Paper Abstract

The paper summarizes the results of radon concentration and gamma dose rate monitoring in the carriages and in some stations of the Prague Metro network. The measurements reveal that both radon levels and external photon doses in the Metro are relatively low in comparison to those normally encountered in dwellings in the Prague region. On average, the radon concentrations in air inside the carriages have been found to be about 11 - 12 Bq m-3 while the levels in most stations reach values between 10 and 15 Bq m-3. Also the gamma dose rates in the stations show lower values which, in general, were in the range of 60 - 110 nGy h-1 depending on the depth of the stations and the materials used in their interiors. As to the trains, the average dose rate of passengers as well as train drivers was observed to be below 50 nGy h-1.
