Abstract
By using a sealed technology, radon levels were determined, annual effective dose, the effective content of radium, radon exhalation rate and uranium concentrations to be the total 30 samples materials used to paint the walls of buildings and homes in Iraq. It was found that the recommended value for all samples for radon concentration is with low potency radium content of 300 Bq / m3 and 370 Bq / kg respectively. In addition, Annual effective dose in all values was found to be less than the permission level (10 mSv / y). The values of exhalation rate relative to samples lower than the permission value (57.600 mBq/m2.h) set by UNSCEAR organization. The strong correlation (R2=1). It turns out that the content effective radium with the surface radon exhalation rate, the mass radon exhalation rate, and the uranium concentration, respectively. In general, the studied of 30 samples materials used to paint the walls of buildings and homes in Iraq be safe to use as construction material.
