ABSTRACT
Recent findings related to childhood leukaemia incidence near nuclear installations have raised questions which can be answered neither by current knowledge on radiation risk nor by other established risk factors. In 2012, a workshop was organised on this topic with two objectives: (a) review of results and discussion of methodological limitations of studies near nuclear installations; (b) identification of directions for future research into the causes and pathogenesis of childhood leukaemia. The workshop gathered 42 participants from different disciplines, extending widely outside of the radiation protection field. Regarding the proximity of nuclear installations, the need for continuous surveillance of childhood leukaemia incidence was highlighted, including a better characterisation of the local population. The creation of collaborative working groups was recommended for consistency in methodologies and the possibility of combining data for future analyses. Regarding the causes of childhood leukaemia, major fields of research were discussed (environmental risk factors, genetics, infections, immunity, stem cells, experimental research). The need for multidisciplinary collaboration in developing research activities was underlined, including the prevalence of potential predisposition markers and investigating further the infectious aetiology hypothesis. Animal studies and genetic/epigenetic approaches appear of great interest. Routes for future research were pointed out.

The considerable increase in using mobile communication which will increase when new technologies, such as UMTS, are introduced has resulted in further public interest concerning the possible health risks from electromagnetic fields of cellular phone networks. In view of evaluating the scientific state-of-the art, it has been shown that based on the available scientific results, the individual risk in view of proved health consequences is considered low. There are, however, indications of biological effects of high-frequency electromagnetic fields, even at intensities below the currently applied limit values or recommendations for limit values. Although the health relevance of these effects is still unclear, they give reason to precautionary measures with the object to minimise possible health risks which might affect a large number of persons. The precautionary measures recommended by the Federal Office for Radiation Protection include three principles: 1. Exposure of the general public to electromagnetic fields should be as low as possible. This applies for both the fixed parts of cellular phone networks and for mobile phones. 2. The population should be informed of risks in an objective and comprehensive way and be involved in the decisions on the construction and operation of cellular phone networks. 3. Scientific uncertainties should be reduced by means of well-directed research programmes. These precautionary measures and the significance of limit values are explained below.
