Abstract::
      Objective To estimate exposure dose of personnel around patients by Monte Carlo method and integration method. Methods Exposures were estimated by a Monte Carlo practical program with Visual Basic 6.0 and integration method using "pen-and-paper". Results Exposures for rectangle and ellipse sources were calculated.The difference between different methods for various sources were 0.88% and 0.61%,respectively. Conclusion The results estimated by Monte Carlo method are close to those of integration method.It is illustrated that doses of other people estimated by Monte Carlo method are significant.
