Jednym z mitów dotyczących betonu komórkowego jest jego rzekomo wysoka promieniotwórczość. Taka opinia jest spowodowana brakiem wiedzy na ten temat, plotkami, a czasami skutkiem świadomej manipulacji. Dla właściwego przedstawienia promieniotwórczości materiałów i wyrobów budowlanych, w tym wyrobów z betonu komórkowego, przybliżmy skrótowo zagadnienie promieniotwórczości i przeanalizujmy je opierając się na wiarygodnych wynikach badań upoważnionych jednostek badawczych.

Aerated concrete has been alleged to be highly radioactive. However, these claims can be attributed to ignorance, unconfirmed rumours, or even intentional manipulation. This paper addresses the question of radioactivity of building materials and construction products, including aerated concrete products, based on reliable outcomes of studies conducted by accredited research centres. The radioactivity of buildings made of aerated concrete has been examined in in-situ studies, under the review of structural solutions made of building materials, and in consideration of the requirements and assessment criteria for radioactivity hazard of construction products and buildings.

Measurements of the short-lived radon progeny particle size distributions were performed under realistic natural conditions in 54 dwellings in 6 regions of Poland by means of the Radon Progeny Particle Size Spectrometer (RPPSS). The RPPSS comprises a one open face stage, a 4-stage diffusion battery and a 3-stage multi-hole inertial impactor. It was manufactured at the ARPaNSA (Melbourne, Australia), under supervision of Dr S. B. Solomon and supplied with his software. While using the continuous mode, the programme provides analysis of the potential alpha energy concentration on each stage, particle size distributions and weighted dose conversion factors based on the ICRP human respiratory tract model (HRTM) as implemented in the computer code RADEP (radon dose evaluation program). The unattached fraction indoors ranges from ca. 0 to 53% with an arithmetic mean and median of 17%. The equilibrium factor F was observed in the range from 7 to 64% with an arithmetic mean of 32% and median of 29%. The annual effective doses from radon progeny for the general population were estimated according to two models: epidemiological and dosimetric. The mean values of the ratios of the dosimetric to epidemiological dose estimates for the general population (breathing rate 0.78 m3/h) and workers (breathing rate 1.2 m3/h) are 1.0 and 1.4, respectively. The epidemiological dose estimates for the general population are smaller in comparison with the dosimetric estimates for the unattached fraction fp greater than 17%. It was shown that the dependence of the ratio of the doses estimated on the basis of two models on the unattached fraction fp is well described by a linear equation.

Six radon laboratories, which perform indoor radon measurements to jointly investigate temporal variations of radon concentration in houses in a couple of regions in Poland, participated in the intercomparison exercise. There are involved three commercially available Hungarian RadoSys systems and four own laboratory methods. All of them are based on the etched-track CR-39 detectors. The intercomparison was conducted in a calibration laboratory of the Central Laboratory for Radiological Protection (CLOR), Warsaw, Poland, accredited by the Polish Center for Accreditation (previously AP 101, at present AP 057). Comparison measurements were performed during three expositions in the CLOR’s radon calibration chamber under controlled normal climatic conditions and steady radon concentration. The results were referred to the value of the radon concentration determined by AlphaGUARD monitor traceable to the primary 222Rn standard in Physikalisch-Technische Bundesanstalt (PTB), Braunchweig, Germany. The mean performance ratio defined as a ratio of the reference to participant’s result range from 0.88 to 1.31.

In a region of two lithologic units: the Augustów Plane sandr and the Suwałki sands and fluvioglacial gravels, 134 measurements of radon concentrations in dwelling houses were performed. An integral method of solid state nuclear trace detectors (SSNTD) was used in the studies. Statistically significant differences in the radon concentrations in both geological units were obtained. The radon concentration arithmetic mean was 197 Bq m-3, geometric mean - 119 Bq m-3, median - 111 Bq m-3, the maximal value being 1225 Bq m-3 in the region of the Suwałki fluvioglacial sands and gravels. The Augustów Plane sandr revealed arithmetic mean of radon concentration equal to 123 Bq m-3, geometric mean – 80 Bq m-3, and median equal to 67 Bq m-3, maximal value 695 Bq m-3. The annual effective dose of the radon obtained by inhabitants of the Augustów Plane sandr is 1.7 mSv and for inhabitants of the Suwałki fluvioglacial sands and gravels it is 2.5 mSv.

Przeprowadzono pomiary stężenia radonu wewnątrz budynków mieszkalnych zbudowanych na dwóch typach podłoża: piaszczysto-żwirowym i gliniastym. Pomiary przeprowadzono całkującymi detektorami śladowymi, użyto folii CR-39. Przeprowadzono również w obrębie obu wydzieleń litologicznych pomiary stężenia radonu w powietrzu glebowym. Średnia arytmetyczna stężenia radonu w powietrzu piwnic na podłożu piaszczysto-żwirowym wynosiła 276 Bq m-3, a na podłożu gliniastym 587 Bq m-3. Średnia arytmetyczna stężenia radonu w powietrzu glebowym podłoża piaszczysto-żwirowego wynosi 39,77 kBq m-3 a podłoża gliniastego 26,66 kBq m-3. Stężenie radonu w wodzie studziennej (8367 Bq m-3) było wyższe na całym badanym terenie w porównaniu ze stężeniem w wodzie wodociągowej (2690 Bq m-3).

Measurements of radon concentrations in indoor air were carried out in dwellings built on two types of soil, i.e. sandy -gravel soils and clay soils. An integrative method of a-track film was used. The radon measurements in soil air were performed for both types of soils. The arithmetic mean of radon concentration in cellar air within gravel-sandy soil was 276 Bq m^-3, whereas within clay soil - 587 Bq m^-3. In turn, these value in soil air in sandy-gravel area reached 39.77 kBq m^-3, whereas in clay soil - 26.66 Bq m^-3 The concentration of radon in the household well water in the whole examined area was higher (8367 Bq m^-3) compared to that " water from supply system (2690 Bq m^-3).
