in the DPF X-ray spectrum is shown. A brief description of a new DPF 6.0 device as well as a radioenzymology experiment carried out within this device is presented.

Tytuł:: Does occupational exposure to low ionizing radiation affect endothelium health?

low-dose ionizing radiation
Opis:: The aim of this study was to assess the effect of low-radiation exposure on detachment of the vascular endothelial cells. Circulating endothelial cells (CEC) were measured in the peripheral blood by an immunomagnetic separation (IMS) technique in 63 workers occupationally exposed to low-level ionizing radiation at the Atomic Energy Commission of Syria and in 28 controls. We found a significant difference in CEC numbers in the peripheral blood of the workers exposed to low-level ionizing radiation in comparison with those of the control samples (p = 0.0001) and no significant difference in the proportion of other blood elements in the peripheral circulation. Elevated number of CEC in occupational workers exposed to low doses of ionizing radiation may reflect an early affection of the endothelium. Long-term follow-up of these workers must be conducted to determine the clinical value of CEC as an early indicator of cardiovascular disease induced as a result of chronic occupational exposure to low doses of ionizing radiation.

Opis:: The term �gradon event�h indicates here a sudden appearance of enhanced radon concentrations, observed like well expressed peaks in time series of radon concentrations. The peaks are superimposed on normal diurnal periodical curves. The characteristics of radon events are high peak values, a rather short duration and a low radon equilibrium factor. Since radon events appear only in the environment near significant radon emission sources, they were investigated in more detail in the case of the former .irovski Vrh uranium mine (Slovenia), using the existing network of continuous radon progeny measuring devices. Eight different types of radon events were identified in the vicinity of the U-mine disposal sites, lasting for some hours and with the range of their peak levels of equilibrium equivalent concentrations (EEC) of radon from a few Bq�Em.3 to over 200 Bq�Em.3. Exposures to radon events in units of Bq�Eh�Em.3 were estimated for adult individuals of the reference group. They resulted in relatively high effective doses of the range 1.5 �ĘSv per a single event, thus exceeding, e.g. the total effective dose for the public due to radioactive discharges from most nuclear facilities during the whole year.

radon concentration
Opis:: The major part of the radiation dose that humans receive from natural radioactive sources is due to inhalation of radon and its decay products. The study focuses on radon concentration (CRn) investigation in kindergartens and nurseries in the district of Montana. The infl uence of building characteristics on CRn was evaluated. The measurement of the CRn was performed using passive detectors. The survey was carried out between December 2019 and May 2020 with a total number of 602 detectors. The average value of CRn in the premises of the studied kindergartens and nurseries in this district is 125 Bq·m−3 , and the geometric mean (GM) value is 88 Bq·m−3 . The buildings that have built ventilation and sewerage systems have lower CRn. The effective doses of the children and workers were evaluated in order to assess the radon exposure.
