Using high-sensitivity radon ( 222 Rn) portable detectors (passive electronic devices of the type RADIM3), the airborne 222 Rn concentration in the interior of various Cypriot buildings and dwellings was measured. For each preselected building and dwelling, a calibrated detector was put into a closed room, and the 222 Rn concentration was registered in sampling intervals of 2 to 4 hours for a total counting time of typically 48 hours. 222 Rn activity concentrations were found to be in the range of 6.2 to 102.8 Bq m −3 , with an overall arithmetic mean value of (19.3 ± 14.7) Bq m −3 . This value is by a factor of two 2effective dose equivalent to the Cypriot population was calculated to be between 0.16 and 2.6 mSv with an overall arithmetic mean value of (0.49 ± 0.37) mSv.

The present study is the first to propose a theoretical framework for an exploration of the relationship among organizational culture, leader personality, and the success of hereditary transitions in family businesses. Using Dyer's cultural framework and Jungian personality concepts, the authors test empirically this framework among family businesses in Cyprus. In turn, they identify certain common dimensions of leader personality and firm culture in relation to the success of a transition, which could serve as the basis for further research on the subject.Dr. Stavrou is assistant professor at the University of Cyprus.
