Abstract:
Human beings exposed to many environmental irritative factors through their lives. One of these factors that affect the human body is the radioactive materials and ionizing radiation radon and its radioactive short life decay products, which are considered as a major natural radiation source especially in interior spaces such as homes and underground buildings like mines and subway tunnels. This issue has been focused internationally by the health organizations through out the world. Increasing radon concentration in respiratory gases and also in reparatory tract will cause the related tissues to be exposed to the alpha radiation produced by radon decay and it`s products and finally will increase the risk of lung cancer. Hence evaluation and measurement of radon concentration in interior spaces and subway station is of the most importance. The present study was conducted to measure the radon concentration in subway of Tehran. 16 stations were selected randomly from 22 stations and radon concentrations were measured with Alpha GUARD instrument. The radon concentrations have been measured in some European cities. For example radon concentration of 12.36 Bq m-3 was reported in the subways stations of Prague. Result showed that the radon concentration is 14.19 Bq m-3 in subway stations of Tehran which is almost equal to the amount measured in subway of Prague. As the threshold radon concentration is 148 Bq m-3, thequantity measured in Tehran is below the admissible dosage.
