Merenje ekshalacije radona iz građevinskih materijala

Abstract

Prikazan je pregled najnovijeg gama metoda za merenje ekshalacije radona iz građevinskih materijala, koji pored ekshalacije omogućava merenje faktora emanacije i merenje difuzione dužine radona u datom materijalu, što nije moguće u standardnim merenjima ekshalacije radona. Takođe su prikazana i još tri standardna metoda merenja ekshalacije radona i dato je uporedno objašnjene prednosti i mana ovih metoda. Biće dat i pregled dosadašnjih merenja u Srbiji.

A review of a new radon exhalation measurement method is presented. This method provides also a measurement of the radon diffusion length and the radon emanation coefficient, which is not possible by standard radon exhalation measurement methods. Besides, three standard radon exhalation measurements are presented: closed chamber with an active instrument, closed chamber with a solid state nuclear track detector and a charcoal canister method. An intercomparison of advantages and disadvantages is also given. A short review of previous measurements of radon exhalation from comercial building materials in Serbia will be given in the presentation.
