Abstract
Natural radioactivity, radon exhalation and rock properties have been studied using gamma spectrometry, CR-39 detectors
and weighing methods. Statistical tool was used to study the relationship between the activity concentration and properties
associated with the rocks. The purpose is to determine the rocks with good properties and lower radioactivity levels in order
to reduce radiological efect when used as building materials. Gneiss recorded good properties while quartzite was found
to contain poor and lower value of radiological parameters as compared to granite and sandstone. Radon-222 was found to
correlate well with the properties than radionuclides of radium-226, thorium-232 and potassium-40.
