Gottagetoffthegrid was commenting on the article: "Radioactive iodine exposure in thyroid up to 87 millisieverts" from Thyroid screenings detect relatively high exposure" http://www3.nhk.or.jp/daily/english/20120309_18.html
Gottagetoffthegrid notes: "This value is essentially useless without the
activity (measured in becquerels)in the organ.
Absorbed dose in Sv is dependent on a number of assumptions including
distance from the source. it is proportional to the inverse square of the
distance, actually. meaning if you half the distance to the source you
quadruple the dose.
The standard method of calculating absorbed dose is to assume the organ is
50cm to 100cm from the source. so the actual absorbed dose coud be 100 to 1000
times higher since the thyroid is only 3 to 4cm diameter."
A Green Road Replies:
"Agree, what is the internal dose per kilogram, usually measured in Bq? By
avoiding the usual and standard way of stating radiation exposure, they avoid
any responsibility, consequences as well as allowing people to take measures to
protect their children and families.
Again, this is another spin or disinformation on top of media propoganda,
that there is no harm with internal low dose radiation.
This is right out of the playbook that apologists use,

Majia responded:
"Very instructive comment
So, the 40 millisieverts projected by the US DTRA (the Defense Threat
Reduction Agency) as the annualized dose to the thyroid of a 1 year old
California kid... (http://majiasblog.blogspot.com/2012/03/i-am-sicki-am-enraged.html)
COULD be much HIGHER for many reasons beyond this projected dose of
40 millisieverts only includes Iodine-131 (No Cesium, strontium,
plutonium, etc)...
Anyone else on the west coast getting rather worried?"
I recall an article by a female professor from Ottawa, Ontario, Canada which was rather authoritatively describing why there is no such thing as a 'safe' dose : linear response being a fiction unsupported by science. Checking http://opitslinkfest.blogspot.com/2009/08/uranium-mining-and-depleted.html I note too much information for convenient linking in comments. Let me know if you encounter difficulty reading the file. I am thinking http://www.helencaldicott.com/ is the person I had in mind.
