As different blogs have written and different Youtube videos with Geiger Counters have demonstrated without doubt, earlier Ipads and Iphones were radioactively contaminated. Evidently depending on the nature of contamination (e.g. Cesium, Plutonium etc.) this may be a small or big health risk in the long run. http://forums.macrumors.com/showthread.php?t=1253880 With the Iphone 5 these risks seem to have increased a lot as displays seem to be produced in japan by a joint venture of the largest japanese display producers. Raw materials (e.g. plastic particles) are often stored outside. During the meltdown of the fukushima reactors radioactive particles have been dispersed over the whole contry and have desposed also on material stored outside. Radioactive material is nearly indestructible and may pose the same health risks in 10'000 years as today. From a time perspective I would guess that the complex supply chain brings in this materials in final goods around now (production 1-1.5 years after the event). Has anyone measured the radioactive contamination of the Iphone 5 (not talking about radiation of the Iphone for making calls (SAR)!)?
