If you read the chart under “Signs and Symptoms” at the URL you provided, you would have see under “2-6Gy” in the box marked “Illness” the following:
“Leukopenia, purpura, hemorrhage, infections, epilation.”
Epilation means “hair loss.”
The text of the page says “...very large skin doses can cause permanent hair loss...”
Hair loss due to transient, acute radiation exposure is brought about by the same mechanism that causes leukopenia/infections and hemorrhage: damage to the cells from ionizing radiation at a rate faster than the body can repair.
The chart on WP’s page bears out what I said earlier: By the time diarrhea sets in, hair loss is beginning.
Now, as to the nosebleeds: I’ve had more nosebleeds in a week than some people will have in their entire lives. They vary greatly between people, and without any prior history, a doctor can’t make a determination as to the cause. As a kid, I had nosebleeds that in two cases, went on for more than one day.
As a kid, I thought I was a freak. After reaching middle age and talking to friends who were now middle-aged, I come to find out that chronic nosebleeds are far more common in kids than I ever thought. The “solutions” that the medical community proposed in our age group were so inept that most of us who had these just started to keep them hidden, because we weren’t all that keen on getting a soldering iron up our noses or a dose of acid squirted up there.
So a kid comes into a clinic in an area with heavy flooding with a parent complaining of nosebleeds and diarrhea. Could it be acute radiation exposure? Yes, possibly. It is statistically more likely that the kid has ingested some untreated water and might have had nosebleed problems before, or might have been exposed to mold spores or other contaminations.
“her 6-year-old daughter had nosebleed everyday for 3 weeks in April. For 1 week, the daughter bled copiously from both nostrils. The mother said their doctor told her it was just a seasonal allergy from pollen. Her other child, 2-year-old son, had nosebleed from end of April to May.”
I just think that kids living close to the largest nuke disaster in history should be tested if they have nosebleeds three weeks running. You must know by now that they are finding high contamination outside the exclusion zone - why not test the kids? If they are fine it will assure the parents who have no reason to trust their government or nuke officials insistence that all is well. Why not accept international calls to widen the exclusion zone? What’s wrong with a free clinic seeing 50 families and those families reporting the illnesses in the thread title? I don’t know that tables in Wiki would answer all concerns because these are young children which are known to be more sensitive to radiation. Screen them and if possible, rule out rad illness. If necessary, treat and move them from their location.
Might have been a good public relations move if the gov or TEPCO had organized these free clinics - it would show their confidence that nothing is wrong and it might even show a willingness to stop lying/hiding and start telling the truth and then they’d have parent’s support.
