Measurement of Alpha Emitters Concentration in Imported Cigarettes

Abstract

The aim of this study was to measured the alpha emitters concentration of (15) different kinds of imported cigarettes. The nuclear reaction used U-235(n, f) obtained by the bombardment of U-235 with thermal neutrons from (Am-Be) neutron source with thermal flux of (5×10^3 n. cm^-2. s^-1). The Results obtained showed the values of the Uranium concentration, and varies from (0.041 ppm) in five stares kind to (2.374 ppm) in Macbeth (chocolate) 100΄s kind. All the result obtained are within the limit levels as given by UNSCAR data.
