Peri£¿anu %A Ana Neac£¿u %J Analele Universitatii Bucuresti : Chimie %D 2010 %I %X In this paper basic formulas are developed for the calculation of the absorbed dose rate outside of a gamma radiation source of an empty cylinder shape. The dose rate was calculated in an arbitrary point assuming a uniform distribution of the radionuclide inside the source and neglecting the attenuation build-up factor and self-absorption. %K particle fluency %K absorbed dose %K energy flux density %K point of interest %U http://gw-chimie.math.unibuc.ro/anunivch/2010-1/AUBCh1916977.pdf
