CALCULATION OF THE DOSE RATE IN AN EXTERNAL POINT OF A CYLINDRICAL GAMMA RADIOACTIVE SOURCEKeywords: particle fluency , absorbed dose , energy flux density , point of interest Abstract: 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.
