Abstract

The paper analyzes the relationship of short-lived progenies of radon
and thoron decay. Concentration of progenies is expressed as equilibrium equivalent concentration
of EETC (equilibrium equivalent concentration of thoron) and EERC
(equilibrium equivalent concentration of radon) abbreviated (EEТC/ EERC). Мeasuring of
radon and thoron progenies was carried out in 25 schools in the territory of the City of
Banja Luka using CR -39 (RADUET) detectors. Detectors were exposed for six months and
were set in the staff room at the height of 30 cm from the ceiling in internal wall. The relationship
is determined (EEТC/ EERC) and comparison carried out of obtained results with
the world standards, and then the correlation coefficient between radon and thoron was
determined.
