On Monday, 16 October, as part of the National Research Programme for Environmental and Occupational Health (PNR EST), ANSES is issuing two calls for research projects, on environmental and occupational health and the theme of radiofrequencies. The aim is to gain a better understanding of issues that are still relatively unexplored, but which are considered to be of major importance to human health and ecosystems. Multidisciplinary projects incorporating socio-economic aspects and holistic approaches are eagerly awaited.
