[edit] Alleged misuse of the unit
I deleted the following recent addition:
"Some users of very large amounts of nuclear radiation - for example, the food irradiation industry - have shifted from rads to grays, since the larger scale of the unit results in a smaller number. For example, 100,000 rads, an enormous amount of radiation (more than 1,000 times the lethal dose for human beings), can be described as 1 kilogray, or 1kGy, which to the lay audience seems like a smaller amount than a measurement that uses the number 100,000."
Ascribing political motives to a shift to internationally accepted standards seems a bit of a stretch. The food industry could just as well have used the megarad, in which cast the usage cited would be only 1/10 of an Mrad. In any case, this seems inappropriate in an article about the unit. --agr 00:53, 16 September 2005 (UTC)
[edit] More Details on risk to Humans
The Goiânia accident article data suggests that exposure to even 4+ Grays is often fatal for humans.
