“…The mean value of potential alpha energy concentration of short-lived radon daughters was 0.12 μJ•m −3 , maximum value -6.89 μJ•m −3 . In addition, they showed an increase of other indicators [20]. Similar studies were performed in British coal mines [21].…”

This paper discusses the problem of assessing the negative after-effects of low doses of ionising radiation exposure in humans. Radon and its decay daughter products are the most widespread source of such irradiation. Miners (in both uranium and non-uranium mines) as well as laypeople in domestic life may be exposed to radon, making the problem of assessing the cytogenetic effects of exposure extremely crucial. One of the more promising test systems to assess the effect of radon is the cytokinesis-block micronucleus assay (CBMN) on peripheral blood lymphocytes, which has a number of advantages over other cytogenetic techniques. Recent progress and future prospects of this cytogenetic method are discussed here.

“…The results of the assessment conducted in 1995 showed that the approximate amount of 226 Ra in water flowing into the USCB coal mines reached 625 MBq/day (230 GBq per year), while that of the 228 Ra was ≈ 700 MBq/day (255 GBq per year). Although radium concentrations in sulphate-rich waters were usually less than in barium-rich waters, the total activity of radium in inflows to mines with sulphate-rich radium-bearing waters was much greater (Skowronek et al 1998;Wysocka et al 2017). It should be pointed out that significant concentrations of radium isotopes in waters can only be found in active mines; in closed mines, the mixing of inflows from different aquifers causes the concentration of radium isotopes to not exceed 0,5 Bq/L.…”

“…-Several coal mines in which barium-rich waters with elevated concentrations of 226 Ra were closed; -An increase in the inflows of water with higher concentrations of 228 Ra than of 226 Ra (by a factor of approximately 2) was observed in the three coal mines that are the most important contributors to the daily release of 228 Ra; -Deepening of the exploitation level allowed access to new coal seams where formation waters with elevated radium concentrations occur. The best example is that the radium level in one of the collieries prior to 2010 did not exceed 0.2 Bq/L, but as a result of exploitation at the deeper horizon, the radium activity in inflowing waters increased to 5-7 Bq/L, while the radium content in the discharge waters was 1.5-2.5 Bq/L (Skowronek et al 1998;Wysocka et al 2017). -A reduction in radium removal from underground installation water due to technical and economic problems.…”

Natural Radioactivity in Polish Coal Mines: An Attempt to Assess the Trend of Radium Release into the Environment

et al. 2019

The highly mineralised formation waters in the coal mines of Poland's Upper Silesian Coal Basin contain natural radioactive nuclides, mostly radium. The 226 Ra concentration in the groundwater that flows into the underground mine workings reaches 390 Bq/L, and is sometimes exceeded by the 228 Ra concentration. The radium-bearing water sometimes also contain barium ions, which enables coprecipitation of barium-radium sulphate. Another type of radium-bearing water contains sulphate ions instead of barium; in this case, radium is transported to settling ponds and downstream. We have assessed the daily activity of radium in waters flowing into the underground mines and being discharged to the environment. Based on 1995 data, we estimate that the total activity of radium isotopes flowing into the mines was about 1300 MBq/day, while the radium activity in the discharge waters was about 700 MBq/day. A similar assessment performed with 2016 data indicated that the total activity in inflows was roughly 1150 MBq/day, while that discharged to surface waters was about 450 MBq/day.

“…According to the ICRP report [ 10 ], the equilibrium factors for a reference worker (average breathing rate of 1.2 m 3 /h) are equal to 0.4 in indoor workplaces, 0.2 in mines, and 0.4 in tourist caves. As has been shown in different studies, the equilibrium factors can differ considerably from the values mentioned above [ 12 , 13 , 14 ], especially when mechanical ventilation is applied. According to a comprehensive study carried out by Chen and Harley [ 12 ], the equilibrium factors varied from 0.08 to 0.72 for active mines in 18 countries and from 0.10 to 0.85 for caves, tourist mines, and thermal spas.…”

The article presents a model for simulating changes in the activity concentration of radon and thoron as well as their progeny in closed or poorly ventilated systems. A system can be considered closed when a stream of radon and thoron flows into a space, but nothing comes out. It was also assumed that there may be devices or installations with a filtering system that would reduce the concentration of radon and thoron decay products. These assumptions may, therefore, correspond to a situation in which, in an isolated chamber, the calibration of radon hazard-monitoring devices is carried out, and nuclides are supplied from an emanation or flow through sources or well-isolated spaces in an environment where the source of nuclides is, for example, radon and thoron exhalation. The differential equations were formulated on the basis of the assumption that the activity concentration of radionuclides of concern in the space is uniform. The equations do not consider possible losses due to diffusion or the inertial or gravitational deposition of aerosols. If these phenomena have a limited impact on changes in the activity concentration of nuclides, the solutions provided may be used to simulate the activity concentration of radon and thoron and their decay products in any confined space assuming different boundary conditions.
