Nice chart, Devlish.

Some quick googling and sloppy comparisons suggest the following: this paper and the references cited suggest that the internal radiation dose as a result of alpha radiation caused by unstable elements in the quartz is in the range of 10mGy - 70mGy per kilo-annum (1000 years). An abdominal x-ray is about 1.4mGy. Inferring from that, wearing a 1 kg (2lb) chunk of quartz around your neck for at least 20 years would be roughly equivalent to one x-ray (not accounting for the differences in effects on different tissues, etc. etc.). Assuming you have a 30g medallion (roughly 1oz) hanging around your neck, it would require some 660 years before you got to the x-ray dose.

Again, this is extremely sloppy science, but it may help putting things into perspective.

I've seen those rubber rings used as tube dampeners on miniature tubes to dampen microphonics :thumbup:
