KARAELMAS YERLEŞKESİ MERKEZ KÜTÜPHANESİ RADON ÖLÇÜMLERİ.

Radon is the major part of the natural indoor radioactivity. It is important to determine the indoor radon concentration for calculating the exposed radiation doses due to radon inhalation. In this study, the radon concentrations were measured in 2008 summer term at Zonguldak Karaelmas University Central Library by using CR-39 passive nuclear track detectors which were located on 12 different points in the library. It was found that, the average radon concentration on the Central Library was 67.1 Bq/m3. It was recorded that a radon concentration value at the new study room on the ground-floor was higher than 400 Bq/m3, TAEK's lower limit value for indoors. This may be a health risk for the library users and especially for the staff. Therefore, necessary precautions that must be taken have been stated. [ABSTRACT FROM AUTHOR]
