Relevance of the dubious nature of LNT, the Linear No- Threshold hypothesis[edit]
See linear no-threshold model.
Inasmuch as living organic cells all have a threshold damage point below which their repair mechanisms can withstand and correct chemical injuries, etc. it is a remarkable special exception to suppose that the damage done by 100 mSv of radiation received over a period of 20 years is the same as that of a single dose of 100 mSv in a day.
But this is what the LNT hypothesis, so widely used to set radiation limits, implies.
In actual fact, there are numerous instances which contradict it. Data of health effects from exposure to radon at popular spas are an example.
There is even plausible evidence of hormesis, see the Wikipedia reference.
If the LNT model is invalid, or madder still, if hormesis applies, the low radiation rate of long lived isotopes may be harmless or even beneficial. DaveyHume (talk) 14:23, 24 October 2018 (UTC)
