Research on the effects of low-levels of ionizing radiation
is fundamentally political for obvious reasons.
Hence, the timing, source, and conclusion of the study
reported here raise questions:
New data on low-dose radiation 21
December 2011Results from America's Berkeley
National Laboratory have cast doubt on the assumption that risk from radiation
is always proportional to exposure – a theory that underpins most measures for
radiological protection.
Majia here: Watching the effects of a single-dose or even multiple doses
of low-level ionizing radiation on cell repair in the laboratory is simply not
generalizable to real world exposure. The study suffers from poor “ecological
validity” http://en.wikipedia.org/wiki/Ecological_validity
Scientists will of course recognize the limitation of the study's finding for external generalizability. The purpose of the study is to CAST DOUBT on the epidemiological research on the effects of low-level ionizing radiation
The best way to study the effects of low-level ionizing
radiation is epidemiologically.
Epidemiological research looks at entire
populations and seeks to correlate disease patterns with independent variables.
Quite a lot of epidemiological research has demonstrated the impact of
low-levels of ionizing radiation.
Enenews has an entire forum dedicated to this issue: http://enenews.com/forum-effects-of-low-level-radiation
Here is a sample study conducted on the effects of Fukushima in the US http://www.radiation.org/reading/pubs/HS42_1F.pdf
I found the link to the article cited above at Ex-SKF. I am
re-posting two very concise replies to the article’s conclusion demonstrating
the problem of ecological validity:

"Contaminated
environments are no such things as one-time events.
Overwhelm an already slow process with more events than it can handle and the battle is lost."
The repair process runs inside a cell. Damage to a specific cell IS a one-time event.
If there is continuous damage to the SAME CELL, we are no longer talking about low-level radiation :)

It is called "low level" radiation because the average appears low.
"Hot particles" cause localized high-radiation spots in the body.
You could call these "cancer seeds" in some ways.
