title: Determination of angular distributions of workplace photon fields in a context of effective dose estimation.
abstract: Estimating the effective dose E with dosemeters calibrated in terms of the personal dose equivalent H(p)(10), one should take into account that the ratio of these two values, i.e. the conversion coefficient C(k), depends essentially on angular and energy parameters of the incident radiation field and is not always close to unity. Introducing the parameter that expresses the degree of anisotropy of the photon field, the paper proposes workplace categorisation and presents methods of workplace monitoring used for more accurate estimation of E at two operating nuclear power plants (NPPs) and Object Shelter in Ukraine.
