Effective doses were estimated in different floors of the five selected hospitals by using the (CR-39) solid state nuclear track detectors with the guide of 1CRP Publication 66. The hanged dosimeters were left for about 60 days and after etching the radon concentration, annual effective dose and effective dose equivalents were calculated. Annual effective doses were estimated as 〈 1 mSv, so the results reveal the present concentrations to be below the standard values in the studied hospitals. Therefore, no healthy risks concerning the radon activities are existing in the hospital staff and patients in these hospitals.展开更多
