Epidemiological Cohort

The comparison of complex epidemiological (cohort, case-control and ecological) studies of Radon influence on incidence of lung cancer among mining populations of world mines and residents of the city of Rivne was conducted. The calculation of additional relative risk for the residents of the city of Rivne by the method of epidemiological ecological studies performed on radiometric equipment AlfaRad+and calculated according to the BEIR VI risk model in two variants: exposure-age-duration (EAD) and exposure -age-concentration (EAC) was conducted. The values of the risk coefficients of the dependencies of the relative risk on Radon exposure we obtained for residents of Rivne are lower than the ones obtained for miners (according to literature) – 0.31 (EAD) and 0.49 (EAC) per 100 WLM for volumetric activity (VA) of Radon in housing 200 Bq/m3 and 1420 Bq/m3. The thesis about the impossibility of automatically applying the obtained dependencies of additional relative risk of lung cancer on exposure to Radon for miners to the general population according to the variants of risk models proposed in BEIR VI was verified.

Radon Isotopes

Abstract Measurements of the spatial distribution of radon isotopes were carried out from April 2021 to August 2021 in the foothills of the Trans-Ili Alatau of the Tien Shan in the Almaty region at various heights above sea level: from 500 to 2500 meters. They were carried out using electronic radiometric equipment: beta-dosimeter “RKS-01B-SOLO”; gamma dosimeter “RKS-01G-SOLO”; radiometer of radon and its daughter decay products “RAMON- 02” in the field. As a result, preliminary assessment schemes were built for route measurements of the 222Rn radon isotope, beta and gamma radiation fields from natural daughter products of decay of radon isotopes and radionuclides located in the surface atmospheric layer.

Parallel Measurements

Recent results obtained from a pilot plant study showed that the rate of morning temperature increase in surface water is significantly correlated with the degree of water pollution expressed as turbidity. The aim of the present study was to validate the above findings under field conditions. Two oxidation ponds differing in their effluent quality were investigated during the summer. In clear weather and moderate winds the ponds were thermally stratified. Continuous records of subsurface temperature and parallel measurements of turbidity provided data for statistical analysis. The variables tested appeared significantly correlated and the more polluted pond exhibited consistently a higher rate of morning temperature increase. Temperature measurements can be carried out remotely using airborn IR radiometric equipment. The thermal method should be applied together with visible spectrum imaging, which can identify pollution components according to the specific waveband of the reflected light.
