Abstract. In this paper the influence of some building materials
which are most commonly built in the monolitisation of the solar house
heat storages is treated from the Eco-quality aspect. The ambiental air
Eco-quality of the solar house directly depends on the building materials
built in the heat storage. The special accent is given to the indoor environment
Eco-quality from the radiation aspect. From this point of the view, the
main influence on the indoor environment air quality has the gas radon
(222Rn).
In the design of the solar houses heat storages the most common building
materials are: concrete, stone, sand and brick. These materials were specially
observed in this paper. The contents of the natural radionuclides and the
total equivalent radioactivity in these materials. The knowledge of contents
of the natural radionuclides and total equivalent radioactivity in these
building materials are not of meritore factors for architect by decision
to choice the "health" materials. According the ICRP and UNSCEAR recommendations,
the Eco-quality of the solar house indoor air is defined.
Key words: Solar house, heat storage, building materials,
Eco-quality, natural radiation, gas radon.
EKO KVALITET TOPLOTNIH DEPOA
U ZAVISNOSTI
OD PRIMENE VRSTE GRAĐEVINSKIH MATERIJALA
U radu se tretira uticaj nekih najčešće ugradivih građevinskih materijala
pri monolitizaciji toplotnih depoa solarnih objekata sa aspekta eko-kvaliteta.
Eko-kvalitet ambijentalnog vazduha kod solarnog objekta direktno zavisi
od materijala koji se ugrađuju u toplotni depo.
Poseban akcenat se daje na eko-kvalitet ambijentalnog vazduha sa radijativnog
aspekta. Na kvakitet ambijentalnog vazduha glavnu ulogu sa tog aspekta
ima gas radon 222Rn.
Pri konstrukciji toplotnih depoa kod solarnih objekata, najčešće korišćeni
građevinski materijali su: beton, kamen, pesak i opeka. Stoga je u ovom
radu posebna pažnja posvećena upravo ovim materijalima. Poznavanje sadržaja
prirodnih radionuklida u ovim građevinskim materijalima, kao i njihova
ukupna ekvivalentna radioaktivnost jedan su od meritornih faktora arhitekti
pri opredelenju kod izbora "zdravih" materijala. U skladu sa preporukama
ICRP i UNSCEAR definisan je eko-kvalitet ambijentalnog vazduha kod solarne
kuće.
Ključne reči: Solarna kuća, toplotni depo, građevinski matrijali,
eko-kvalitet, prirodna radijacija, gas radon.
