title: Rapid assessment methodology in NORM measurements from building materials of Uzbekistan.
abstract: Utilizing low cost NaI(Tl) scintillation detector systems we present methodology for the rapid screening of building material samples and the determination of their Radium Equivalent Activity (Raeq). Materials from Uzbekistan as a representative developing country have been measured and a correction coefficient for Radium activity is deduced. The use of the correction coefficient offers the possibility to decrease analysis times thus enabling the express measurement of a large quantity of samples. The reduction in time, cost and the use of inexpensive equipment can democratize the practice of screening NORM in building materials in the international community.
