الملخص

Cosmic radiation is one of the natural sources of radiation to which  human beings have always been exposed. The flux of cosmic rays at  the surface of the earth depends on altitude and longitude. In this 

work, the fluxes of the major components of cosmic rays in the city  of Zliten are calculated by the PARMA model by using the Excel- based program "EXPACS" version 4.09. The effective radiation dose  due to these components is also calculated using the same program.  The geographical latitude and longitude of the city of Zliten are used  as inputs to the program. The flux is found to depend on the type and  energy of the incident particle. The calculated total annual effective  does is found to be 0.28mSv/year. The obtained results can be used  to  correct  for  the  cosmic  ray  background  in  the  measurements  of  natural or artificial radiation dose.
