Abstract

U ovom radu ispitana je prisutnost odnosno koncentracija radona i torona kao rezultat ekshalacije iz građevinskih materijala. Brojni građevinski materijali sadrže elemente u tragovima čijim radioaktivnim raspadom nastaju nove nestabilne jezgre tzv. kćerke. Krajnji produkt raspada radona su teški metali te energija ionizacije koji predstavljaju opasnost za živu tvar. Mjerenja su izvođena u laboratoriju za spektroskopiju na RGN fakultetu na 5 uzoraka različitih građevinskih materijala. Izmjerene vrijednosti ravnotežne koncentracije za uzorke granita i cementa nekoliko su puta veće od prosječne procijenjene vrijednosti koncentracije za građevinski materijal. Usporedba rezultata dobivenih tijekom ovog ispitivanja s rezultatima iz objedinjene baze mjerenja ekshalacije radona iz građevinskog materijala ukazuje na velike razlike u dobivenim vrijednostima. Prisutnost i povišene vrijednosti koncentracije radona u uzorcima građevinskog materijala izmjerene prilikom ovog ispitivanja potvrđuju potrebu za praćenjem vrijednosti radona u građevinskom materijalu iskazanu u drugim znanstvenim radovima na istu temu.

Abstract (english)

In this thesis, the presence and the concentration of radon and thoron as a result of exhalation from building materials was examined. Numerous building materials contain trace elements whose radioactive decay creates new unstable nuclei, the so-called daughters. The final products of radon decay are heavy metals and ionization energy, which pose a danger to living beings. The measurements were performed at the RGN Faculty in the spectroscopy laboratory on 5 samples of different building materials. The measured equilibrium concentration values for the granite and cement samples are several times higher than the average estimated concentration value for the construction material. A comparison of the results obtained during this test with the results from the unified database of measurements of radon exhalation from building materials indicates large differences in the obtained values. The presence and elevated values of radon concentration in construction material samples measured during this test confirm the need to monitor the radon value in construction material stated in other scientific works on the same topic.
