Radon alpha-activity concentrations have been measured inside and outs
ide various building materials by combining a calculational method wit
h the solid state nuclear track detector (SSNTD) technique. Radon eman
ation coefficients of the studied materials have been evaluated. A new
calibration method for determining the radium (Ra-226) and thorium (T
h-232) specific activities of the considered building materials has be
en developed. The radon production rates per unit volume of the studie
d materials have been evaluated. The influence of the material porosit
y on the radon emanation coefficient and radon production rate have be
en investigated.
