Evaluation of External Dose Received by Radiation Workers in Tehran Nuclear Research Center

External occupational reports of NRC workers are provided to health physics group by the National Protection Department. These results as preliminary data are registered to a computer program that was designed using FoxBASE and Excel software by the authors. The output data provided by this program include monthly and annual intakes dose as well as external dose of workers in each department. The results show that during 1367 to 1382, the highest value of external intake dose is on an average 1.26mSv for the Radioisotope Department and the lowest value is on an average 0.48mSv for the Nuclear Biotechnology Department. Also, we have found that the workers intake the highest dose in 1371, 1372 and 1381; and the lowest value is in 1367.
