    "abstract": "This report presents theoretical estimates of the Power Density levels which\nmay be reached inside trains. Two possible sources of high levels of radiation\nare discussed. The first one arises since the walls of the wagons are metallic\nand therefore bounce back almost all radiation impinging on them. The second is\ndue to the simultaneous emission of a seemingly large number of nearby\ntelephones. The theoretical study presented here shows that Power Densities\nstay at values below reference levels always.",
