The difficulty being, your references are estimates based on what dose threshold?
Well, you have to go three citations deep to reach the original model they're working off of. Which turns out to be a conservative application of Linear No Threshold. Which... isn't actually testable for any reasonable value of statistical significance over the populations they're attempting to apply it to.
The BEIR VII risk models are a combination of excess relative risk (ERR) and excess absolute risk (EAR) models, both of which are written as a linear function of dose, depending on sex, age at exposure and attained age. The BEIR VII risk models were derived from analyses of data on the Japanese atomic bomb survivors for all cancer sites except breast and thyroid; for the latter, they were based on published combined analyses of data on the atomic bomb survivors and medically exposed cohorts.40, 41 To estimate risks from exposure at low doses and dose rates, a dose and dose-rate effectiveness factor (DDREF) of 1.5 was used for all outcomes except leukemia.
The biological effects of acute radiation exposure >1 Gy are reasonably well-known, are the basis for the linear-no-threshold model, and completely inapplicable to this sitation, as even the most-exposed workers at the Fukushima accident site did even approach this dose, despite the multiple situations where workers were exposed to doses in excess of legal limits.
The biological effects of short term dose less than 0.05 Gy or low-dose long-term exposure are also reasonably well-known, in that there is no statistically significant effect.
Unless you're dealing with the aftermath of a global thermonuclear war, the linear-no-threshold model is nearly useless from an epidemiological perspective, and so are conclusions reached using it.
