This PubMed-listed study measured ambient radiofrequency electromagnetic field (RF-EMF) levels during surgical operations in 15 hospital operating rooms in Albacete, Spain, focusing on contributions from telecommunication antennas and Wi‑Fi. Using an exposimeter logging every 5 seconds across 67 procedures (~120 hours), the authors report that observed ambient RF‑EMF levels were comparable to other European indoor microenvironment studies. They report exposures in all operating rooms remained below 0.4% of the ICNIRP (2020) reference level, with the highest recorded mean value on the 2.4 GHz Wi‑Fi band.
Use of Electrical Household Appliances and Risk of All Types of Tumours: A Case-Control Study
This multi-hospital case-control study (n=316) examined associations between use of common household electrical appliances emitting ELF EMF and tumour risk. Most devices showed below-unity odds ratios, while computer screen and microwave oven use showed slightly increased odds with wide confidence intervals. Proximity to electricity transformer stations was associated with higher tumour odds, whereas proximity to powerlines was not.
