A relativistic nuclear energy density functional is developed, guided by two important features that establish connections with chiral dynamics and the symmetry breaking pattern of low-energy QCD: a) strong scalar and vector fields related to inmedium changes of QCD vacuum condensates; b) the longand intermediate-range interactions generated by one-and two-pion exchange, derived from in-medium ...

Individuals living in houses with a high radon concentration have a significantly increased frequency of chromosomal aberrations in peripheral lymphocytes, the a-dose being delivered mainly by the radon daughter nuclides "'Po and 214PO. Some epidemiological and geographical studies have suggested an association between a-particle exposure via radon and the occurrence of leukaemia, brain tumours...
