Now, I hesitate to submit this at this time, given that things are not completely under wraps at Fukushima-Daiichi yet. On the other hand I won't be on Reddit at all for about 20 hours after I post this, so I figure why not.
Anyways, I have some nuclear operation training (which means the basics on biological response to radiation). The biological response theory U.S. nukes are trained under is the well-accepted "Linear No-Threshold" (LNT) model, which assumes that any exposure to radiation, no matter how small, adds some risk of getting cancer or mutation later in life. Since it is a linear model, it is assumed that receiving e.g. 10 µSv in 1 month and nothing for a year is equally as bad as 10 µSv over that year.
Not all nuclear organizations use this model, some (including in France and a United States radiation health physicists society) believe that research shows that there is evidence for a threshold dose, below which no additional risk is shown from radiation. Some believe... keep reading on reddit ➡
