We discuss the next to the leading order (NLO) electroweak radiative corrections to the e−e+ → f−f+(γ) cross section asymmetry, for polarized and unpolarized beam scenario. The left-right and forward-backward amplitudes, with and without radiative corrections, are evaluated and compared for various kinematics. The hard bremsstrahlung is included for arbitrary energy cuts. The radiative corrections are shown to be significant and having a non-trivial dependency on the kinematic conditions. The calculations are relevant for the ultra-precise low-energy experiment Belle II planned at SuperKEKB.

A homeowner survey (n=152), designed to assess knowledge of radon health effects, concern regarding radon exposure in the home, and interest in radon testing, was conducted in a small university town in uranium-rich Nova Scotia, Canada. Although approximately 10% of lung cancer deaths in Canada are attributable to residential radon exposure, most respondents indicated that they had little knowledge of and little concern about radon and its health effects. There was a significant positive relationship between knowledge and concern but even when knowledge is high, levels of concern remain relatively low. Unless government policies address residential radon testing and mitigation, families will remain at risk of radon exposure in their homes. [ABSTRACT FROM AUTHOR]
