  "main_findings": "Electromagnetic fields from typical cellular phone transmitter stations were calculated and compared with available exposure guidelines (including thermal and non-thermal considerations). Three-dimensional exclusion zones were estimated as regions where the calculated field exceeds a chosen guideline limit; outside these zones, calculated fields are below the limit. The paper recommends a precautionary approach due to uncertainty about minimum levels below which no adverse effects can occur.",
