Within the Random-Phase Approximation the method of self-consistent determination of the isoscalar and isovector effective separable interactions restoring a broken symmetry of the deformed mean-field is given. The method allows to treat more rigorously without free parameters the properties of the scissors mode and is used to develop the rotational invariant microscopic model of the states with K π = 1 + . The spurious state separates out and has zero energy. An important consequence of this separation is the fragmentation of the scissors mode and the collectivization of the low-lying 1 + states. In addition to the isoscalar restoring interactions the consideration of the isovector restoring forces in calculations causes the splitting of the states with large B(M1) strength at low energy. The model contains a single parameter of isovector spin-spin interactions and it allows one to describe satisfactorily the fragmentation of the scissors mode and the dependence of the summed B(M1) strength on δ 2 and A in deformed nuclei.

The paper presents the results of radon concentration measurements in thermal waters of Kuzuluk and Taraklı (Sakarya, Turkey) and their contribution to annual effective dose exposure. The radon measurements were performed using RAD 7, a solid state α detector, with RAD H2O accessory. The results show that the radon activities are within the range of 0.19-5.89 Bql −1 with an average value of 0.98 Bql −1 . The associated annual effective doses have been estimated to range from 0.14 to 0.40 µSvy −1 for ingestion and from 1.81 to 5.14 µSvy −1 for inhalation of radon released from the water. These values are significantly lower than the WHO recommended limit of 100 µSvy −1
